@vmelkon no, its running at <0.03 atm (about 30mBar above the absolute vacuum).
There is no arc inside the tube, its more a "glow"-discharge.
The mirrors are still in place, there is even enough reflectivity @ 337nm and the amplification of Nitrogen itself is very high.

@Zypo86 This is at 1 atm? But how is the arc going that far? And you removed the mirrors?

@vmelkon: Thx 4 watching.
No, its just air (contains 78% Nitrogen).
But im sure its lasing from nitrogen, because i measured a single radiation line @ 337nm.

you filled it with nitrogen?
