Gérard Mourou received his PhD from Pierre and Marie Curie University in 1973. He and his student Donna Strickland co-invented chirped pulse amplification (CPA) technology and shared the 2018 Nobel Prize in Physics. This technology made it possible to apply ultrafast lasers to many new areas, such as eye surgery, precision manufacturing, particle physics and nuclear fusion. Gérard Mourou is the founding Director of the Center for Ultrafast Optical Science (CUOS) at the University of Michigan and the initiator of the Extreme Light Infrastructure (ELI) in Europe.

本文介绍了一种基于圆偏振光脉冲驱动的波长可调谐、能量可扩展的超快光纤光源。在光子晶体光纤中利用自相位调制占主导的非线性效应来展宽脉冲光谱，在输出端使用滤光片来选择特定的光谱旁瓣以满足后续实验需要。仿真及实验表明：在光谱展宽程度相同时，输入的圆偏振光功率需要达到线偏振光功率的1.4倍，相应的滤出光谱旁瓣能量约为线偏振光的1.4倍。进一步研究表明：圆偏振脉冲的输出光谱普遍存在比线偏振脉冲输出光谱更清晰的波瓣结构，有利于后续滤波输出过程中脉冲质量的提升；适当增加脉冲的输入功率可进一步拓宽光谱的调谐范围，在输入功率为4.9 W时，可获得波长范围为930~1200 nm的高能量飞秒脉冲。

We report a high power fiber amplifier based on nonlinear chirped-pulse amplification (NCPA). To manage the nonlinearity, pulse shaping is introduced by self-phase modulation in the fiber stretcher with the help of spectral filtering. The third-order dispersion is compensated for by the nonlinear phase shift in the NCPA. With optimization, the system can output 382 fs pulse duration with 20 W average power at 1 MHz repetition rate. The long-term average power fluctuation is measured to be 0.5% in 24 h, and the beam quality factor () is 1.25.
