我们展示了在充氩气的中空光纤中使用感应相位调制和自相位调制产生的超宽带白光连续谱的首次脉冲压缩。通过液晶空间光调制器的反馈啁啾补偿和用于直接电场重建的改进的光谱干涉测量法，在可见光到近红外区域生成2.6-fs、1.4-GW、1.3周期变换限制脉冲。
We demonstrate the first pulse compression of ultrabroadband white-light continuum generated using both induced- and self-phase modulations in an Ar-gas-filled hollow fiber. By feedback chirp compensation with a liquid crystal spatial light modulator and a modified spectral interferometry for direct electric-field reconstruction, 2.6-fs, 1.4-GW, 1.3-cycle transform-limited pulses are generated in the visible to near-infrared region.
