Incorporation of coherent combination into a state-of-the-art fiber-chirped pulse amplification system obtains 1.1 mJ, 340 fs pulses with up to 280 W of average power at 250 kHz repetition rate. Propagation of this laser pulse inside a krypton-filled hollow-core fiber results in significant spectral broadening. Chirped mirrors are used to compress the pulses to 26 fs, 540 μJ (135 W) leading to a peak power of more than 11 GW. This unprecedented combination of high peak and average power ultrashort pulses opens up new possibilities in multidimensional surface science and coherent soft x-ray generation.
将相干合成技术纳入最先进的光纤啁啾脉冲放大系统中，可在 250 kHz 的重复率下获得 1.1 mJ、340 fs 的脉冲，平均功率高达 280 W。这种激光脉冲在充满氪气的空芯光纤中传播会导致显著的光谱展宽。啁啾反射镜可将脉冲压缩至 26 fs、540 μJ（135 W），峰值功率超过 11 GW。这种前所未有的高峰值和平均功率超短脉冲的结合，为多维表面科学和相干软 X 射线的产生开辟了新的可能性。
