Numerical analysis of a chain-reaction H2–Cl2 chemical laser

A kinetic model is developed for a chemical laser utilizing the chains reaction between Cl₂ and vibrationally excited hydrogen. Numerical calculations are made of the influence of the degree of excitation of the H₂, and of the pressure, chemical composition, and temperature of the mixture on the lasing characteristics of this laser. It is shown that in spite of slightly inferior energy parameters, compared with HF lasers the system under study has better characteristics than known HCl laser systems.
