摘要
对飞秒脉冲放大中通过整形种子脉冲光谱补偿增益窄化效应的过程进行了数值模拟 ;对比研究了普通种子脉冲放大过程和整形种子脉冲放大过程中的光谱增益特性 ;定义了带宽窄化率 ;讨论了初始啁啾量对注入种子脉冲及增益窄化效应的影响 .计算结果表明
Numeric simulation of compensating gain\|narrowing in femtosecond Ti:sapphire amplifier by shaping seed pulse is made in this paper,the gain spectral narrowing process are compared for multipass amplifiers with general and shaping seeding pulses injection respectively.On this base,we define the band width narrowing ratio,the simulation results show the gain\|narrowing effect can be well overcome by shaping laser pulses from oscillator.
