Abstract

Nonlinear equation of amplitude-phase optical wave fluctuations in a randomly inhomogeneous medium is considered. The solution of the set of equations is obtained from integration along the vector characterization. In a small-angle approximation, the vector characterization is a normal to the phase front, therefore, it is called amplitude-phase ray (or ray, only). A nonlinear integral-differential equation is obtained for the average amplitude-phase ray in a turbulent-medium propagating Gaussian optical beam. It is shown that the average amplitude-phase ray agrees with the paraxial approximation for the average diffraction ray.
