Research of interference of sharp-focused oncoming beams with different polarizations

We consider formation of three-dimensional distributions of intensity by means of interference of sharp-focused oncoming vortex beams with different polarization. It is shown, that at use of the narrow ring aperture the chain of repeating configurations is formed along the optical axis. The form of these configurations can be changed by polarization and phase structure. When Gaussian beams are used it is possible to form the three-dimensional distributions possessing spherical symmetry depending on polarization, the vortex order and additional phase.
