“…The maximal output power of 32 W was observed at 100˚C. This result is in agreement with that of our previous study [14,15], which is relate to the saturated vapor pressure and reabsorption of stimulated radiation. In the near future, resonator optimization and power scaling of the laser system would be carried out and investigated.…”

A diode pumped alkali laser (DPAL) provides a significant potential for construction of high-powered lasers. To realize the scaling of a DPAL, heat management should be optimized. In this paper, a new kind of gas-flowing DPAL was proposed, in which a small cross-flow fan with diameter of 125 mm was set in the center of a cylindrical vapor cell whose diameter and thickness is 160 mm and 55 mm, respectively. 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. A mathematical model was constructed to systematically study the influence of the rotate speed on the internal temperature distribution and the output features of the laser. And then, the experimental study of the laser system was then carried out, in which the output laser at 894.3 nm with power of 32 W was obtained. The results show that both the velocity distribution and temperature distribution are greatly influenced by the rotate speed of the cross-flow fan, and then the heat generated from the DPAL can be took away efficiently, which is very important to the output performance of the laser system. These results indicate that this new type of gas-flowing DPAL might be a good choice for power scaling of DPALs.
