Abstract

A new integro-differential equation with the only first order derivative describing diffraction of arbitrary transversely nonuniform light beam in the homogeneous transparent medium is obtained. At first, it is introduced for the case of linear media. The ones approximation of the forward propagation is used (so the case of backward propagation is excluded). It is shown that derived equation in the case of light beams with the great diameter transforms to the well-known parabolic equation. The new approach is generalized also for the case of nonlinear media. Thus, the new truncated wave equation describing the diffraction of nonparaxial light beams in the nonlinear media is obtained.
