Abstract

Theoretical and numerical analysis of energetic characteristics of gasdynamic lasers on active media containing diatomic metastable molecules H₂, D₂, N₂ and halogen molecules was carried out. It was estimated that the most promising from the point of view of receiving the highest specific radiation energy and conversion efficiency of vibrational energy are mixtures D₂-DCl, D₂-HBr, N₂-DCl, N₂-DJ, N₂-DBr, D₂-HJ and H₂-HCl. At thermal excitation they allow to achieve efficiency from 1% to 4% and at electrodischarge excitation from 10% to 25%, the specific radiation energy reaching 60 - 300 Joule/g.
