【Abstract】 A physical model is established to describe the kinetics and lasing mechanism of optically pumped cesium vapor laser. According to the experimental parameters, we analyze the influence of parameters of the pump light, the buffer gas pressure and the output coupler reflectivity on the output power and the optical-optical efficiency with the help of numerical method using this model. The simulation results are found to be in good agreement with that of experiments. It shows that this model reveals the kinetics and lasing mechanism of optically pumped cesium vapor laser correctly and is a theoretical guidance for the optimization of optically pumped alkali vapor laser.更多还原
