Abstract

An optical wave propagating in the turbulent atmosphere - a medium with sto- chastic variation of the permittivity - experiences intensity scintillations due to random deformations of its amplitude and phase. For the sufficiently long propagation paths the scintillations get saturated [1]. The experimentally observed effect of saturation has not yet be satisfactorily theoretically explained. An attempt is made here to tackle the problem using semisymbolical solution of the differential equation for the fourth statistical moment of the complex amplitude. 1 Governing equation Let us consider turbulent atmosphere - a medium with stochastic spatial and temporal variation of the permittivity e(/V), which can be written in the form
