摘　　要：采用双Nd∶YAG棒串接加90°旋光器补偿热致双折射,双声光Q开关调制,LBO晶体腔内倍频,实现了532 nm准连续绿光输出。重复频率10 kHz时,532 nm绿光输出功率达69 W,脉宽200 ns。重复频率15 kHz时,532 nm绿光输出功率达71 W,脉宽250 ns,倍频转换效率57.5%。An all-solid-state quasi-continuous-wave（QCW） green laser was developed by use of plane-plane cavity with tow-rod birefringence compensation technology,LBO crystal was used for second harmonic generation.Two orthogonal acousto-optic Q-switches were used to sustain fully holding of the pump gain.120 W at 1064 nm wavelength was achieved when the repetition rate was 15 kHz,and the 532 nm average output power is 71W with a pulse width of 250 ns and a conversion efficiency of 57.5% from the 1064 nm light to the green laser.The 532 nm average output power is 69W at a repetition rate of 10 kHz and a pulse width of 200 ns.
