摘　　要：本文在一般情况下推导出超高斯光束是折射率梯度光纤中ＳＶＡ近似下波动方程的本征解并给出了折射率分布函数In general case,super Gaussian beam is not the solutions of Helmholtz equation and approximation condition of SVA.But ,by means of varying the distribution of refractive index of transmitting medium,super Gaussian beam could be the eigensolutions of Helmholtz equation.This paper proved that super Gaussian beam is the eigensolution of wave equation in GRIN fiber, and derived the distribution function of refractive index.As the special examples of this paper,the cases of literature and power law refractive index distribution are discussed.
