Paper Abstract

A thermodynamic approach to the problem of maximum efficiency for a chemical laser is developed. Assuming the laser radiation entropy to be negligibly small in comparison with the entropy of the chemically reacting compounds, thermodynamic limitations for the laser efficiency are obtained. A number of kinds of chemical reactions, each one being a source of laser pumping, are explored. It is shown that the most significant restrictions appear for reactions of a recombination type reducing the number of particles in the laser mixture. Photorecombination lasers are investigated in detail. The maximum efficiency for those lasers is computed over a wide range of parameters of the initial mixture.
