抽象的。我们报告了一款紧凑型 130W 单级主振荡器功率放大器，具有 51.3 kW 的高峰值功率和 0.1 nm 的窄光谱线宽。种子源是单模、被动锁模固态激光器，波长为 1064 nm，平均功率为 2 W。重复率为 73.5 MHz 时，脉冲持续时间为 30 ps。放大后，它延伸至 34.5 ps。实验使得光光转换效率达到75%。据我们所知，这是基于连续波锁模固态播种激光器的高功率、窄光谱线宽、高峰值功率皮秒脉冲光纤放大器的首次报道。当泵浦增加时，没有观察到放大的自发发射和受激拉曼散射。
Abstract. We report a compact, 130-W single-stage master oscillator power amplifier with a high peak power of 51.3 kW and a narrow spectral linewidth of 0.1 nm. The seed source is a single-mode, passively mode-locked solid-state laser at 1064 nm with an average power of 2 W. At a repetition rate of 73.5 MHz, the pulse duration is 30 ps. After amplification, it stretches to 34.5 ps. The experiment enables the optical-to-optical conversion efficiency to reach 75%. To the best of our knowledge, this is the first report of such a high-power, narrow spectral linewidth, high peak power picosecond-pulse fiber amplifier based on a continuous-wave, mode-locked solid-state seeding laser. No amplified spontaneous emission and stimulated Raman scattering were observed when the pump was increased.
