A kinetic model for diode pumped Rubidium vapor laser

A physical model is established to describe the kinetic processes and laser mechanism of diode pumped rubidium vapor laser. Influences of some parameters such as the output coupler reflectivity, the cell length, the temperature and the buffer gases on the output power and the optical–optical efficiency are calculated and analyzed. The simulation results agree well with the experiments. A set of optimization parameters is obtained for designing an efficient diode pumped Rb vapor laser.
