摘　　要：基于Ｆｒａｎｔｚ－Ｎｏｄｖｉｋ（Ｆ－Ｎ）方程和广义惠更斯－菲涅耳衍射积分，提出了解决含空间滤波器的多程激光放大系统的逆问题的迭代算法，并作了数值计算。所得的数值计算方法和有关结果可用于高功率多程激光放大系统的设计。Based on the Frantz Nodvik equation and Huygens Fresnel diffraction integral, an successive iteration method has been presented to solve the inverse problem of a multipass laser amplifier system containing a spatial filter. Numerical caculations have been performed. The numerical calculatior method and results obtained can be used to design high power multipass laser amplifiers.
