Paper Abstract

A theoretical study on a He-Zn laser operating on the Zn II 758.8 nm line in the negative glow plasma of a pulsed hollow cathode discharge at intermediate pressures is presented. A detailed kinetic model of the plasmochemical reactions and radiative processes determining the inversion population on the Zn II 5p 2P3/2 - 5s 2S1/2 transition (758.8 nm line) is developed. A system of 13 non-stationary differential equations for the plasma and laser parameters is solved. The time dependent behavior of the plasma and laser parameters (excited states populations, electron and ion densities and laser gain) are numerically calculated. The behavior of the plasma and laser parameters as a function of the discharge conditions is obtained. The results are in a good agreement with experimental data.
