| Abstract: | In this paper, the properties of Gaussian beams are described in complexplane, and the methods of complex fraction linear transformation and geometrical inverse evolvepoint pair are employed to research the transformation propertics of Gaussian beams, a few ofsimilar Newton's formula and similar gassy formula of saussian beams which seometrical opticalise are derived, and the natural of Fresnel number and focal shift concept in Gaussian beamsare expounded. |
