一种LD泵浦的新型自倍频激光器─M－NYAB与NYAB自倍频激光器的对比

A new type of self-doubling lasers -M-NYAB versus NYAB

研制成功世界上第一台ＬＤ泵浦的Ｍ－ＮＹＡＢ自倍频激光器。比目前ＬＤ泵浦的ＮＹＡＢ自倍频激光器性能更好：输出波长为０．５３１μｍ的绿色激光，容易得到基横模运转，阈值泵浦功率降低三分之一以上，为８．２ｍｗ，输出功率达到２２．５ｍＷ，斜效率达３．８％。文中简单报导了实验结果。

The first M-NYAB self-doubling laser pumped by LD in the world has been developed. The properties of the lasers are much better thanthat of NYAB self-doubling laser pumped by LD. All of M-NYAB selfdoubling laser pumped by LD can operate in TEM00 mode with 8.2 mW of threshold pumping power which is two third power of the NYAB selfdoubling laser pumped by LD. The output power of 0.531 μm green laser is 22. 5 mW with 3. 8% of slope effeciecy.
