A simple, robust and compact pulse compressor for a high-repetition rate high-peak power fiber chirped pulse amplification system is presented. We use noble-gas-filled hollow fibers for spectral broadening of the optical pulses via self-phase modulation. Subsequent compression with chirped mirrors shortens the pulses by more than a factor of 10. Pulses shorter than 70 fs with pulse energies of the order of 100 mu J have been obtained resulting in a peak power up to 1 GW at 30.3kHz. Additionally, nonlinear polarization rotation has been used for temporal pulse cleaning during the nonlinear compression at 30.3 kHz and 100 kHz, respectively.
介绍了一种用于高重复率、高峰值功率光纤啁啾脉冲放大系统的简单、坚固且紧凑的脉冲压缩器。我们使用充有惰性气体的空心光纤，通过自相位调制实现光脉冲的光谱展宽。随后用啁啾镜进行压缩，使脉冲缩短了10倍以上。已获得脉宽短于70 fs、脉冲能量约为100 μJ的脉冲，在30.3 kHz时峰值功率高达1 GW。此外，分别在30.3 kHz和100 kHz的非线性压缩过程中，利用非线性偏振旋转进行脉冲的时域清洗。
