HeNe Laser als Stickstofflaser (Nitrogen Laser)

[vmelkon]

you filled it with nitrogen?

@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.

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

[Zypo86]

@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.
