我们展示了通过自相位调制来增加入射到中空光纤上的能量以进行光谱展宽的方法。我们使用啁啾脉冲进行光谱展宽，降低了光强度，以避免气体介质的电离。我们还使用氦作为非线性介质，利用压力梯度中空光纤脉冲压缩器，以1 kHz的重复频率产生了5.0ps、5.0mJ的脉冲。(C)2010年美国光学学会
We demonstrate methods to increase the energy incident on hollow fibers for spectral broadening by self-phase modulation. We used chirped pulses for spectral broadening, lowering the optical intensity to avoid ionization of the gaseous medium. We also used helium as a nonlinear medium and demonstrated the generation of 5.0 fs, 5.0 mJ pulses at a repetition rate of 1 kHz using a pressure gradient hollow-fiber pulse compressor.
