Comprehensive kinetics model for DF-CO2transfer chemical lasers

A computer model of the DF-CO2CW transfer chemical laser (TCL) which treats the first nine vibrational states of DF and the first thirty-nine vibrational states of CO2is described in detail. Information theory, as it now exists, was used to correlate the large number of possible energy transfer processes involving the CO2molecule with the rather small body of published experimental data. The parameters required in the description of rate processes involving the DF molecule were obtained from the latest reviews of the subject. The model, with a scheduled mixing assumption, was used with good success to describe the operational characteristics of a variety of subsonic devices covering a pressure range of 20-200 torr. The computer model, as developed herein, is fairly complete and should be capable of describing a variety of laser options including operation at wavelengths other than at 10.6 μm, e.g., at 9.4, 12-14, and 16 μm, with only minor alterations required.
