摘　　要：采用光纤耦合输出激光二极管阵列端面抽运Nd:YVO_4晶体,采用"8"字环形腔,在腔内插入法拉第旋光器和半波片实现激光的单向运转以抑制空间烧孔效应,并选用二类临界相位匹配的KTP进行腔内倍频,获得了输出功率为2.6W,波长为532nm的单频绿光,光-光转换效率为12.1%。An Nd： YVO4 crystal is end-pumped by a fiber-coupled laser diode array. The ＂8＂ shaped ring resonator with a Faraday rotator and a half wave plate is applied to eliminate the spatial hole-burning effect. Using a type II KTP as the intracavity frequency doubled crystal,2.6W green laser of single-frequency at 532nm is obtained, and the optical-optical conversion efficiency is 12. 1%.
