My new homemade CO2 laser

Here is another CO2 laser I made. With the exception of the neon sign transformer, the glass tubing, and the resonator optics; most of the parts can be obtained from a hardware store. It is smaller than my first homebuilt CO2 laser. A section of PVC pipe is used for the cooling jacket. The PVC pipe is 28,1/2" long. PVC compression fittings have been placed over the ends of the PVC pipe. A pair of PVC caps have been placed on the ends of the fittings (opposite the pipe), and holes have been drilled through the caps. A section of 34,1/2" glass tubing passes through these holes, and down the center of the PVC pipe. The glass tube has an inside diameter of 5/16". The most significant change is found in the electrode structure. Instead of electrodes that are positioned beyond the ends of the plasma tube, this laser uses electrodes that are actually inserted into the ends of the glass plasma tube. These electrodes are just short sections of brass tubing, but these brass tubes match the inside diameter of the glass plasma tube. They are inserted about 2,1/2" past the ends of the glass plasma tube. This enables the tube coolant to be extended beyond the arc length of the plasma tube. The result is better cooling which should enable more consistent performance.

p.s. max output?

i checked out the website about the co2 laser structure but i cant find some things

if i use the air i exhale then how much helium should i use(%)? what should be the length of the laser pipe?? can i use zvs flyback transformer instead of neon sign transformer?and what about the reflective mirrors can i buy them from where ? can i make them ? the light in the laser tube is harmful? how i will know what nm protection goggles to wear?
