Abstract
A modification of model describing optical structures forming in nonlinear ring interferometer (NRI) containing liquid crystal having Kerr effect is suggested. Case of optical field which is turned through some angle in cross section plane of the laser beam (in feedback of the NRI) is investigated. It is found that both screw dislocation order of the wavefront entering on the NRI input and phase shift of the optical field in circuit of feedback of the NRI effects on optical forming process equally strong. A theoretical analysis and simulations show any new possibilities of NRI applications: the identification of spiral dislocation order of an optical vortex (by shape of optical structures self-organizating in cross section plan of laser beam in NRI); the compensation of the optical vortex effect on evolution and result of the optical forming in NRI; basis of an arithmetic-logical optical device realizing addition operation.
