Laser-Induced Nonlinear Gaussian Lens in Liquid Crystal Cell Gives Birth to Optical Vortices

For the first time we report the study of self-induced nonlinear lens in a liquid crystal cell with azo dye and the phase dislocations on a wave front of the beam passing through the lens. Depending on the experimental conditions, circular edge dislocation or optical vortices pairs may be created on...

Description
Summary:For the first time we report the study of self-induced nonlinear lens in a liquid crystal cell with azo dye and the phase dislocations on a wave front of the beam passing through the lens. Depending on the experimental conditions, circular edge dislocation or optical vortices pairs may be created on the wave front.
