Abstract

In recent years, a diode-pumped alkali laser (DPAL) has become one of the most hopeful candidates to achieve the high power performance. A series of models have been established to analyze the DPAL’s kinetic process and most of them were based on the algorithms in which only the ideal 3-level system was considered. In this paper, we developed a systematic model by taking into account the influence of excitation of neutral alkali atoms to higher levels on the physical features of a static DPAL. The procedures of heat transfer and laser kinetics were combined together in our theoretical model. By using such a theme, the continuous temperature distribution has been evaluated in the transverse section of a cesium vapor cell. The calculated results indicate that the excitation plays an important role during the lasing process, which might deepen the understanding of the kinetic mechanism of a DPAL.
