Abstract
The chemical kinetics characterizing a DF-CO(2) transfer chemical laser were verified by utilizing a subsonic laser system which, for most conditions, could be approximated as premixed and at constant pressure. In such a laser, fluid dynamic effects are minimized, and the role of the kinetics model in characterizing the DF-CO(2) system is emphasized. Predictions of zero power gain, DF(v) number densities, thermocouple temperatures, and laser power were compared with data for an optical cavity pressure range of 21-79 Torr. The results show that the kinetics model gives an accurate description of the DP-CO(2) optical cavity. Mixing phenomena were found to become important at cavity pressures below 40 Torr.
