We demonstrate a high-stimulated-Brillouin-scattering-threshold monolithic pulsed fiber laser in a master oscillator power amplifier configuration that can operate over the C band. In the power amplifier stage, we used a newly developed single-mode, polarization maintaining, and highly Er/Yb codoped phosphate fiber with a core diameter of 25 microm. A single-frequency actively Q-switched fiber laser was used to generate pulses in the hundreds of nanoseconds at 1530 nm. We have achieved peak power of 1.2 kW for 105 ns pulses at a repetition rate of 8 kHz, corresponding to a pulse energy of 0.126 mJ, with transform-limited linewidth and diffraction-limited beam quality.
我们演示了一种在主振荡器功率放大器结构中具有高受激布里渊散射阈值的单片脉冲光纤激光器，该激光器可以在 C 波段工作。在功率放大器级，我们使用了一种新开发的芯径为 25 微米的单模、偏振保持、高掺铒/掺镱磷酸盐光纤。我们使用单频主动 Q 开关光纤激光器在 1530nm 处产生数百纳秒的脉冲。我们已经实现了重复率为 8kHz 的 105ns 脉冲的峰值功率为 1.2kW，对应于 0.126mJ 的脉冲能量，具有变换极限线宽和衍射极限光束质量。
