The results of a survey of pressure-broadening data in the literature pertaining to species present in H(2) - F(2) 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 H(2) - F(2) 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.
本文描述了对文献中与H(2)-F(2)化学激光器中存在的物种相关的压力展宽数据的调查结果。发现HF振动-转动跃迁的压力展宽线宽强烈依赖于振动和转动量子数,以及微扰物种。实验数据被纳入脉冲H(2)-F(2)激光器的速率方程模型;在没有实验数据的情况下,使用理论值。该模型的计算结果证明了包含此类详细压力展宽信息的重要性。Kwok和Cohen最近关于HF V?R,T失活的实验结果也被纳入模型,并被视为多量子过程。模型对脉冲能量和脉冲持续时间的预测与几次大气压激光测量结果的比较显示出良好的一致性。
