报道了一种波长为1064 nm的单频准连续波部分抽运板条放大器。将4.4W单频种子激光器放大到148.1 W，光光效率为30.4%。输出脉冲宽度为141.4μ，重复频率为500 Hz。M2的光束质量因子在水平方向和垂直方向分别为1.41和1.37。实验结果与数值模拟结果吻合较好。据我们所知，这是第一次报道具有如此高输出功率和效率的单频Nd：YAGInnoslet放大器。
In this paper, a single-frequency quasi-continuous-wave partially pumped slab (Innoslab) amplifier at 1064 nm is reported. The 4.4-W single-frequency seed laser was amplified to 148.1 W with optical-optical efficiency of 30.4%. The output pulse duration was 141.4 μs at the repetition of 500 Hz. The beam quality factors of M2 were 1.41 and 1.37 in the horizontal and vertical direction respectively. The experimental results match well with the numerical simulation. To the best of our knowledge, this is the first report on single-frequency Nd:YAG Innoslab amplifier with such a high output power and efficiency.
