Abstract
The laser-induced conical emission of radiation in Kerr medium, caused by the process of spatial self-phase modulation, has been investigated experimentally. The experiment was realized for the conditions, when large self-phase modulation was acquired in the absence of self-focusing, which drastically distorts the beam intensity distribution. The first observation of this effect in liquid crystal using cw laser radiation was performed in Ref. 1. This effect is not observed in a Kerr medium. The interest to the present investigation is connected also with the possibilities to use the effect of spatial self-phase modulation for diagnostics of photon statistics, predicted in Ref. 2 for Kerr media.
