Abstract

We report a novel implementation of chirped-pulse amplification (CPA) by dominantly using dispersive multilayer mirrors for chirp control. Our prototyp dispersive-mirror (DMC) compressor has been designed for a kHz Ti:sapphire amplifier and yielded--in a proof-of-concept study--millijoule-energy, sub-20-fs, 790-nm laser pulses with an overall throughput of approximately 90% and unprecedented spatio-temporal quality. Dispersive-mirror-based CPA permits a dramatic simplification of high-power lasers and affords promise for their advancement to shorter pulse durations, higher peak powers, and higher average powers with user-friendly systems.

摘要

我们报告了一种啁啾脉冲放大（CPA）的新型实现方式，主要通过使用色散多层镜来控制啁啾。我们的原型色散镜（DMC）压缩器是为千赫兹钛宝石放大器设计的，并且在一项概念验证研究中产生了毫焦耳能量、低于20飞秒、790纳米的激光脉冲，总吞吐量约为90%，时空质量达到了前所未有的水平。基于色散镜的CPA能够极大地简化高功率激光器，并有望推动其朝着更短脉冲持续时间、更高峰值功率以及更高平均功率的方向发展，同时构建出用户友好的系统。
