摘　　要：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 configuration of 589 nm yellow laser with a single LD pump source and coaxial double crystal was proposed. When the incidence pump power was 1. 5 W,54 mW yellow laser at 589 nm was obtained,the optical to optical conversion efficiency was 3. 6% ,and the laser instability was about 5% . A conventional method for 589 nm laser was also tested under the same conditions,only 15 mW yellow laser was obtain. The configuration of single pump source and coaxial double crystals is compact and flexible,which can be used in many sum frequency lasers,such as the 491,488, 593. 5,555 and 500. 8 nm laser,and so on.
