Abstract

A diode pumped alkali laser (DPAL) provides a significant potential for construction of high-powered lasers in the future. To realize the scaling of a DPAL, heat management and flow field inside a vapor cell should be investigated. In this paper, a new kind of gas-flowing DPAL with a disc-type vapor cell was proposed. The gain medium of cesium and the buffer gas of ethane were filled in the vapor cell with the total pressure is about 1 atmosphere. The influence of the rotate speed of a cross-flow fan on the internal gas velocity, temperature, and output features of the laser was systematically studied. The corresponding experiment was carried out, and the output laser at 894.3 nm with power of 321 W was obtained.
