摘　　要：Nd:YCa4 O(BO3 ) 3 (简称 Nd:YCOB)是一种新型自倍频激光复合功能晶体。利用 Dat-achrom - 50 0 0型染料激光器作为抽运源 ,横向抽运钕离子原子比为 8%的 Nd:YCOB获得了 530 .2nm绿色自倍频激光输出。在样品未镀膜的情况下阈值抽运能量小于 2 m J,绿光输出能量最大为1.0 3m J,能量转换效率约为 3.3%。Nd:YCa4O( BO3) 3,known as Nd:YCOB,is a new nonlinear multifunctional crys- tal.By using Datachrom- 5 0 0 0 dye- laser as a pumping source,a Nd:YCOB( 8at% ) self- fre- quency- doubling laser from1 .0 6 μm to0 .5 3μm has been realized.The wavelength of the frequency- doubling laser is 5 30 .2 nm,the lowest threshold energy is 2 m J,the hightestcon- version efficiency is 3.3% ,and the highest green laser energy 1 .0 3m J.The laser character- istics of Nd:YCOB self- frequency crystal are discussed.
