报道了全固态连续波555 nm激光器.555 nm激光是分别由Nd:YAG和Nd:YVO4晶体的946 nm和1342 nm谱线非线性和频产生,两条谱线在各自晶体对应能级跃迁分别为4F3/2-4Ⅰ9/2和4F3/2-4Ⅰ13/2.实验中采用复合折叠腔结构,利用LBOI类临界相位进行腔内和频,当注入Nd:YAG和Nd:YVO4晶体的泵浦功率分别为20 W和10 W时,获得1.06 W的TEM00连续波555 nm激光输出.4小时功率稳定度优于±3.3%.实验结果表明采用两种激光晶体进行腔内和频是获得激光的高效方法,并可以应用到其它两种激光晶体进行腔内非线性和频,获得更多不同波长激光输出.

A all solid-state continuous-wave laser at 555 nm is reported first time. 946 nm wavelength is obtained from 4F3/2-4Ⅰ9/2 transition in Nd: YAG and 1342 nm wavelength is obtained from 4F3/2-4Ⅰ13/2 transition in Nd: YVO4. The laser at 555 nm is obtained by using a doubly folded-cavity, type-Ⅰ critical phase matching LBO crystal intracavity sum frequency mixing by 946 nm and 1342 nm, with incident pumped power of 20 W in Nd: YAG and 10 W in NdYVO4, TEM00 mode laser at 555 nm of 1.06 W is obtained at last. The power stability in 4h is better than ±3.3%. 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 wavelength.
