Ai. Kutsenko et al., SPECTRAL AND TEMPORAL CHARACTERISTICS OF THE RADIATION EMITTED BY A FAST-FLOW ELECTRIC-DISCHARGE CO2-LASER, Kvantovaa elektronika, 22(4), 1995, pp. 325-327
Experimental and theoretical investigations were made of the spectral
and temporal characterististics of the radiation emitted by a cw fast-
flow electric-discharge CO2 laser. A discharge chamber, separate from
the cavity, was filled with a nitrogen-helium mixture at pressures of
6.5-12 kPa. When the input energy was above 200 J/g, simultaneous stea
dy-state stimulated emission of the P(22), P (20), and P(18) lines was
observed. At input energies up to 100 J/g the laser radiation had a b
roader Spectrum.
