摘　　要：对种子注入 KTP光学参量振荡器进行了实验研究。利用可调谐连续波钛宝石激光器作为种子注入源 ,以调 Q倍频 YAG激光器为泵浦源 ,在 76 0～ 82 0 nm的范围内获得了线宽小于 0 .0 2nm的可调谐参量光输出 ,最大输出能量达 4 m J,同时种子注入的阈值功率密度小于 0 .5W/cm2 。We have demonstrate a tunable near-infrared KTP optical parametric oscillator that uses the CW Ti∶sapphire laser output as the injection seeder and the second harmonic of a Q-switched Nd∶YAG as the pump source. The linewidth of the OPO was less than 0.02 nm and the OPO can be tuned from 760 to 830 nm. The threshold of the seeder′s power density was about 0.5 W/cm2.
