摘　　要：用全固态 10 6 4nm调Q激光输出 ,抽运多周期PPLN ,实现了宽调谐的准相位匹配光参变振荡。振荡阈值10 .3μJ(脉宽 2 2ns) ,信号光最高输出平均功率为 42 .5mW ,斜率效率为 12 .5 %A widely tunable quasi phase matched optical parametric oscillator was demonstrated by using periodically poled LiNbO 3 (PPLN) with a multigrating structure. With a 1064 nm acousto optically Q switched Nd∶YVO 4 pump laser, a tunable IR output from 1.436 μm to 1.7 μm was obtained. The threshold was 10.3 μJ with pulses repetition rate of 10 kHz. The maximum average output power of signal is 42.5 mW with pump to signal conversion efficiency of 12.5%.
