实验上采用纳秒级窄线宽脉冲钛宝石激光注入BBO光参量放大器 (BBO OPA) ,实现了一台纳秒级Nd∶YAG激光器作钛宝石激光器和BBO光参量激光器抽运源的高效率系统。获得了钛宝石激光作为信号光注入BBO OPA时其输出能量为无信号光注入时的 6倍 ,并实现了 5 70～ 6 70nm的连续可调谐窄线宽 (<0 1nm)参量激光输出
Experiments have been carried out on BBO OPA using a nanosecond narrow-line-width pulsed Ti: sapphire laser to realize a high-efficiency system with a nanosecond-level Nd:YAG laser as the source of pumping of the Ti: sapphire laser and the BBO optical parametric laser . The results showed that the output power of Ti: sapphire laser was 6 times higher than that of no signal light when BBO OPA was injected into the BBO OPA, and the CW tunable narrow linewidth (<0 1 nm) of 5 70 ~ 6 70 nm was achieved.
