非线性相位调制高斯光束的衍射积分简化计算

A SIMPLE CALCULATING METHOD OF THE DIFFRACTION OF NONLINEAR PHASE MODULATED GUSSIAN BEAM

从理论上给出一种类似于采样原理简化衍射积分的方法，对于非线性相位调制高斯光束，积分可以简化为级数求和，计算时间有两个数量级减少。

We study a simple method of the diffraction calculation of nonlinear phase modulated Gaussian beam.Due to the local distribution of the field,the integral is substituted by the sum of series and a lot of time is saved.
