Well, not quite....yet.
I found an old Universal Laser Systems model 25A for sale at a surplus auction. It looked to be in good shape and went cheap. After I got it home and cleaned up, I found that I couldn't get the laser head to fire. I called in some expert assistance from Columbia Gadget Works, but no luck was to be had. I've since learned that RF laser tubes have a life expectancy of about 10 years before they need to be re-gassed. Re-gassing this one is prohibitively expensive and would *only* get it back to 25W. Instead, I'm looking at replacing the RF laser with a chinese glass tube. This should take it to 40W.
Either way, this looks to be a fun project. Here's a picture.
