INVERSE PROBLEM OF A LASER AMPLIFIER SYSTEM CONTAINING A SPATIAL FILTER
含空间滤波器的激光放大系统的逆问题

Starting from the Frantz-Nodvik equation and Huygens-Fresnel diffraction integral and using the fast Fourier transform and successive iteration method, we studied the inverse problem of a laser amplifier system containing a spatial filter, i-e-, to find the initial input temporal pulse profile, am-plitude and phase distributions from the required output temporal, spatial pulse profile and fluence, as well as the given amplifier and spatial filter parameters-
