We report on a high-power fiber frequency comb exhibiting linear chirped-pulse amplification up to 80 W and generating 120 fs pulses. By proper matching of the group delay between the fiber stretcher and compressor, a compression ratio of 3100 could be achieved. Carrier envelope offset self-referencing and long-term phase locking to an rf reference is demonstrated, exemplifying the suitability of this system for generating vacuum and extreme-UV frequency combs via enhancement in passive cavities and high harmonic generation.
我们报告了一种高功率光纤频率梳，其实现了高达 80 W 的线性啁啾脉冲放大，并产生了 120 fs 的脉冲。通过适当匹配光纤拉伸器和压缩器之间的群延迟，可以实现 3100 的压缩比。通过载波包络偏移自参考和对射频参考的长期相位锁定，证明了该系统适合通过在无源腔中增强和高次谐波产生来产生真空和极紫外频率梳。
