摘要：
The rate equations model of diode pumped metastable rare gas laser(DPRGL) is established, and taking an argon DPRGL as an example, the influence of pump intensity, metastable atom density and gain medium length on characteristics of DPRGL are simulated and discussed. The results indicate that the DPRGL has a laser efficiency higher than 55% in theory under high pump intensity (~kW/cm2). Influence of metastable atom density and length of gain medium on the DPRGL is equivalent. Main important laser parameters need to be optimized harmoniously to obtain optimal optical conversion efficiency of the DPRGL. ©, 2015, Editorial Office of High Power Laser and Particle Beams.
