Abstract

We demonstrate generation of 3.8-fs pulses with energies of up to 15 microJ from a supercontinuum produced in two cascaded hollow fibers. Ultrabroadband dispersion compensation was achieved through a closed-loop combination of a spatial light modulator for adaptive pulse compression and spectral-phase interferometry for direct electric-field reconstruction (SPIDER) measurements as feedback signal.

摘要

我们展示了从两根级联空心光纤中产生的超连续谱产生能量高达15微焦的3.8飞秒脉冲。通过将用于自适应脉冲压缩的空间光调制器与用于直接电场重建（SPIDER）测量的光谱相位干涉测量作为反馈信号进行闭环组合，实现了超宽带色散补偿。
