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 electro-optic switch)

How would I go about building this? Think I can make it run on AAs (probably need to build a step-up transformer if so)?

Thanks!
 





Man ---
You need to do some reading about CO2 lasers. CO2 gas is the lesser part of the plasma charge. Mostly He and N2 plus a little other stuff. The mirrors can be acquired from damaged tubes.. You might find them on ebay. ZnSe is expensive and the beam is invisible. The power supply will be large because of the coils and high voltage.
Keep us informed.........

Yeah, I thought it would be stupid.
 
I didn't say stupid -- I implied that it is a serious undertaking even for me and I have built a CO2 from the glass up. It took years to do but that was 40 years ago! Technology has changed and occasionally, there are really small CO2 lasers advertised on ebay.

Still, I don't have the funds for such a big undertaking.
 
I'm at a loss as to what in the heck anyone would use a multi watt non visible "pointer" for.

So I can paint targets for heat-seeking missiles :-) And for self-defense.
 
Ohhhh. I like war! When you are making billions dealing these to the militaries of the world... Send me one!
 
Take a high power nitrogen laser design. Replace the windows with ZNSE, fill with Co2 laser mix at atmospheric pressure. Add a external high reflector.
Stir well. Adjust mix pressure for max power.

congrats, you just built a pulsed TEA CO2. (google it)
