采用Nd：YAG/YAG/Cr ~（4+）：YAG/YAG/YAG复合晶体和LBO晶体，首次实现了被动调Q倍频473 nm蓝光激光输出。实验结果表明，该系统的斜率效率达到18%，是目前所报道的被动调Q 473 nm激光系统中斜率效率最高的。在抽运功率为8.64 W时，获得了最大平均功率为0.93 W，脉宽为78 ns，重复频率为18.5 kHz的激光输出。
An Nd:YAG/YAG/Cr4+:YAG/YAGNd:YAG/YAG/Cr4+:YAG/YAG composite crystal and an LBO crystal were used to generate a passively Q-switched frequency-doubling 473 nm blue laser for the first time, to the best of our knowledge. The result demonstrated that the slope efficiency of this system reaches 18%, which is the highest in all the passively Q-switched 473 nm laser systems reported, to the best of our knowledge. Under the pumped power of 8.64 W, the maximum average output power of 0.93 W was obtained with a pulsewidth of 78 ns, and the repetition rate of 18.5 kHz.
