"First off, I cant stress this enough on how dangerous this weapon is. And yes, that is a weapon. Why? The threshold to cause permanent blindness in a person is 1 milliwatt. This laser is 40 watts total power. That is 40,000 milliwatts. Your blink reflex will not save you at that power level. You could be a long way from that weapon and still be permanently blinded. That's more dangerous in a lot of circumstances than a sword or a gun.

Secondly, "glasses" will not help you with this type of laser. What professionals use are filters that are set to a specific wavelength to block the light of the specific laser they are working with. If you don't use these properly with a weapon of that power, you could suffer serious eyesight issues even if you don't point it directly at someone's eye.

And for the love of god, if you are going to buy one of these use the proper eye protection, use them indoors, and do not point them at aircraft or you will have some serious trouble at your doorstep.

If he can do it for fun...how long before someone else does it to burn and blind?

So where is the harness to tie to the head of the frikkin shark?

Those poor balloons didn’t stand a chance (sniff)...

I may not sleep tonight. This is some scary stuff.

[NoCmpromiz]

You didn’t tell me you were working on this...

Prototype out there with the other assault weapons?

The EPA wont let you have the 100W ones any more.

If it’s a laser shotgun, shouldn’t it be able to pop more that 1 balloon in a single shot?

The boy genius does not seem worried about reflections off those shiney metal parts of the garage door. I am really surprised he has not hurt himself yet. BTW, I began “playing” with gas lasers back in 1975 at the university lab.

Ha! You’ll have something when you invent a Phased Plasma Rifle in the 40 watt range.

[xp38]

Captain Kirk had one back in his day.

I can pop balloons and start a bonefire with my 2W blue laser, what is so special popping balloons with 40W?

How about cutting wood? I know an Iranian jewler who bought a wood CNC like machine from China doing just that.
