I saw a lot of interisting construktions of lasers on http://www.powerlabs.org/laser.htm and http://members.iinet.net.au/~pterren/lasers__Nitrogen.htm#Nitrogen laser trouth I have qite lot of skils at hight voltage area I am not able to build any of those devices because I didn't find any scheme or described construction how to build that. If you have any experience with gas laser, help me please.
