PLASMA DYNAMIC LASERS

Reshetnyak,S.A., Shelepin,L.A.: 1975, Sov.Phys.Tech.Phys., 19, 1076.

In the rapid expansion of a dense, highly ionized plasma in the plasma laser, the electron gas is cooled, the plasma recombines, and lasing occurs on atomic transitions. A method of calculating these developed using quasistationary analytic population distribution functions over discrete levels. A quenching effect is considered for a hydrogen plasma and a radiative mechanism for emptying the lower level is analyzed. The possibility of an effective collision mechanism for lithium, helium, and beryllium plasmas is pointed out which would permit the use of large plasma volumes for generation. The dependence of population inversion on a number of parameters is studied.
