摘　　要：报道了全固态连续波501nm青光激光器,青激光是分别由Nd∶YAG和Nd∶YVO4晶体的946nm和1064nm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4F3/2-4I11/2。实验中采用复合折叠腔结构,利用KTP II类临界相位进行腔内和频,当注入到Nd∶YAG和Nd∶YVO4晶体的泵浦功率分别为20W和7.4W时,获得660mW的TEM00连续波501nm青激光输出。24h功率稳定度优于±4%。A all solid-state continuous-wave cyan laser at 501nm is reported,946nm wavelength is obtained from ^4F3/2-^4I9/2 transition in Nd：YAG and 1064nm wavelength is obtained from ^4F3/2-^4^11/2 transition in Nd：YVO4. Cyan laser at 501nm is obtained by using a doubly folded-cavity,type-Ⅱ critical phase matching KTP crystal intracavity sum frequency mixing by 946nm and 1064nm,with incident pumped power of 18W in Nd：YAG and 7.4W in NdYVO4, TEM0o mode cyan laser at 501nm of 660mW is obtained at last. The power stability in 24h is better than ±4%.
