Abstract
The results of a survey of pressure-broadening data in the literature pertaining to species present in H2 − F2 chemical lasers are described. Pressure-broadened linewidths of the HF vibration–rotation transitions were found to depend strongly on the vibrational and rotational quantum numbers, as well as on the perturbing species. The experimental data were incorporated into a rate equation model of the pulsed H2 − F2 laser; where experimental data were unavailable, theoretical values were used. The calculations made from this model demonstrate the importance of including such detailed pressure-broadening information. Recent experimental results of Kwok and Cohen for HF V → R,T deactivation were also included in the model and were taken to be a multiquantum process. Comparisons of model predictions for pulse energy and pulse duration with several atmospheric-pressure laser measurements showed good agreement.
