Abstract: In this paper,starting from triangle expressions of complex parameters and Fresnel number of Gaussian beam,the method of complex fraction linear transformation is employed to derive the similar geometrical optics formula of Gaussian beam' complex parameter transformation.The conceptions of conjugation,exchange and inverse evolve point pair are used to explain the transformation properties of Gaussian beam.
