Paper Abstract

Diode-pumped alkali lasers (DPALs) have attracted a lot of interests in the recent years because of their high Stokes efficiency, good beam quality, compact size, and near-infrared emission wavelengths. Until now, the thermal features have been only analyzed in an open alkali cell. In this report, we established a mathematical model to examine the heating effect of a static sealed rubidium cell by means of a Finite Difference (FD) procedure. After assuming the absorption coefficient of the alkali vapor, the temperature distributions of a real sealed rubidium vapor cell have been acquired for different powers and beam waists of the pump. The analytic conclusions would be helpful in designing a feasible DPAL.
