Abstract

To minimize the effect of thermally-induced distortion and avoid the reabsorption phenomenon caused by the atomic alkali inside an alkali vapor cell (generally several or several ten millimeters long) in a diode-pumped alkali laser (DPAL) system, a novel concept of thin-disk DPALs in which alkali is sealed in a symmetric thin-disk cell has recently been proposed by referring a solid-state thin-disk laser. In this paper, we construct a theoretical model to study a V-pumped thin-disk DPAL system where the pump beam propagates along a V-shaped path. The influence of the thickness and the radius of a thin-disk cell, the incident angle of a pump beam, and the cell temperature on the output features of a thin-disk DPAL is studied by employing this model. In addition, we also investigate the effects of the profile of a pump beam such as a flat-top beam or a Gaussian beam on the uniformity of the temperature distribution and output power of a thin-disk DPAL. It has been demonstrated that a V-pumped DPAL might be better than an end-pumped DPAL. With respect to the uniformity of temperature distribution at the end-windows of a cell, the results reveal that a flat-top beam holds out a considerable merit compared with a Gaussian beam.
