LD泵浦Nd：YVO_4内腔倍频激光器获得120mW绿光连续输出

CW 120mW Greem Laser Output from Intracavity Doubling Diode-pumped Nd:YV4 Laser

利用半导体激光器（ＬＤ）端面泵浦Ｎｄ：ＹＶＯ＿４和用ＫＴＰ内腔倍频的绿激光器获得了１２０ｍＷ连续、稳定的５３２ｎｍ绿激光输出。泵浦阈值Ｐ＿（ｔｈ）＝１６０ｍＷ，光－光转换效率η＿ｓ＝８．１％。换用激光腔输出耦合镜，在不加ＫＴＰ晶体倍频时，可连续输出１．０６μｍ的红外激光，输出功率为４５０ｍＷ，光－光转换效率为３１％。

It is reported that a CW120mW green laser output of an intracavity doubling and diode- pumped Nd:YVO4 green laser at 532nm is obtained(pumping threshold Pth=160mW,slope efficiency ηs= 8.1/)。Also,a CW450mW output at l.06μmis gained when the laser output mirror is changed(slope efficiencyis 3l%)。
