Two high pulse contrast (> 95 dB) polarization maintaining all-fiber amplifier chains were coherently combined to generate 0.42 mJ, 1 ns 25 kHz pulses with 79% efficiency despite 38 radians of intra-pulse phase distortion. A recursive intra-pulse phase compensation method was utilized to correct for the large nonlinear chirp providing a path for improved coherent waveform control of nanosecond pulse trains.
两个高脉冲对比度（>95分贝）的保偏全光纤放大器链被相干组合，以产生能量为0.42毫焦、脉宽为1纳秒、重复频率为25千赫的脉冲，尽管存在38弧度的脉冲内相位失真，效率仍达到79%。采用了一种递归脉冲内相位补偿方法来校正大的非线性啁啾，为改善纳秒脉冲序列的相干波形控制提供了一条途径。
