We report the realization of a frequency doubled, actively Q-switched and polarized oscillator based on Nd:YAG single-crystal fiber. A laser output of 8 W, 10 kHz, and 30 ns at 946 nm is reported. The laser is extracavity frequency doubled in a BiBO crystal to obtain 3 W and 300 μJ of blue laser with a beam quality of M(2)y=1.12 and M(2)x=1.38. The obtained blue power is stable with a root-mean-square stability of less than 2% in 1 h. This is more than two times the previously reported average power and energy at 473 nm.
我们报告了一种基于 Nd:YAG 单晶光纤的倍频、主动调 Q 和偏振振荡器的实现。报道了在 946nm 处输出功率为 8W、重复频率为 10kHz、脉宽为 30ns 的激光。该激光在 BiBO 晶体中进行外腔倍频，获得了 3W 和 300μJ 的蓝光激光，光束质量 M(2)y=1.12 和 M(2)x=1.38。在 1 小时内，获得的蓝光功率稳定性小于 2%，这比之前报道的 473nm 处的平均功率和能量高两倍以上。
