摘　　要：报道了全固态连续波554.9nm黄光激光器,黄激光是分别由Nd:YAG和Nd:YVO4晶体的1342nm和946nm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4F3/2-4I11/2和4F3/2-4I9/2。实验中采用复合折叠腔结构,利用LBO晶体I类临界相位进行内腔和频,当注入到Nd:YAG和Nd:YVO4晶体的泵浦功率分别为20W和8W时,获得850mW的TEMoo连续波554.9nm黄激光输出。4小时功率稳定度优于±2.5%。A all solid - state continuous- wave orange laser at 554.9nm is reported, 1342nm wavelength is obtained from ^4F3/2 -4^I11/2 transition in Nd： YAG and 946nm wavelength is obtained from ^4F3/2 - ^4I9/2 transition in Nd： YVO4. Orange laser at 554.9nm is obtained by using a doubly folded - cavity, type - I critical phase matching LBO crystal intracavity sum frequency mixing by 1342nm and 946nm, with incident pumped power of 20W in Nd： YAG and 8W in Nd： YVO4,TEM00 mode orange laser at 554.9nm of 850mW is obtained at last. The power stability in 4h is better than ± 2.5%.
