  • @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?
