We demonstrate burst-mode operation of a polarization-maintaining Yb-doped fiber amplifier. Groups of pulses with a temporal spacing of 10 ns and 1 kHz overall repetition rate are amplified to an average pulse energy of ∼20 μJ and total burst energy of 0.25 mJ. The pulses are externally compressed to ∼400 fs. The amplifier is synchronously pulsed-pumped to minimize amplified spontaneous emission between the bursts. We characterize the influence of pump pulse duration, pump-to-signal delay, and signal burst length.
我们展示了偏振保持掺镱光纤放大器的突发模式操作。具有 10ns 时间间隔和 1kHz 总重复率的脉冲组被放大到平均脉冲能量约为 20μJ 和总突发能量为 0.25mJ。这些脉冲被外部压缩到约 400fs。放大器采用同步脉冲泵浦，以最大限度地减少突发之间的放大自发辐射。我们研究了泵浦脉冲持续时间、泵浦到信号延迟和信号突发长度的影响。
