How it's made laser cutter

[532 with Envy]

Just found this surfing around. Thought it was pretty interesting, all be it short. The beam shaping part is pretty neat.

Enjoy if you haven't seen it yet.:beer:

Very interesting!
Nitrogen, carbon dioxide and helium? Interesting.. A really big CO2 laser with the other cases as a buffer or to help excite the CO2?

Huge bore and mirrors, I'm guessing its a multi kilowatt device.

The other gasses in a CO2 laser are both to low it's operating voltage, and in the case of sealed lasers, act as a catalyst to recombine the used gas back to CO2.

Ahh, interesting,i didn't know that Dan.
I was going to get a mill for making PCB's at one stage, but I have heard of using a CO2 laser to burn resist (i think they used paint) off a board, that's a good excuse for buying a CO2 laser. Of course one this size could just cut the copper!

Any estimates on the output power? 1KW?

Cheers! :beer:

The wikipedia article explains the purpose of each gas

3.2kW RF-excited CO2 laser resonator cavity, by Trumpf. Watched this episode last night saw it on the DVR

Kewl. Id love to own a laser cutter for random stuff. Noting in mind. Just a bunch of random metal shapes. haha.
