Abstract
The Rytov approximation for wave propagation in random media is generalized to include the effects of self‐focusing. Solutions are obtained which show how the intensity fluctuations, which are either initially present in the wave or which are induced by the random inhomogeneities in the media, grow catastrophically. These solutions may be used to obtain conditions on the homogeneity of the medium, or of the incident beam, for reduction or elimination of catastrophic self‐focusing in the medium.Keywords
