Paper Abstract

In this paper, we introduce a new model to analyze the absorption efficiency of the laser medium for a diode side-pumped alkali laser (DSPAL). In the model, a ray trace method is employed to analyze the pump laser propagating route inside a diffusing chamber. In addition, the method, which is used to determine the total absorbed power of an alkali vapor cell, is named as the infinite convergence approach (ICA) while the random reflection is assumed to take place at the inner surface of a ceramic reflector. By considering the increase of a slit size will give rise to both increase of the input power and decrease of the reflection of the ceramic wall, we deduce that there must be an optimum slit width corresponding to the maximum absorption efficiency.
