摘　　要：A theoretical model is established to describe the thermal dynamics and laser kinetics in a static pulsed exciplex pumped Cs–Ar laser(XPAL).The temporal behaviors of both the laser output power and temperature rise in XPALs with a longtime pulse and multi-pulse operation modes are calculated and analyzed.In the case of long-time pulse pumping,the results show that the initial laser power increases with a rise in the initial operating temperature,but the laser power decreases quickly due to heat accumulation.In the case of multi-pulse operation,simulation results show that the optimal laser output power can be obtained by appropriately increasing the initial temperature and reducing the thermal relaxation time.A theoretical model is established to describe the thermal dynamics and laser kinetics in a static pulsed exciplex pumped Cs–Ar laser(XPAL).
