Incredible home made low cost CO2 Laser

[LokisMischief] wrote in to the tip line to let us know about this incredible home made CO2 laser. This thing is a complete DIY beauty, from the PVC cooling jacket to the toolbox based controller.  The whole thing is essentially built from DIY parts,  hand blown glass for the laser tube, plumbing store mirror mounts,  a PVC cooling jacket with a caulked glass viewing window, and a neon sign transformer with a variac to control output. Even the optics are completely DIY, a hand drilled gold mirror and a NaCL window made from a polished chunk of  icecream salt! [ThunderSqueak] says the control box only cost 60 bucks, and the rest of the parts don’t look too terribly expensive.

We could only find one video of the setup in the variac section of the site, and it was just a test the amp meter in the controller (no lasing anything at all).  [ThunderSqueak] does make a note on the to do list about doing a good laser-y demonstration video, which we are looking forward to.

If you want more DIY CO2 laser action check out this other one or some plans for one.
