Abstract

A new-dimensional self-consistent numerical model of vibrationally nonequilibrium gas flow in glow discharge positive column has been constructed. The influence of volume recombination, pre-ionization effect, discharge region length and gas flow velocity on the CO₂ laser active medium gain has been investigated. The results of numerical calculations made a good agreement with the results of IR luminescence diagnostics of CO₂ laser active medium with transverse pumping.
