We demonstrate the generation of nanosecond and multikilowatt peak-power pulses in a double-clad Yb-doped fiber amplifier seeded by a spectrally narrowed gain-switched laser diode. Injected pulses with 100 ns duration were simultaneously compressed and amplified by the combination of high amplifier gain and stimulated Brillouin scattering. A maximum peak power of 20 kW has been obtained, corresponding to a single-pass gain of +57 dB in terms of peak power. Part of this output signal was also converted into IR continuum light by splicing a length of single-mode fiber at the end of the fiber amplifier.
我们展示了在由光谱窄化增益开关激光二极管种子的双包层 Yb 掺杂光纤放大器中产生纳秒和千瓦峰值功率脉冲的情况。通过高放大器增益和受激布里渊散射的组合，对持续时间为 100ns 的注入脉冲进行同时压缩和放大。获得了 20kW 的最大峰值功率，这相当于以峰值功率计的单通增益为 +57dB。光纤放大器末端熔接一段单模光纤，将部分输出信号转换为红外连续光。
