摘要：

We report a high-efficiency cesium-vapor laser with a high-gas-pressure (similar to 3-atm helium and 0.49-atm ethane) cell pumped by a high-power external-cavity laser-diode bar. Peak laser power of 12.1 W at 894 nm was obtained, when the absorbed peak pump power was 23.1 W. The achieved slope efficiencies with the incident pump power and the absorbed pump power were 33 and 81.7%, respectively. (C) 2009 The Japan Society of Applied Physics DOI: 10.1143/APEX.2.032501
