摘　　要：建立了多通式飞秒激光放大系统动力学过程的物理模型,该模型对其动力学过程中能量积累和能量抽取两个阶段的物理过程进行了理论描述,并结合具体的实验进行了数值模拟,获得了多通式飞秒激光放大过程中飞秒光脉冲能量、波形与各个参数之间的关系.与实验结果进行了比较,取得了较为一致的结果.We present a physical model which describes the kinetic process of femtosecond laser amplifier. We analyzed energy accumulation and abstract of the mechanic process in our physical model. In dependence of this, a mathematical treatment is developped to get relations between femtosecond pulse energy pulse shape and some experimental parameters. By comparing our calculated results with our experimental results, we have gotten satified results.
