- hboy007's article on Nitrogen lasers
- youtube video 1

- youtube video 2

For my implementation of this idea, I've used 2 aluminum ending blocks, a pyrex 3mm tube, 10cm long, my 50KV high voltage supply, and a fridge pump for vacuum (which might not be enough). Without the resonant circuit, here are the first test results:

More soon.

    me, i have build a nitrogne laser LE with double cavity, but is it not finish , but the test it’s very good in a conventionnal discharge ( continuous discharge i mean ) but now i want to do pulsed laser with this parts; have you some time to contact me for discute to this “thing” ( excuse my english , because i’m french and … …i’m french lol )
