Abstract

Using a multi-variable series method, we successfully investigated the global property of perturbation description for fundamental Gaussian beam. We explicitly proved that as long as the perturbation parameter s≠0, although it includes the Gaussian factor $\exp(-\frac{\rho^{2}}{4\zeta^{2}+1})$ ( ρ and ζ are normalized cylindrical polar coordinates defined in the text), the complete perturbation solution for fundamental Gaussian beam always diverges.
