Optical singularities are induced in Gaussian laser beams by Kerr-like medium: geometrical optics study

摘要

The geometrical optics method permits to make preliminary conclusions about optical singularities formation and their location after specific phase object: the necessary and sufficient conditions of optical singularities existence are worked out. It was shown that the locus of optical singularities after thin Kerr-like medium shaped enclosed curves. The result agree with experiment and numerical modeling of wave equation.
