提出一种全新的单抽运源、共轴双晶体实现黄光激光的方法,并对其进行了理论分析和实验研究.利用该方法在抽运功率为1.5W时,获得了54mW的黄光激光输出,激光不稳定度为5%,光-光转换率为3.6%,而利用对1064nm损耗的方法在相同条件下只获得15mW的黄光输出.该方法结构简单、灵活多样,可以应用到很多弱增益谱线与强增益谱线和频的结构当中,实现诸如491,488,593.5,555和500.8nm的激光输出.
A new single pumping source and coaxial dual-crystal method for realizing yellow laser was proposed and theoretically analyzed and experimentally studied.With this method, 54mW yellow light was obtained when pumping power was 1.5W Laser output, laser instability of 5%, light - light conversion rate of 3.6%, and the use of the method of loss of 1064nm under the same conditions only get 15mW yellow output. The method is simple, flexible and versatile, and can be applied to Many weak gain lines and strong gain line and frequency structure, such as 491,488,593.5,555 and 500.8nm laser output.
