报道了全固态连续波571.6 nm黄光激光器.黄激光是分别由两片Nd∶YAG的1 444 nm和946 nm谱线非线性和频产生，两条谱线在各自晶体对应能级跃迁分别为4F3/2-4I15/2和4F3/2-4I9/2.实验中采用复合腔结构，利用RTP晶体II类临界相位进行内腔和频，当注入到两片Nd∶YAG晶体的抽运功率分别为25 W和14.8 W时，获得562 mW的连续波571.6 nm黄激光输出,4 h功率稳定度优于±2.9％.

An all solid-state continuous-wave yellow laser at 571.6 nm is reported.The yellow laser is from two Nd∶YAG line of 1 444 nm and 946 nm being a non-linear sum frequency,which correspond to energy levels in their respective crystal transition for 4F3/2-4I15/2 and 4F3/2-4I9/2,respectively.The yellow laser at 571.6 nm is obtained by using a doubly folded-cavity,type-II critical phase matching RTP crystal intra-cavity sum frequency mixing by 1 444 nm and 946 nm.When injected into two Nd∶YAG crystal for the pump power 25 W and 14.8 W,respectively,yellow laser at 571.6 nm of 562 mW is obtained.The power stability in 4 h is better than ±2.9%.
