DIY Homemade Co2 Laser

Finally got this finished. Its a flowing gas Co2 laser. There is a full write up here, issue 7: Homemeade solid copper mirrors, borosilicate tube with acrylic tube water jacket. Ends/electrodes/mirror mounts are brass tank fitting from the plumbing suppliers. I was totally eductated by the internet to build this, so beware I am completly unqualified to give advice... The vacuum pump, which I don’t show here, is real in this case. It is an Edwards Dual Stage. Power is Oil Burner Ignition transformer. I found it dumped at the side of the road a few years ago. That first test is uncollimated BTW, its not so clear in the video. Thanks to: Guy Ovadia Jarrod Kinsey (website and YT) Samuel M. Goldwasser from Sams Laser FAQs. kartopla1982 (YT)
