Chinese Scientists Have Developed the World's First Destructive Laser Rifle (popsci.com)
PopularScience: Chinese scientists have developed the world's first destructive, man-portable laser weapon. However, there is more to the story of this cool looking, but "less than lethal" directed energy device. The laser rifle is the ZKZM-500, developed by Xian Institute of Optics and Precision Mechanics in Xian, Shaanxi. It's manufactured by the Institute's subsidiary, ZKZM Laser. Weighing at 6 pounds (about the weight of a typical assault rifle), the ZKZM-500 has a range of 2,600 feet. The ZKZM-500 uses a lithium battery with enough power for 1000 two second shots (keep in mind, those 1000 shots may not be at full power). According to Institute designers, its laser is powerful enough to instantly scar human skin and tissue. It can also ignite clothing, knock a small drone out of the sky, or even ignite a fuel tank. That would place its power output around 100-500 watts (most surgical lasers top out at 100 watts).
Wow you can predict precisely where the laser will hit and have the mirror at the ready? Or you're simply walking down the battlefield with a full dress mirror??
Mostly random stuff.

Yes, please walk down the battlefield wearing a full dress mirror. It's completely safe and will not get you instantly spotted and killed by conventional weapons at all.
No, but that's also not necessary. All it takes to thwart any laser based weaponry is to come covered in something that reflects and scatters light well. The effect of a laser weapon is based upon absorption of the light. Technically if you know what kind of laser it is, the color of your clothing might already be enough.
Laser guns look cool and futuristic in sci fi movies, but they really make pretty poor weapons in reality.
We used to have a Bill of Rights. Now, with the rights gone, all we have left is the bill.
No need. Fire off smoke rounds or aerial spray and keep the area soaked with haze or mist. Laser = useless.
Wow, it's almost like you picked up on my sarcasm.

Seriously?!
Defeated by a simple mirror.
Trying to deflect random laser small-arms fire with some sort of wearable or man-portable mirror system is...sub-optimal.

Is it attachable to sharks yet? If not, why?
Like a spray can of water..... a garden sprinkler could thwart this. it would setup a suspended cloud of prismatic reflectors (water droplets) , the laser would have to burn through the cloud, transferring sufficient energy to each droplet to vaporize it. If those droplets are constantly in motion due to the use of a high pressure fine mister and are hence being replaced continiously, that could be an effective shield.

While I congratulate the Chinese, I can almost guarantee that some country (which you all know very well), is going to scream: -
"That's our IP", "Why do the Chinese steal our IP?"
But the Chinese will borrow a leaf from their Russian friends and will retort, "the dogs bark, but the caravan goes on."
Congratulations to those Chinese, from one Slashdotter here.
these are 10-15W Max portable lasers, this thing is probably 100-500W.
You can buy solid state lasers with 15-20 W output on Chinese sites that run on 12v, most laser engravers have that kind of power.

But you can't dodge a bullet, or tunafish. Maybe you get lucky. Once. Only the lucky ones.
How can people take seriously such improbable bovine manure ? Very clumsy propaganda. What's next , The Gaher 313 on slashdot ? It is not even funny.
Oh, you were being sarcastic were you? How interesting.
Ignite clothing, cause scars, burn and char flesh, instantly permanently blind eyes, and so on, and so forth.
This weapon is much worse than simple killing; I'd say it's a complete flouting of the rules of war. Nice job making it, scientists, but much like the atom bomb, now we have a lasting problem on our hands.
Likely you are a troll, but a laser will happily burn through a mirror. Depending on the wavelength and the makeup of the "mirror" not all that much power is needed.
Under the âoeProtocol IV on Blinding Laser Weapons, of the 1980 Convention on Certain Conventional Weaponsâ these are illegal to use against humans.
So... nice to have and make drawings in the sand with... I guess
Yeah, that's a helpful reply.

"enough to instantly scar human skin and tissue" very effective against "model armies" - if you know what I mean ;)

On the other hand, you could also shoot and hit things without line of sight.
It's made from Chinesium, meaning it'll break after two shots.
If those droplets are constantly in motion due to the use of a high pressure fine mister and are hence being replaced continiously, that could be an effective shield.
Unlikely. Whatever speed the mister can push the droplets out in is insignificant compared to that of light speed.
The laser will vaporize the droplets instantly and there is no way you can get the mist to move in fast enough to matter.
You would do better with ashes or a small sandstorm or anything else that is harder to burn through.
From the description in looks like it would be pretty useless against traditional body armor so the trick is to just treat it as if someone shoots at you with a musket. Avoid being hit in the face, modern armor will protect you just fine, and shoot back before they manage to hit anything important.
Sounds like the more useful application would be to mount it on some automatic aiming device and use it to take down drones, but the range is a bit low for that.
I think it needs a couple of iterations before it can find a niche where it is better than a regular bullet.
I guess it is a bit like EMP weapons in that regard. They never really took off since traditional bombs takes out electronics just fine.
If the US were to steal the designs and market them to the rest of the world?
Yet another Chinese BULL SHIT
What are you congratulating them for? You do realize this didn't actually happen did you? People are so gullible. Maybe Trump is right about "Fake News".
Fortunately laser rifles are exceptionally effective against straw men.
All it takes to thwart any laser based weaponry is to come covered in something that reflects and scatters light well.
Try moving around on a sunny day in reflective gear to see how well that works on a battlefield.
There is no independent confirmation of the existence of this rifle. Absolutely none.

How would you know? Have you ever seen anyone been killed wearing a full dress mirror? Didn't Think so pal
That laser doesn't seem useless to me.
If you are one of those normal people who engage in the act of sleeping at home at night,
there's a high chance of your property and therefore livelihood, if not life, getting torched by any of the easily flammable textile being zapped from a distance. Lasers such as these are an arsonist's dream.
Just imagine how fabulous the soldiers will be, covered in sequins.
One of the ways of modern open war is not to kill enemy soldiers but to injure them in a way which demands even more resources from the opponent. A laser gun able to blind opponents is very useful. Give it a really good optical targeting assist to support massive range and a high rate of fire and you have a really good open field weapon.
in ~1955 the US military experimented with backpack fed man-portable lasers. they could blind and burn at several miles. damage equipment and ignite ammunition. but were deemed far too power hungry, heavy, inefficient, etc for use.
So the mirrored Disco Ball is making a comeback!
soon everyone will have them.

"That's the way to do it" - Punch
The real challenge for military planners is not handheld laser weapons but ground and plane based laser weapons. It isnâ(TM)t necessary for a laser weapon to destroy a plane or a ship. It only needs to take out the external elements of targeting and defensive systems leaving it vulnerable to conventional attack. An Aegis combat system will protect an aircraft carrier against a cruise missile. Chinese and American military planners understands that without a working Aegis system an aircraft carrier is nothing but a large and slow moving target. Laser weapons are a game changer in that situation
Perhaps we are all missing the true end use for these lasers.
Maybe their intended use is to blind night vision devices and infrared cameras.
I read that the Chinese were using lasers to prevent pilots from getting near their bases and the island that they built in the South China Sea.
Perhaps this is an extension of that use.
Surely if the laser is vaporising water droplets it the steam and heater air will cause a large amount of diffraction.
It is prohibited to employ laser weapons specifically designed, as their sole combat function or as one of their combat functions, to cause permanent blindness to unenhanced vision, that is to the naked eye or to the eye with corrective eyesight devices. The High Contracting Parties shall not transfer such weapons to any State or non-State entity.
Not a500W laser on that distance
You can see lasers with the right optics...just follow the source and take them out. Second, a 2 second burst is very impractical...do you know how hard it is to keep a dot on anything moving that is 2600 feet away...even breathing will cause the dot to move several feet. Ever wonder why snipers are laying down, with a tri-pod, have controlled breathing, and other tactics to keep the dot on point for a split second.
That's also the opposite of stealth, so your gear would have the choice of being hard to track for guided weapons or hard to destroy with a laser, but not both. We rarely arm our soldiers or equipment with only one weapon system...

FTA: "The ZKZM-500 has plenty of Chinese predecessors in directed energy weapons. Chinese police and soldiers have long been equipped with 'dazzler' laser rifles. These include PY132A, WGJ-2002 and BBQ-905, which are designed to target the optical imagers and sensors on enemy vehicles, aircraft and drones (since China's signed the United Nations Protocol on Blinding Laser Weapons, which bans the use of laser weapons that cause permanent damage to human eyes)."
The OP was likely being sarcastic but let's address this common misconception: a mirror is not a magical shield against laser weaponry. Go investigate some of the issues with powerful ground-based lasers developed for anti-ballistic warfare use. Laser aiming/focusing mirrors routinely blew up because no mirror is a perfect reflector of all energy. It may only absorb a small percentage of what's aimed at it but when you're putting out that much power it doesn't matter; that small percentage is enough. Same goes for us watery meatbags.

- The laser module - sure it exists but it is going to be big and need water cooling if it's going to be of any use
- The weight - the module itself for a 500W laser comes in ~5kg. Even if they somehow got the module to fit in the 6kg they claim it weighs, the batteries and watercooling will pack on an additional 6-10kg.
- The power requirements ~0.3 kWh (not accounting for losses from water cooling and other gear), that requires a small motorcycle battery, even if made from Lithium, not something you easily carry around in a 6kg package.

That will work for the 1st day. What about the 2nd day, when you have run out of smoke rounds?
Or are you assuming infinite logistical depth?
So by employing a certain color of laser, I'm forcing you to dress in clothing that reflects and scatters that color? I guess I'll use a bright red laser then, since that color of clothing will stand out nicely in most landscapes we'll be fighting in.

This fake story again?
actually you could wear a reflective camouflage, that is, normal camo pattern in a reflective vest ... it would be the middle term between the two, it would reflect most of the laser, but still be hidden enough ... unless the light conditions are exactly behind the shooter... from other angles, it would not make that difference from normal camouflage

And when was the last time a sophisticated modern military force ran out of "smoke rounds", Bill? Does that seem like an urgent problem for a country that spends a trillion on defense? huh? Did you read the article? Your dubiously-existent chinese flashlight runs for just over 30 mins.
Or are you assuming infinite logistical depth?
I thought laser weapons were among the forbidden weapon categories. Is China not a signatory to the Geneva Protocols?
Probably risky - if the burning outer layer deposits soot on the mirror, then the laser will heat it rather than being reflected. Doesn't take much heating to disrupt a reflective layer.
--- Most topics have many sides worth arguing, allow me to take one opposite you.
A video of people on a rooftop allegedly setting stuff on fire with a laser proves precisely nothing. Even if a laser is being used, there's zero indication that it is the handheld device that's emitting it.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
Although China has signed the UN convention on not producing weapons "intended to blind", I'm guessing that means "as their primary function", since all bigger lasers (included ones fielded by the USA) can burn through solids, so can sure toast your retina in a heartbeat.
These smaller "rifles" would be useless against a well-equipped conventional military force; while you're trying to burn them somewhere (at a 100 yards) they've already shot your balls off at 150...

All it takes to thwart any laser based weaponry is to come covered in something that reflects and scatters light well. The effect of a laser weapon is based upon absorption of the light. Technically if you know what kind of laser it is, the color of your clothing might already be enough.
Only if there's no dust in your clothing, and it is exactly, precisely the same color as the laser, and it is only that color. And if the color is a coating, not molded in, because then the laser will strip away everything but the pigment.
It's a cute sci-fi trope, but the idea that wearing clothing of the correct color is a meaningful defense against a laser weapon is totally incorrect. If you just have a little contamination on a mirror, a laser will destroy it. You think you're going to get clothes to do the job? If that did make any sense, you'd want to wear fully white clothing, because that would reflect all visible frequencies. A flat white surface actually reflects more light than an ordinary mirror, because the light doesn't have to pass through the glass twice before you see it. But it still reflects less than 90% of the light, which means that as long as the remaining 10% is sufficient to discolor the garment, that 90% is going to go downhill rapidly.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
That's ridiculous. Nobody is going to shoot at a reflection of themselves walking down the battlefield, that's suicide!
Probably easier to design something ablative, or something that carbonizes when hit with the laser - essentially leaving behind a highly-heat resistant and insulating carbon layer. The black parts of the space shuttle were made by carbonizing resins (RCC panels). The result would be a ruined, brittle fabric - but it would protect one's skin from the laser.

Is the opponent not also logistically constrained? The idea that one side could fire lasers at will for an indefinite period of time while the other side does nothing in response except deploy countermeasures is a little strange.

With an energy rating of 100-500w, the direct hit isn't the only hazard. I used to be a laser safety officer at my employer and a laser of that energy level is a class IV laser, whose beam is hazardous in close proximity. Even if you're not in the direct path, the radiation emitted by a laser beam of that power is hazardous.
Fire that puppy 1000 times and you've absorbed enough radiation that is unhealthy.

It probably wouldn't work very well. Anything you do that reflects light is going to more or less completely defeat the purpose of the camo. You'd still be better off in most cases with camo, as they aren't going to hit things with the laser that they can't see.
How many people do you think you can get dressed in scales? It's not like there are a who lot of lizard people outside of DC.

There would probably also be some sort of weapon that would leave deposits on the mirrored surfaces so that the reflectors aren't as effective.
A racist is literally a person who thinks there is such a thing as races. Nothing more, nothing less. ...They were literally created by the proponents of eugenics and racism. They didn’t exist before the 18th century!)

In this week's episode of, "Queer Eye for the Laser Guy" ...
Look back up at my post, now look back down, you're on the Internet. Now look back up. I'm a signature.
Germany was once called "land of the poets and thinkers".
That description came up at a time when the UK had full "copyright" laws, while Germany had none such thing. As a result, German creativity spiked, while the UK one was nearly dead.
All because some cokeheaded publishers (not creatives! never creatives!) decided they could steal ALL the money from the actual creatives and from their fans, by sitting in-between, and leeching off all the money. That was possible, because back then, there was no Internet, and creatives needed somebody to distribute their works. So the publishers blatantly made up the concept that you could "own" mere ideas, information, data ... And that the creatives needed to give them that "ownership" in order to get the "privilege" to be distributed by them. They lobbied (which still was literal treason and punished with 20 years of prison if found out back then) the government to grant them an exclusive monopoly on this made-up "good", to stifle its naturally infinite abundance, to raise its worth from zero to as much as they could squeeze out. Giving as little as humanly possible to the creatives, while acting like the whole thing protects creatives! (At the time when Napster arrived, I worked in the music industry, and the actual artists got about 3.5%... when they were a big artist... from which said artist still had to pay studio expenses. The "producer"... who did nothing special that the artist couldn't do, but snort shitloads of cocaine all day, got a whopping 60% of that CD price! ... This has massively changed in favor of artists since file sharing got big. So much for "protecting artists".)
This is the sole and only purpose of the concept of "I.P." ... A concept that literally incompatible with the laws of physics (specifically, causality).
To steal money, and not work for it. While calling anyone who doesn't let them steal, is ironically called a "thief".
So the Chinese, like me, don't give a fuck about your leech vulture capitalist crime scheme, and say "If all you give me, is a mere COPY of the RESULT of somebody ELSE's hard work... Then all you will ever going to get, is also a mere COPY of the RESULT of somebody else's hard work!"
Notice the EXTREMELY IMPORTANT DIFFERENCE between the actual work, which is worth money, and the mere COPY which is worth just as much as it took work to make the copy. Which is usually very very close to absolute zero!
Oh, and by the way: Only 10 years ago, morons who were pro "I.P." were still laughed out of Slashdot. Nowatays, even this former bastion of tech clue, seems to have been fully brainwashed.
Kilts are for day to day use, for battle you wear a floor length sequined ball gown. The idea is is blind your opponent with opulence.
All it takes to thwart any laser based weaponry is to come covered in something that reflects and scatters light well.
Try moving around on a sunny day in reflective gear to see how well that works on a battlefield.
Try using smoke which is already used to mask tactical troop movements and line of sight.

Of course those deposits absorb the laser energy, which causes them to heat up, and a sudden spot with a high temperature difference on most materials that high reflectivity mirrors are made of will break under those conditions.
Also, a low quality mirror doesn't work so well with higher power lasers. I talked to the guys at the local university who were demonstrating a laser that has a loud pop noise when fired (the beam is enough to instantly ionize the air and cause a mini thunderclap), and they told me about trying to use a regular hand mirror with that laser. Let's just say it didn't work and they needed a new hand mirror.

Also, much like a diamond, RCC is a rather special material, it's not just a layer of carbonized material.
We do have several ablative materials that have been tested for use against lasers, but I don't have any details on those.
However, the better armors and their inserts can alread protect reasonably well (or better) against a low power laser weapon like that, as well as defend against conventional weapons.
Sorry about being so geeky on this subject. I've been poking around with it for decades
Smoke does work very well for that. Common in sci-fi is a type of smoke grenade to specifically mess with lasers, but that might not be totally fictional anymore. One of the old things I saw listed on a Darpa list of tech they were wanting to look into was something like that. It was a long time ago, so maybe somebody has already created one that works better than the usual smoke grenade when it comes to blocking lasers.
Yeah, but these are only for drones and not shooting people in the eyes... honest!
(People always find a way around limitations one way or another. Just research about the napalm/incindigel mess)
Except when the lasers, like these, are outside the visible spectrum. So what color is "invisible" ?
Phased plasma rifle in the 40-watt range.
Totally correct, but they are basing the "rifle" due to size and configuration of the weapon instead of a physical component like riflings.

Also, much like a diamond, RCC is a rather special material, it's not just a layer of carbonized material.
I didn't mean to imply that they could design fabric that could transform itself into RCC when carbonized - I was just using it as an example of how pure carbon makes a nice insulator with a practical example. RCC would be overkill anyway, as it's not important that the fabric be durable or reusable - just that it absorbs and dissipates a short burst of laser energy. In the worst case we are talking 500 watts for 2 seconds. That's 1000 Joules, which is less than the energy that a bulletproof vest needs to dissipate. It seems feasible, that's all.
Never apologize for being geeky on Slashdot! :)
W..w..W - Willy Waterloo washes Warren Wiggins who is washing Waldo Woo.
That's when you pull out the dinner-plate-sized disc of chobham armor. To think people cover entire tanks with the stuff... what a waste.
It is best to think of lasers as emitting very specific wavelengths of EM radiation, in a very straight and thin line. Those that emit wavelengths detectable by our eyes (mostly in the red, green, and blue ranges since that is what our cones are designed to perceive) are considered visible; those that don't are not. For comparison purposes, consider that sunlight contains a wide range of wavelengths from longer than visible (e.g., infrared) to shorter than visible (e.g., ultraviolet) and it is actually the latter, the ultraviolet, that tends to cause sunburn and associated cell damage.
Nonaggression works!
And, unlike conventional bullet gun, anyone should see where it comes from (or at least the direction). So it is a no go in reality.
The US have heavily tested laser weapons already and for the most part they aren't practical compared to conventional weapons in most cases. This is one of those cool Sci-Fi ideas that doesn't pan out. The problem is most lasers aren't very efficient and the ones that are (chemical lasers) use stuff so nasty they'd be deadly to the soldier carrying it if it burst or broke. Not to mention rain or dust or hazy day would reduce its effectiveness. It's probably a concept weapon that can give you a burn or blind but compare that to oh getting hit by a 50 cal round which would blow parts off you. It's likely a test concept weapon for experimenting but I highly doubt it'll ever come into widespread use.
Bill doesn't think things thru anymore.
Anything coming from the motherland or her neighbors is automatically flawless. Bill knows the US stopped producing smoke rounds. He has inside knowledge. He's a spy, but we let him think we don't know.
The fact that he's married to a local is all you need to know.
If only Maurice Ward hadn't taken his recipe for Starlite to the grave with him.

Wrong. The electoral college chose him.
So is running over people with tanks, but that's never stopped China in the past.
I'll take one in the 40 watt range
How will the enemy deend themselfves against laser rifles? Wrap themelves in tin foil or carry mirrors?
Being, you dumb fuck
Military units around the world are already equipped with a decent laser defence mechanism. It's called a smoke grenade. It even comes in bigger sizes, from mortars all the way up to the bigger cannons. The US army at least now has smoke screen rounds engineered to also block out IR so as to defeat thermal and IR sighting systems. (and therefore would also be a good defence against IR up through the visual range laser wavelengths.)

Let's assume bad ass laser rifles become the military's standard issue rifles.
So we gonna use laser tracers to make em visible (ha), or will soldiers need to wear special goggles to see the lasers?
Or will an intelligence source analyze the battlefield and relay info to the soldiers?
Will next-gen soldier armor rely on cutting edge insulation w/ crazy high r-values? Maybe we'll go back to full suits of armor. And if we're there, we might as well integrate powered exoskeletons. Maybe we'll just move onto mechs.
And if we have mechs, and we can develop secure quantum data transmission, we have take pilots out of the mechs.
Of course battery tech will have to advance by crazy leaps and bounds, too. (and hyper-capacity batteries will have a transformative effect on society)
This gonna be cool.
The supposed use will be as a less-than-lethal weapon for applications like crowd control.
Post may contain irony: discontinue use if experiencing mood swings, nausea or elevated blood pressure.
Lethal lasers will heat up and char mirror surfaces so quickly mirrors won't work.
Sounds to me that you just wanted to make a veiled racist comment about how the Chinese do nothing but steal IP. Guess they're too stupid to make up thier own inventions, amirite?
#notallchanks
So, disco ball armour and glitter-based battlefield dress then?
My, aren't your war preparations special!
Bullshit! Go to damned near any truck stop (I work for and suggest Love's) and you'll find all the lot lizards you want. You're either intentionally lying(because you are one) or not even fucking trying....GAH!
I'm so sick of that site, for over 5 years they've done Geo IP redirection, ensuring if I click their links, I'll be just redirected to the front page of their Aussie web site.
It's some antique internet rubbish. I've even emailed them, it's moronic.
Can I put a hit out on their site here? Can someone please take them out?
Perfect mirrors turn this weapon back on its user.
...or are they just pretending they did? Kind of like the guy who tried to patent an engine for faster than light travel.
"But the Chinese will borrow a leaf from their Russian friends and will retort, "the dogs bark, but the caravan goes on."
And this is exactly why -- or one reason why anyway -- trade sanctions are being imposed.
"Free" trade only works if both sides respect the other's laws. China does not.
In fact they very sneakily impose trade sanctions in almost invisible ways... like not putting a tariff on imports of Product X but then issuing a government mandate that anyone in China who needs a Product X must buy it from a Chinese supplier.
The screams that Trump is starting a "trade war" are ridiculous. China has been conducting trade war against the US for decades, and past Presidents just bent over for it.
No more.
Sequins and camo don't really mix...
All it takes to thwart any laser based weaponry is to come covered in something that reflects and scatters light well.
Try moving around on a sunny day in reflective gear to see how well that works on a battlefield.
OTOH, you could have reflective gear with an ablative camouflage coating over it. The laser would burn off the camo, then get reflected from the reflective layer.

I like how Oriental racism towards white people is so much nicer and civilized than white people's racism towards Orientals. It's refreshing. I'm serious.
HAHAHAHA +100000 funny
Weapons designed to operate through blinding are prohibited. If the weapon happens to blind as a side effect, that is fine.
If you just have a little contamination on a mirror, a laser will destroy it.
I think part of the idea here is that like soft body armor works against low power firearms like handguns but not rifles, a mirror layer inside of clothing will protect against laser weapons which are only marginally powerful enough to be lethal which will be the man portable ones for an extended time.
Pew pew pew
No.
People chose him over the rabid Clinton.
Don't make fun of Bill. Just because you are not already one of the millions of people he has said he would not hire for his amazing, yet unnamed, business, which desperately tells of how there are no suitable candidates for the many open positions at unspecified salaries in unspecified locations for non specific duties, doesn't make him a child molester.
Also, anyone know where i can find a cardio-thorasic specialist with twenty years experience using a no.7 blade obsidian scalpel to perform ventral bypasses on obese patients of Inuit descent, using Johnson and Johnson military grade gauze and 100ml vials of benedyne? Note using 250ml of 50ml vials is not an acceptable equivalent.
Compensation depends on experience, but I'm willing to go up to $15/hr for surgical time. No commute, training or other costs covered. Surgeon must own own tools. This is for an at will, zero minimum hour weekly contract, with a 30 minute response time for 24/7 on call needs. Must be local, own own vehicle and able to lift heavy objects.
This is why I always buy a complimenting set of infinite mass when I get my incompressible, massless, frictionless pulleys and rope for physics experiments. Just knot up some rope, toss the infinite mass pulley on top and let it absorb the finite energy of the laser.
Retroreflector ftw?
If I have a laser of that color, then I can have a sensor that can detect that wavelength too.

a glitter grenade.
The smoke grenade should take good care of both.
We used to have a Bill of Rights. Now, with the rights gone, all we have left is the bill.
In other words, pretty much any army that could matter in any foreseeable conflict.

Yeah, there's some spin on this, all right, but I don't think it's the photons.

I guess we found out who is using all that efficient coolant.
Mirror camo won't do much.
For one, you need a CLEAN mirror - otherwise dirt on the face of it will absorb energy, heat up, etc. and be quickly defeat the mirror...and clean (as in spotless) on the battlefield doesn't happen
Then you need a highly efficient mirror. Even if you reflect most of the energy, what's left will heat up and distort the mirror which greatly reduces it's selectivity...and then you don't have a mirror anymore.
And then...you need it to be flexible enough to WEAR which doesn't generally go with high efficiency.
So pretty much nope nope nope. Any laser powerful enough to for use for the battle field will defeat mirror 'armor' quickly.
You can get rich if you own a politician, but you have to be rich to buy one in the first place.
If they are rifles, how do they get the laser to spin? Are the barrels really rifled? I guess it sounds better than "laser gun"
you obviously have never been in a battle.
That'd be tricky though - the big advantage of lasers is that they're largely point-and-hit. Any deposit-leaving weapon is going to be back to trying to hit the target with a chunk of matter moving a million times slower - if you can do that, then why use the laser at all?
