Annotation
Path integration is used with the given-channel approximation to examine the propagation of a beam with random phase modulation in a medium having local and nonlocal nonlinearities. It has been found that the beam radius and the correlation radius vary in the same way. In the case of a self-focusing medium, an expression is obtained for the critical power for waveguide propagation.
