啁啾脉冲放大系统中光栅展宽器的性能与实验研究
Study on Single-Grating Strecher in Chirped-Pulse Amplification
摘要
论述了啁啾脉冲放大技术中运用单光栅展宽器结构将飞秒光脉冲在时域进行啁啾展宽的原理及特性,导出了该展宽器所提供色散量的具体表达式及其展宽后激光脉冲宽度的计算;然后通过数值计算分析了其展宽因子及展宽比随各参量的之间的变化关系;本文在此基础上进一步获得了实验上的测量结果。并进行了实验验证。
Abstract
A single grating pulse strecher in chired pulse amplification is demonstrated. To explain its pricinple of streching, we get a formula of dispersion and streching factor. Through the numerical analysis, the relationship between the streching factor and its related parameters, and the change of temporal duration of laser pulses streched by pulse strecher are discussed.
