      Blue is cool. Also, hard to do. Between the two, you get expensive.

      Red lasers are cheap because they're cheap to make, though the suspiciously cheap ones are, indeed, suspiciously cheaply made. Green lasers are pretty close to the human eye's peak responsiveness, so they appear brighter at a given power level than red or blue lasers.

      There are all manner of lasers. CO2, Argon, and other gas lasers. Chemical lasers. Diode lasers. And several other varieties. Hand-held (and small bench) lasers are commonly diode lasers. Low-power red laser diodes are approximately free, which is why they show up everywhere. Infrared laser diodes aren't terribly expensive, even fairly high-powered ones. There is no such thing as a green laser diode. Hand-held green lasers are DPSS lasers, in which a high power infrared laser blasts a fancy neodymium compound that outputs a different infrared frequency that in turn hits a frequency-doubling crystal which finally outputs 532nm green light.

      The take-home message here is that blue laser light is hard to get so it's expensive. It's also not terribly useful unless you actually need the high frequency for denser data packing. Green laser light is harder to get than red laser light, but in addition to looking cool it legitimately is more visible per watt. Check out the CIE luminosity function - 650nm red light appears about 8x dimmer per watt than 532nm green light. A $100 15mW green laser therefore should appear almost as bright as a $200 200mW red laser. Even though production of green laser light is less efficient than production of red laser light, the green laser should consume somewhat less power than the red one.

      - The big diff between the $1k and $2k blue laser is the frequency. 473nm vs 405nm. It is not unusual to see a 5x price difference between 100nm of emission. Same thing with LEDs.
      - Basically, there is quite a bit you can do with 405nm that you can't do or do as well with say 650nm (red). Briefly: fluoroscopy, higher speed optical comms, nano-scale work, gas spectroscopy, holographic storage, etc. As we get into the higher frequencies even more applications such as portable weapons, etc.
      - The average home has 1/2 dozen or more laser diodes. Most are in the cheaper/lower frequencies. As the cost comes done on the higher frequencies, this will open up the floodgates. If you recall, when laser were first invented they were called a, "good idea with no practical use". Sound like some of the posts to this thread?
      - The higher the frequency, the more effective the energy against the target. As a result, a 20mw 405nm is more destructive than a 60mw 650nm for example. Incidentally, the reason laser diode power output is rising in disk players is that is allows the disk to be spun faster. This maintains the average energy per data area. Historically, the biggest impediment to faster CDR/RW speeds has been the availability of the high power laser diodes. We are going to continue to see applications held up by the availability of sufficient laser diodes in desired frequencies and power levels until investment dramatically increases.
      - One of the difficulties with the higher frequencies is that the same energetic advantages of the wavelength work against the very materials of the diode. Basically the diode attacks itself. This reduces the lifespan of the device for a particular drive level. Early blue laser diodes had a lifespan measured in 100s of hours. The 405nm devices used in the disk players may only be good for 2-5k hours, depending on the drive level. This will improve of course. Eventually the 405nm 20mw devices will cost less than $5 and last 50k hours or more.
      - Basically, putting an expensive laser diode in a handheld pointer is mostly for fun at this point. People with money who also know lasers realize that with a 405nm device they are going to see very unusual things. For example, imagine what a 405nm pointer looks like when shone against a 3d object painted with fluorescent material. Some people buy the latest game or sci-fi movie, others buy rare laser pointers. As these devices become more available, creative people will find more uses for them. Like I said earlier, laser diodes are already quite common in the average home or business.
      - Our government is going to have a real problem with high power laser diodes in the near future. Without going into details, advanced laser diodes can have significant public threat. Right now the law is fairly lax and not enforced. I am not for more laws but I don't want to have to wear eye protection every time I attend a public event. It will be a sticky issue and I hope that whatever the solution, it provides the most liberty for scientific experimentation.

Converted, this means 440 Ws. So if you have a 4W Laser, you would need to point it on your target for 110s to even deliver the same ammount of energy (not considering your target moves, energy is lost due to reflection, cooling, etc.) But now your gun does not deliver that energy in 110s, but in lets say 0,1s (guessing). So you need about 1000 times more energy. (so you need to point only 0,1s). This means you need 440000 Ws. A Li-Ion battery has a energy density of 160 Wh/kg. http://en.wikipedia.org/wiki/Lithium_ion_battery So this means you'd have to lug around 1kg of Li-Ion battery only for a single shot.

Can the diameter be adjusted to do more damage? How much power is required to actually drill the target rather than totally cauterizing the wound you create? Would spinning the laser help, or would the laser fail to deliver enough power before it's moved off to a cooler spot?

      Honestly speaking, a laptop battery could deliver about 20 watts of continuous power for an hour or two. From what I understand, that's a lot of firepower for a cutting laser. It won't outright destroy the target (you're still only delivering a maximum of 20 watts!), but it may allow for precision destruction. Remember, a sniper has to lead his target with a normal weapon. A laser has the advantage of What You See Is What You Kill (WYSIWYK!). The distances involved in most sniping exercises are inconsequential to laser weapons.

      The flying "anti-satellite" laser that the DOD has is packed in a commercial-airliner-sized jet, but a good portion of that space is not taken up by energy storage. It's a chemical laser, which means that it's a system that basically is there to mix some compounds. When they mix, they lase; the output is then simply focussed and aimed. A good portion of the space is taken up with chemical storage.

      I only asked about a few watts, not a military grade, anti-tank weapon. :)

      FIRST PROBLEM: I think you'd need more than 3w to provide a serious weapon for the battlefield. I mean, HIGH SPEED PLASTIC WELDERS use lasers with over 100W output...I would expect nothing less of a weapon intended to cut through skin as fast as a bullet would. Higher power requirements mean big, bulky batteries.

      Sure, you can burn things with a measly 3w laser, but only if the enemy stands still.

      Let's just say you need the minimum power (100w) laser welder I linked to get the skin-cutting performance you want (still pretty low, considering industrial cutters get up to the 10KW range). That's a lot of battery to lug around.

      SECOND PROBLEM: it's not just the power SOURCE that's a problem, it's the power dissapation that's at issue.

      The efficiency of lasers is pretty low to begin with - numbers I've seen are in the %30-40 range, best case, and less than %1, worst case.

      So, let's take our 100w laser rifle, and give it a pretty high efficiency (%40): to generate 100w output continuous fire requires an input of 250w!! That means you have to dissapate a massive 150w while continuously firing the device.

      This leads to the THIRD PROBLEM: laser efficiency decreases significantly with the increase in laser temperature, making cooling an even more important problem. If you don't control the temperature with active cooling, your laser spirals out of control in a feedback loop. Thus, you MUST have a bulky cooling solution.

      Until they make power virtually free and tiny, man-portable laser weapons are a pipe dream. The good news is, there are DARPA-funded research programs to produce more efficienct lasers, and they've already reached levels of %65. Their eventual goal is %80 peak efficiency. Now all you have to do is solve the energy problem :D

    Hi, Good day, its very interesting to read your comments, some are very insightful. Let me explain why we used a Blu-ray laser disc player to obtain the laser diodes. The reason is that there are only 2 manufactureres (Nichia, and Sony) that manufacture Blu-ray diodes in all of the world, and they are located in Japan. When the project was first envisioned two months ago, we called Nichia to obtain pricing on a diode, the cost quoted for 100pc was 2000$ US per unit, but the problem lied in the fact if we could ever get them, as there are global shortages of blu-ray diodes. We had to find a better way to create this laser.

    Our alternate plan, which was the one we ended up going with was to buy Blu-ray disc players* from the USA, and have them shipped into China. This was a slightly cheaper and also more reliable way of guaranteeing we would have something soon. Our profit margin on this product is by far the lowest compared to all our other products, and at this point we are in the negative from the development of this product. We hope to make this money back through a few sales, but we believe that in the long run, the world will know that Wicked Lasers is willing to innovate; that all true laser enthusiasts will recongize our efforts and help us revolutionize the world of lasers.

    Lastly, some of you believe that we have targeted Slashdot as a "slashvertisement". However, we had no intention of seeing this story out on Slashdot, it came as a pleasant surprise. In fact, we were hoping that with i4u.com (the original poster of the story), we could gain some publicity in their tech-oriented crowd. We are very proud that Slashdot has acknowledged this story, and we hope that we will have something even more newsworthy to give to you guys next time! Thank you for your time to read my reply.

    Best Regards,

    *Blu-ray disc players are not released in China, the only option is to purchase a Sony AR Laptop at 3,500$ to obtain the Blu-ray drive. At the time of this project conception HD-DVD XBOX drives were not yet released. We will be considering cheaper options in the future to offer a better price to our customers.

    If you look at their product overview page here: http://www.wickedlasers.com/products_overview.php

    And scroll on down to the red Pulsar laser, take a good hard look at the image there. Does it look familiar?

    It couldn't possibly be from the box art (and background) of Counter Strike: Source could it? Oh no no no. This is a reputable company that makes quarity product in China! Why they'd have no need at all to steal images for their own marketing.
