摘　　要：用激光二极管(LD)抽运Nd∶YVO4晶体,采用四镜环形腔结构,腔内放置由法拉第旋光器,λ/2波片及布氏片组成的光学单向器,利用KTP内腔倍频技术,实现了高输出单频Nd∶YVO4绿光激光器及稳定的单频激光输出。在9 W的泵浦功率下,最大单频绿光输出为1.1 W,光-光转化效率为12.2%。在腔内插入Cr4+∶YAG晶体,又获得了脉宽为100 ns,重复频率为21 kHz的单纵模被动调Q激光输出。A frequency-stability and intracavity frequency-doubled ring Nd ＂ YVO4/KTP laser endpumped by a laser diode was designed and experimentally demonstrated. The laser was single-frequency operated by using a TGG, a Brewster polarizer, and a half-wave plate acted as optical diode in the cavity. Under the incident power of 9 W, the maximum green laser output is 1. 1W, and conversion efficiency from light to light is 12.2%. Also,a passively Q-switched single-frequency laser in laser pulse duration of 100 ns and repetition rate of 21 kHz was achieved in a ring cavity by inserting a piece Of Cr^4＋ ： YAG as an intracavity laser pulse saturable absorber.
