Abstract

In this work, a compact fiber chirped pulse amplification system exploiting a tandem of a chirped fiber Bragg grating stretcher and a chirped volume Bragg grating compressor with matched chromatic dispersion is presented. Chirped pulses of 230 ps duration were amplified in a Yb-doped fiber amplifier and re-compressed to 208 fs duration with good fidelity. The compressed pulse duration was fine-tuned by temperature gradient along the fiber Bragg grating stretcher.

摘要

在这项工作中，提出了一种紧凑的光纤啁啾脉冲放大系统，该系统利用一个啁啾光纤布拉格光栅展宽器和一个具有匹配色散的啁啾体布拉格光栅压缩器串联而成。持续时间为230 ps的啁啾脉冲在掺镱光纤放大器中被放大，并以良好的保真度重新压缩至208 fs的持续时间。通过沿光纤布拉格光栅展宽器的温度梯度对压缩脉冲持续时间进行微调。
