摘要: 报道了一台高效率二极管泵浦Nd:YAG薄片激光器,采用高效均匀泵浦耦合技术,在峰值功率1.008kW,占空比25%, 电-光效率大于45%的二极管激光阵列泵浦下,用一块1mm厚的Nd:YAG薄片激光介质,获得了峰值功率404W,平均功率101W的准连续激光输出,光-光效率达到40%,电-光效率超过18%。Abstract: A diodepumped Nd:YAG disk laser with high efficiency is reported. A fourpass optical coupling system is well design to obtain a nearly flat top pump profile. An average output power of 101 W is achieved from one single disk with a thickness of 1mm. The average pumping power of the diode laser array is 252W with an electrical to optical efficiency of more than 45%. The optical efficiency of the laser system is 40% and the electrical to optical efficiency is more than 18%.
