Investigation of amplification of light by CO2 molecules under conditions of supersonic mixing of H–H2–Xe and CO2–Cl2–He streams

The results of measurements of the unsaturated gain K₀ under conditions of supersonic mixing of reagent streams show a satisfactory agreement with the corresponding results of calculations made using a quasione-dimensional mixing model and assuming that the Cl + H₂ → HCl + H reaction is speeded up by vibrational excitation of the hydrogen molecules. The recorded values of Ko indicate that an H–H₂–Cl₂–CO₂ laser with supersonic mixing of the reagents may be developed but the energy parameters are considerably inferior to those of similar DF–CO₂ and OD–CO₂ lasers.
