摘　　要：报道了全固态连续波555 nm黄-绿光激光器,黄-绿激光分别由Nd∶YAG和Nd∶YVO4晶体的946 nm和1342 nm谱线非线性和频产生,两条谱线各自晶体对应的能级跃迁分别为4F3/2-4I9/2和4F3/2-4I13/2。实验中采用复合折叠腔结构,利用LBOI类临界位相匹配进行腔内和频,当注入到Nd∶YAG和Nd∶YVO4晶体的泵浦功率分别为12 W和8 W时,获得542 mW的TEM00连续波555 nm黄-绿激光输出,4 h功率稳定度优于±3.7%。实验结果表明,采用Nd∶YAG和Nd∶YVO4两种激光晶体进行腔内和频是获得黄-绿激光的高效方法,并可以应用到其它两种激光晶体进行腔内非线性和频,获得更多不同波长的激光输出。A 555 nm all solid-stat6 continuous-wave yellow-green laser with 946 nm wavelength from ^4F3/2-^4I9/2 transition in Nd ： YAG and 1 342 nm wavelength from ^4F3/2-^4I13/2 transition in Nd ： YVO4 is reported. 555 nm yellpw-green laser is obtained using a doubly folded-cavity and type-I critical phase matching LBO crystal intracavity sum frequency mixing by 946 nm and 1 342 nm. When the incident pumped powers of Nd ： YAG and Nd ： YVO4 crystals are 12 W and 8 W,respectively,the output power of 555 nm yellow-green laser in TEM00 mode is 542 mW,also its power stability in 4 h is better than ±3.7%. The experimental results show that the intracavity sum-frequency mixing is an effective method for 555 nm laser and it can be applied to other two laser crystals to obtain more all-solid-state lasers with different wavelengths.
