Abstract

The events of the birth and annihilation of optical vortices in topologically neutral nonparaxial combined mode beams (topological dipoles) were studied. It is shown that there exists an extended domain of parameters of the elementary beams, for which the optical vortices of the dipole annihilate near the focal plane, thus restoring a wave field free of the wavefront dislocations.
