Abstract

A two-dimensional program is applied to simulate the chemical dynamic process,gas dynamic process and lasing process of a combustion-driven CW HF overtone chemical lasers.Some important parameters in the cavity are obtained.The calculated results include averaged pressure and temperature,zero power gain coefficient, laser spectrum, output power, chemical efficiency and overtone efficiency.Based on the numerical simulation,the influence of entering gas flow parameter,nozzle structure and nozzle array length on the performance of HF overtone lasers are investigated separately.Because of small zero power gain coefficient of each HF overtone spectral line,the saturation degree of gain medium in the cavity is the most important parameter to influence the overtone efficiency of HF lasers.
