Nitrogen Laser

Nitrogen laser is a Gas Laser operating in Ultraviolet range, using molecular Nitrogen as its Gain Medium , Pumped by electrical discharge.

GAIN MEDIUM

40 ns upper limit of laser lifetime (t = 36/(1+0.0128---p/mbar)ns see {Link without Title} , {Link without Title} ). Thus the laser can only emit pulses shorter than 40ns.

metastable lower level lifetime t=10 s (or 20min or 24 h depending on state (A ^3 Sigma _u ^+) and literature) see {Link without Title} . Thus it can only be operated pulsed with a max repition every 10 s, or you have to blow the nitrogen through the laser.

TYPICAL DEVICES

The medium is pumped by a transversal electrical discharge.
Since the pressure can be above 1013mbar, this is called Transverse '''E'''lectrical Discharge In Gas At '''A'''tmospheric Pressure .
