摘　　要：针对高次谐波稳定性差的问题,采用再生锁模控制的方法。首先分析锁模脉冲的形成机制,接着对光频率进行合成,经三波瞬态耦合波方程,最后得到高次谐波。在实验装置中得到均衡的脉冲图像且锁模脉冲平滑,获得高信噪比和高稳定性放大的信号光,因此增加光参量啁啾脉冲放大系统的灵活性,本文所采用的分析方法对其他光源的稳定设计也有借鉴作用。To improve the stability of the high order harmonic components,regeneration mode locking control is used as a solution.Firstly the formation mechanism of the mode locking pulse is analyzed.Then optical frequency synthesis is made based on three wave transient state coupling equation.Finally the high order harmonic components are obtained.In the experiment,pulse image obtained is balanced and the mode locking pulses are smooth.High signal-tp-noise ratio and high stable amplified light is obtained,which increases the quality and flexibility of chirp pulse amplifying system.The analysis method presented can be also applied to the design of other stable light source.
