Wicked Lasers Introduces Handheld One-Watt Green Laser
First time accepted submitter (and Slashdot coder) cogent writes "Wicked Lasers, famous for last year's 1000mW handheld blue laser, and infamous for its handling of six-month-long backorders, is now selling a green version. There are three power levels, each priced at $1/mW (300mW, 500mW, 1000mW). Since the eye is far more sensitive to green than to blue, this is pretty much the state of the art in putting-dots-on-stuff technology. Wicked Lasers sent out an email promising to handle backorders much better this time."
Adds reader whitedsepdivine: "There is currently no disclaimer that this is not a lightsaber on their site, so we can only assume that this version is."
As cool as this is, you really don't want one. Specular reflections off other surfaces can blind you instantly. There's no way to actually hand hold it with it powered in any remotely safe manner. If it doesn't terrify you, you don't know what you're dealing with, and if it does, you probably don't want one.
I would add avoiding *scattered* light to the list of warnings. (It has a BRH Class 4 warning label, which does include that wording.) A bit safer perhaps than other wavelengths because your eye responds with very high sensitivity to 532nm green (so you're not in *quite* as much danger as you would be from short-wavelength blue or, far worse, UV), but you definitely want to be wearing 532nm notch filter glasses with side shields as even looking at the beam spot on a white (and non-specularly-reflecting) surface could give cause fairly rapid eye damage. (And you can't control who's staring at the beam spot in most cases.) Note: The beam spot of my 40mW DPSS laser is significantly brighter than I'm comfortable looking at for long..
.. not a good idea.)
(Wicked also has pretty emphatic warnings in the manual about never aiming it at satellites. Me, I wouldn't want to be the guy who gets sued by or faces criminal charges from the operators of a commercial or government LEO satellite whose sensors are damaged by one of these. Goes at least double for whoever tries to show off to the ISS crew
Take care that this counts as a weapon in many countries and possession without a matching laser-permit can land you in jail. Here you need a permit for any laser class 3 or above, i.e. > 5mW. Also it is very easy to permanently blind someone with this thing by reflection only. If you are stupid enough to point it at a flying airplane or helicopter (quite a few people are), you will go down either as a terrorist or for attempted murder. Or with this thing likely for completed murder as most helicopters and quite a few airplanes do not have a second pilot. Pointing it at a moving car can have the same effect. It is quite amoral to sell these to normal people.
Most ACs are not even worth the keystrokes to insult them. Be generically insulted by this and ignored otherwise.
I'm normally the first guy to say, "oh leave people be", but this kind of thing is one where I think I'd be happier with a person having to have some kind of minor license to buy one... if only to just create some token hurdle to ownership.
The problem with lasers is that, whereas everyone knows how dangerous a firearm can be... people tend to treat lasers like toys with no consequences. "Yeah, yeah, don't shine it in anyones eyes... got it." But I have never seen someone wear eye protection when using one, much less making sure everyone for miles around had eye protection when they're shining it through windows, at passing cars, etc. And they're coming down in price so any goofball can screw around with pretty powerful ones.
Maybe it's time to make sure people buying these things really understand how bad they can screw up with these devices in just a moment of bad decision making? And I don't mean clicking "I Agree" to a paragraph on a website that they didn't read. Maybe something more like a amateur radio test?
For me, it's awkward talking favorably about regulation. Maybe I'm overly concerned about something that isn't really an issue.
There is no legitimate use. I have a 4mW green laser pointer, and that is clearly visible in daylight and quite enough. The only use I see is as an anti-personnel and anti-aircraft weapon. In quite a few countries possession only will land you in jail. And there are quite a few stupid scumbags that point these at airplanes or helicopters for fun. One went down for several years here recently for pointing it at an ambulance helicopter in flight. That is 4 times attempted murder. (pilot, EMT, doctor, patient). Quite even making the pilot unable to fly safely for 15 minutes can kill the patient. You can do that with a much smaller laser already.

NO, it's a damn weapon. If you're out walking the streets with this, the police should be about as suspicious as if you're walking around with a kitchen knife in your pocket.
I'm almost certain that someone in my town has something similar to one of these. My apartment's fairly high up overlooking a couple of main roads and residential neighbourhoods, and one afternoon I was watching TV when I was hit by an extremely bright green light that seemed to come from somewhere down the road, and which then briefly filled my whole vision. It wasn't a particularly pleasant affair, luckily whatever dickhead was shining it around didn't keep it in one spot for long. They really ought to be classed as weapons - it only takes one careless turd to wave one of these at a set of flats / office / condo and you've got a good chance of flashing someone in the eyes.
But I have never seen someone wear eye protection when using one, much less making sure everyone for miles around had eye protection when they're shining it through windows, at passing cars, etc. And they're coming down in price so any goofball can screw around with pretty powerful ones.
FWIW when I bought the 350mW laser I'm using on my CNC mill to do marking and drill soldermask stencils, I'd already purchased a set of laser goggles designed for that wavelength, and always wear them when it's powered up. The reason I did that is because I've worked in three high-power laser labs, two commercial and one academic, and in all three at least one coworker had partial blindness from an unintended exposure. (In two of those, the person had been wearing laser glasses, and had just gotten unlucky with a specular reflection off a tool sitting on a desk that deflected the beam upwards between the edge of the glasses and the person's cheek, which is why I got against-the-skin-all-the-way-around goggles.) One dubious benefit to high power lasers in private hands is that it'll most likely be the owner's eyes that get fried in the reasonably short term.
Nostalgia's not what it used to be.
