I will!

I shall wage war against high prices!

So I can paint targets for heat-seeking missiles :-) And for self-defense.

Still, I don't have the funds for such a big undertaking.

Yeah, I thought it would be stupid.

Thanks! I just wanted to know whether it was possible to build a portable CO2 laser, and now I know. I think I'l buy a 200 mW red laser now!

Is most of the size in the cooling system, or the actual resonator? Is the reason b/c the resonator needs to be a certain size, or what? I suppose I could wrap the resonator in a Peltier cooler. Would Q-switching it reduce the heat output? How many volts does the discharge need to be?

Okay, what do you recommend? How much do infrared (980 nm) blocking goggles cost? Or FIR-blocking goggles? What about my CO2 laser question; I posted it in the gas laser forum too.

Are polycarbonate photochromatic lenses sufficient? AKA my regular eyeglasses? Is it possible to build a pocket-sized Q-switch CO2 laser with a power output of a few watts/pulse?

Is it possible to build a pulsed CO2 laser pointer? I bet I'd need: 1. A glass tube with gold mirror at one end and a semi-gilded mirror at the other, filled with CO2 (of course!) 2. A zinc selenide window 3. A device to Q-switch it (either by rotating the semi-gilded mirror or some type of...

What if I focused it to a tighter point, so the intensity is increased? Anyway, I'm more interested in burning things like steel wool, matches, paper, dried paint off of stuff, dazzling attackers, things like that.

Hi! I'm looking to burn things like matchs, wood, paper, maybe cut aluminum foil, what type of laser pointer should I buy? IR, red, green, blue, violet, UV? Which would be more powerful at cutting things, a 400 mW IR laser, or a 400 mW UV laser? I know they don't make UV pointers, but...maybe...
