On analytical models of gas flow and chemical lasers
Abstract
Three analytical models for predicting the performance of gas flow and chemical lasers, the rectangular Gauss line shape factor (RGLSF), the Lorentz-Gauss line shape factor (LGLSF), and the model of Gao (1980), are evaluated by testing them on CW diffusion chemical lasers. For the general case where the transition is simultaneously Doppler broadened and collisionally broadened, and particularly where Doppler broadening is dominant, there is a significant difference between the predictions of the three models. The model of Gao is more reasonable than the other two models; the LGLSF model overestimates the intensity and the power output, while the RGLSF model yields results that are in between those of the LGLSF model and Gao's model. If lasing is absent the model of Gao and the LGLSF model give identical results
