A quantitative analysis is presented of an H2 Cl2 cw chemical laser, including the influence of stimulated emission on the reacting medium. Numerically determined solutions encompass one-dimensional fluid mechanics, chemical kinetics, radiative de-excitation, and their mutual interaction. The excited HClv is produced by chain reaction, with only the H Cl2 reaction providing v or 1. Because of the large amount of HCl0 produced by the Cl H2 reaction, lasing primarily occurs on the 3 to 2 and 2 to 1 vibrational bands. A chemical efficiency of 7 is predicted, with a cavity pressure of 0.1 atm, no diluent, and a substantial excess of H2. A comprehensive parametric study examines the effects that result from changed initial cavity conditions, mixture ratios, and output coupling. Author
