LBO I类临界相位匹配腔内和频572 nm黄光激光器

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~4F_(3/2)-~4I_(15/2)和~4F_(3/2)-~4I_(9/2).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TEM_(00)连续波572 nm黄激光输出.4 h功率稳定度优于±3.6%.

LBO type-I critical phase-matched intracavity sum-frequency mixing 572 nm yellow laser

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 ~4F_(3/2)-~4I_(15/2) and ~4F_(3/2)-~4I_(9/2),respectively,the yellow laser at 572 nm is obtained by using a doubly folded-cavity,type-Icritical phase matching LBO crystal intra-cavity 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,TEM_(00) mode yellow laser at 572 nm of 592 mW is obtained at last.The power stability in 4 h is better than ±3.6%.
