摘要
从FrantzNodvik方程和广义惠更斯菲涅耳衍射积分出发,采用快速傅里叶变换和逐次逼近叠代法,求解含空间滤波器的激光放大系统的逆问题,即由所要求的输出激光时间、空间波形和能量密度,并给定放大器和空间滤波器参数情况下,求输入激光时间波形、振幅和相位分布.
Abstract 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, amplitude and phase distributions from the required output temporal, spatial pulse profile and fluence, as well as the given amplifier and spatial filter parameters.
