Abstract

In this paper, a mathematic model is established for the end-pumped continuous-wave cesium vapor laser. The threedimensional calculation of amplified spontaneous emission (ASE) is presented. The ASE flux is calculated from every point through all possible paths inside the medium. We systemically investigate the influences of the cell radius, cell length, and cell wall temperature on ASE. The results show that the ASE effect can be decreased by adjusting these key factors. To the best of our knowledge, there have not been any reports on the ASE estimation in an end-pumped DPAL so far.
