Hello friends!

I have an extremely rare "Passively cooled" 13W rf excited co2 laser + driver for sale. Works great! Runs on 28-32v

This laser wouldn't be for sale if I wasn't in the market for a cheap thermal camera. I figure I'd use the camera much much more than this laser. So if you have one you're looking to get rid of, I'd surely be interested.

Looking to sell it for 250$ + shipping.

Hmmm got a video of it running? I wanted a smaller co 2 for my wood projects. What are its optics like?.

@trussmonkey25, no, I dont have any videos of it running. It works perfectly though and if you are interested in purchasing it, I don't see any reason why I cant make a video.

Optics are in perfect shape. No burns, scratches or anything.

Oh, and what makes these units unique is the fact that they are passively cooled and compact. No noisy water pumps!!!!

I also must note that the voltages I have listed are wrong!! Ill change those in a min. Operating voltages are 28-32v. Those voltages are the reason I really haven't done much with it yet.

@jcranmer, sure is! Assuming you want my almost used stick :p. It's just there for reference size.

No, this runs off of 28-32v DC. You could probably pickup a 120VAC to 28-32V Meanwell PSU to run the lasers supply. They're like 40 bucks though.

Will the output of the 120vac to 32 volts be ac also. Simply a stepdown transformer?
The part shown next to the tube shown is the rf part that makes this laser sing?

A simple stepdown transformer will not work since they output AC. If you wanted to use a simple stepdown transformer you "could" but you'd have to rectify it and smooth it out with some capacitors along with making sure you remain within that 28-32v range.

This is something I would recommend since it would essentially be plug and play. This unit wants about 280W to operate nominally. So this supply would work great. Sorry I don't have one to give you :(.

The big heatsink is where the RF magic happens and the small piece with the black heatsink is the power supply for the rf board.

This would be really cool if it worked with a lower voltage, for handheld use with some big lipo packs...

Jeff recommended a lab style power supply. So that will bring it to life. I thought of using weed whacker batteries. But the other way is much more sensible

The most awesome thing I can think of doing with this laser (what I was going to do but never did) is use a pack of LiPo cells and a voltage regulator. This will make the laser portable. All you'd need to do is figure out a way to keep it all together and make it pretty. Would make for a really "dangerous" but fun laser gun.

Would consider trading this for a thermal camera if anyone has one they would be interested in letting go. That's what I'll be investing into anyway when this goes.
