That is what I expected. As long as no eyes are damaged in the process....

It is always a good precaution to wear eye protection when dealing with high power lasers. Most reputable sellers on Ebay as well as dedicated sites such as WickedLasers sell special goggles or safety glasses for use with high output lasers. I have a couple of pairs myself.
I believe the army is mounting a system called "THOR" on their Humvees that can easily cut thru steel barriers. They are using it to blow up land mines right now. The coolest thing is that they are actually firing 2 beams, the Chemical Laser, and a guiding 505nm green laser, so it looks like the green laser is the one doing the cutting! I love that! intimidate the enemy, switch off the visible part when you need to snipe.
GalaxyX tell me what you think about it and what you are using it for.
GalaxyX: I warn you! You don't like on the floor, I vill have to stun you!
Ronald Held: Go ahead. Stun me.
GalaxyX: Werry sorry but... <pulls trigger>
Ronald Held: Agggghhh! My eyes!
GalaxyX: <looks at phaser> Hehe... must be the radiation!

For sure. Well, I'm really scared with this thing actually. Apparently the scattering is so high at this power level that just looking at the dot on a wall can potentially cause eye damage. People that have done it have damaged their ability to see the colour green, some regaining it back within 6-9 months. The safe indirect viewing distance is supposed to be about 120feet for a non reflective surface. And it should be safe pointing it at the night sky provided nothing up there bounces it back to you.
Accidental direct exposure to the beam in the eye means instant eye damage at the level of a chemical laser.
Sooooo..... I actually plan to read up on EVERY safety precaution and to ALWAYS wear my goggles when pointing in areas where it can potentially reflect back. I'll probably only use it to point to the night sky and the top of trees in the distance when I'm out camping. I wouldn't use this thing in the city, radar could probably pick up this beam LOL

That wasn't Galaxy, it sounded like Chekov.
I think I should pass on that laser.

On the bright side (pun intended), you've now got a perfectly silent, totally untraceable home defense weapon. Just aim it in the general direction of the attacker's head and wave it at him until he stops blinking.
Thought I'd revive this thread. Got my laser after 3 months of waiting. HOLY CRAP IT'S BRIGHT!! You ALWAYS have to wear the goggles with this puppy, the reflection off even flat black surfaces is painful to stare at directly.
I think I'm going to need stronger goggles. So far, treating it like a gun is paying off.
Theoretically it can be used for home defense, but you better have goggles handy, otherwise you're blinding yourself too. Here in Canada you're not allowed to defend yourself, but will have a chance in court if you only use retaliatory force equal or lesser than the thief. If they came in with guns, and you have guns to point back, that's somewhat legit, even though you're still in a heap of trouble. If they just had pocketknives, even if you smack'em with a bat, you still used more force than necessary.
Screwy lewy laws IMO.

Where I work we have three 4KW lasers for cutting material.
FOUR THOUSAND WATTS.
Yes.
Cuts through steel pretty quickly.
The laser is enclosed in a guard housing, and the entire cutting chamber is enclosed... and you STILL have to wear heavy goggles AND a face-mask over the goggles... and the entire laser room is a "restricted area." You have to have a key-card to get in there while the laser is cutting.
Look up the home-shop machinist forum and ping a fellow named Evan on there. He's an expert in optics and lasers and he'll be the first to warn you that ANY LASER more powerful than a red-dot laser pointer is a danger to the operator and anyone around it.
In fact, here in the US there are very very strict laws governing the sale and use of low-power lasers because of the threat of accidentally blinding drivers and pilots with them.

^ Oddly, for the past few months I've been working on a manuscript in which a rebel faction in the U.S. makes widespread use of kilowatt-class lasers as a purely antipersonnel weapon. The big scare about it is, even if you find something thick enough to work for cover, they can still intentionally blind you by firing the laser beam at any random object within your line of sight, even if you're not looking directly at it.
I'm thinking if you want something safe to playwith, then a phaser rifle styled water gun with light running down the water jet fiber optic style might be the best bet. Use very bright LEDs or a bank of lesser powered lasers aimed only at the water supply--just enough to get the water to glow. Chemicals, blacklight, something.
The arctic blue from wicked lasers got banned?
