Abstract : 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 HCl(v) is produced by chain reaction, with only the H + Cl2 reaction providing v = or > 1. Because of the large amount of HCl(0) 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)
