Abstract

Stationary criterion of the Ne-H₂-Cu-HBr laser mixture breakdown has been calculated using solutions of Boltzmann kinetic equation for electron energy distribution function (EEDF). It was found that increase of HBr molar fraction in the mixture leads to increase of breakdown voltage and, as a consequence, to more favorable ratio of rate constants of electron excitation of ²P (upper laser) and ²D (lower laser) atomic copper levels. Increase of Cu molar fraction in the mixture also can lead to increase of breakdown voltage due to an influence of electron collisions with copper atoms on the process of EEDF formation.
