Nice find! But we don't have any specs on it and too bad they don't ship outside the US ( im from Europe ), i also saw a 25W one for $375 plus shipping ( $150 for me :-X ) at plans-kits.com, 330€ is pretty cheap! Even the 40W one is a good deal for me, $700/450€, i wont find anything near these prices here :eek:
I'm actually goin to buy one of them and use it on a CNC table, focused can easily cut acrylic with gas assist. Anyone knows more buying sources ( 20W + ) ?

Actually buily both a co2 and a yag laser gun, It's do-able with about 200 worth of parts for the yag and about 300 for the CO2 If anyone wants a RTU YAG or co2 gun i'll do so for $400 and $600 respectively. Have all the parts to do the yag, for the co2 i'll need a few weeks to get all the parts together.

:cool:

It's funny that the most powerful laser generally available is one of the easiest to build for the hobbiest. Since almost all CO2 tubes are sealed these days (up to 1KW or so) it's just a matter of building or purchasing a power supply for the tube, provide some water cooling and viola, a metal blasting, eye melting good time. Not bad for a gas laser. Unfortunately, if you want to do 100W you can figure the tube to be a good four feet long. The only easier gas laser to build is a nitrogen laser if you like MW pulses. These operate in the UV range and produce exceedingly short pulses (hence the MW power output).

Solid state lasers are a blast to build (literally). Unfortunately, they require many hours of mirror alignment. Any misalignment and the cavity does not resonate. You are left with a YAG crystal that fluoresces nice but does not lase. Fortunately, you can buy resonators ready to go for very little money such as the SSY1 from the range finder of the M1 tank. The U.S. Army replaced the YAGs with Er:Glass if I remember correctly as these are more eye safe. With SSY1 in hand it's just a matter of building a circuit to energize and trigger the flashlamp. I built one using electronic parts around the shop. It was not pretty but it worked. The capacitors I used were huge. I blew out the passive q-switch on the second shot. No worries though, it's easily removed.

Here's a video of it:

They are fun and pretty inexpensive.

All the 100W tubes I've seen are 6 feet - Tough to aim.
