Abstract
Stationary properties of high intensity wave beams in weakly inhomogeneous media with a saturable nonlinearity are investigated by means of a consiste nt asymptotic method It is shown that the strongest effects of the nonlinea rity are most important within a certain range of the medium parameters and explicit formulas for the beam intensity and the beam phase velocity are o btained in this range. The existence of bistable beam states is also discus sed.
