Paper Abstract

We report the nucleation of wave front phase dislocations in a Gaussian beam with initially smooth wave front experienced the self-action in a nematic liquid crystal cell. It is shown experimentally that the structure of the aberrational rings appeared due to inducing of a nonlinear lens in liquid crystal bulk has more complicated character than mentioned earlier.
