摘　　要：报道了采用窄线宽脉冲钛宝石激光器作种子注入的ＢＢＯ光学参量振荡激光器，并且整个系统只使用一台Ｎｄ：ＹＡＧ激光器．其中钛宝石激光的泵源为Ｎｄ：ＹＡＧ三倍频（ＯＰＯ的泵浦光）后剩余的二倍频．不额外消耗能量，所以整个激光系统效率较高．现有泵浦条件下．信号波能量转换效率达２５％．并实现了５８９～８９２ｎｍ的连续可调谐窄线宽（＜０．０１ｎｍ）激光输出。We report on a β- barium borate(BBO)optical parametric oscillator injectionseeded with a narrow bandwidth pulsed Ti:sapphire laser.This device is pumped by onlyone Nd: YAG laser.The pump source of the Ti:sapphire laser is the residual secondharmonic(532 nm) in frequeney-tripling(355 nm,OPO's pump source)of the Nd: YAGlaser.As the Ti:sapphire laser does not consume other energy,thus the overall energyconversion efficiency is high.The signal coversion efficiency is up to 25%, and a narrowbandwidth (<0. 01 nm) continuous tunning range of 589￣892 nm is achieved.
