摘要
A computationally efficient numerical simulation of a diode-pumped alkali laser (DPAL) has been developed. It considers the thermal lensing effect by a wave-optics optical resonator model coupled with a simplified gas-flow model. The calculation results indicate that the proposed gas-flow model correctly predicts the temperature distribution of the active medium heated by exothermic reactions. As a result, there is good agreement between the calculations and experiments, especially with the output power as a function of the gas-flow velocity. The calculations have shown that the population of the high-lying excited levels of the Cs atom is negligible within a pump power intensity of 10 kW/cm(2).
