As known, lasers are used for atmospheric communication. There are advantages of an optical wave system over a radio frequency system. But there arise a number of problems in that case. Turbulent fluctuations of density in the atmosphere cause various deteriorative effects on signals. We investigated the propagation of the non-paraxial Gaussian beam through air inhomogeneity. The refractive index of air can be written in the form: 1 n 1 n , 1 n being a small quantity. In this case we can find the solution of the Maxwell equations. The paper represents results of computations for a model inhomogeneity.
