【摘要】 分析了飞秒激光啁啾脉冲放大系统(CPA)中的增益光谱窄化效应,讨论了抑制光谱窄化效应的有效方法,据此研制了几种飞秒脉冲光谱损耗元件。实验结果表明在CPA系统中常见的光谱窄化效应可以得到有效抑制,光谱展宽效果较好。
【Abstract】 Gain narrowing effect in the chirp pulse amplification of femtosecond laser is investigated. A few methods on overcoming gain narrowing are introduced, and some spectrum loss elements are produced. The experiments show that the gain narrowing in CPA system can be reduced and the spectrum broadening are achieved.
【Key words】 chirp pulse amplification of femtosecond laser; gain narrowing effect; spectrum broadening;
