我们提出并证明了一种脉冲压缩技术，使用中空纤维的压力梯度。这种技术提高了飞秒激光脉冲的空间和光谱质量的光谱展宽的自相位调制，并允许脉冲压缩的脉冲能量的增加。利用啁啾镜进行色散补偿，我们成功地将脉冲压缩到小于10 fs，能量高达5 mJ。
We propose and demonstrate a pulse compression technique using a hollow fiber with a pressure gradient. This technique improves the spatial and spectral qualities of femtosecond laser pulses spectrally broadened by self-phase modulation, and allows an increase of the pulse energy for pulse compression. Using chirped mirrors for dispersion compensation, we have successfully compressed the pulse to less than 10 fs with an energy as high as 5 mJ.
