Hey everyone. im looking to buy my first CO2 laser, with some decent power, minimum 40 watt. any ideas of where is a good place to start? thanks for any help

is this tube any good?

It good no doubt but you can find them cheaper if you wait and watch the auctions. Dont forget with that tube you will need a water cooling pump, reservoir, radiator and a psu still

IIRC a RF excited 20W just went for ~50 (tube only)

be carefull to the high voltage of the power supply, and remember to buy also the safety goggles OD>7... the safety first of all

The standard clear googles should be fine as long as he dosent point it at metal

Actually, your eyes can take a lot more of 10.600nm than the 315-1400nm range because this wavelength is not focused in the eye. OD 5 would probably be good enough. It is far more important if the goggles can stand 40W and not melt down instantly.

A high power high voltage power supply is needed, be carefull with that. Especially because high voltage and water don't mix that well. Buying a complete head would save you a lot of work, but that's also more expensive.

Polycarbonate safety glasses are a good OD10 at this wavelength anyway. You'd have to try to get anything less than 7.
