摘　　要：研究了一种基于周期极化掺镁铌酸锂(PPMgLN)晶体做倍频器件的新型、紧凑和高功率连续绿光激光器。利用外加电场极化法成功制备了厚度为1 mm,短周期为6.95μm,占空比接近50%,大面积均匀的PPMgLN;在6.8 W单管激光二极管(LD)抽运的情况下,利用通光长度仅1 mm的PPMgLN,腔内倍频获得了3.8 W的绿光532 nm激光输出,光-光转换效率高达56%。A compact and highly efficient green-light source is demonstrated based on periodically poled Mg：LiNbO3（PPMgLN） crystal.The MgO：LiNbO3 samples of 1 mm thick,6.95 μm domain period,uniform periodicity,near 50% duty cycle are fabricated by use of a high-voltage multi-pulse poling method.A maximum power of 3.8 W at 532 nm is obtained by a 6.8 W laser diode（LD） pumped,the PPMgLN length in Nd：YVO4 intracvity is only 1 mm,and the corresponding optical to optical conversion efficiency is 56%.
