摘要
首次报道了全固态连续波572 nm黄光激光器,黄激光是分别由两片Nd∶YAG的1444 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LBO晶体I类临界相位进行内腔和频,当注入到两片Nd∶YAG晶体的泵浦功率分别为24 W和14.8 W时,获得592 mW的TEM00连续波572 nm黄激光输出。4 h功率稳定度优于±3.6%。
All solid-state continuous-wave yellow laser at 572 nm is firstly reported. The yellow laser is from two Nd:YAG line of 1444 nm and 946 nm have a non-linear sum frequency, the two lines corresponding to energy levels in their respective crystal transition for 4 F3/2 - 4I15/2 and 4 F3/2- 4 [9/2,respectively,the yellow laser at 572 nm is obtained by using a doubly folded-cavity, type-Icritical phase matching LBO crystal intra-eavity sum frequency mixing by 1444 nm and 946 nm. When injected into two Nd:YAG crystal for the pump power 24 W and 14.8 W,respectively, TEM00 mode yellow laser at 572 nm of 592 mW is obtained at last. The power stability in 4 h is better than ± 3.6%.
