Vortexless and self-converging optical traps

The possibility of the vortexless optical traps and self-converging optical traps formation on the base of technique of computer generated holograms is considered. Two methods of the creation of self-converging optical traps are proposed. First of them is based on the transforming of the vortexless optical trap. The second of them is based on the formation of special kind of elementary polarization singularities. The principles of the formation of s-contours with optimal characteristics are formulated. The results of computer simulation and experimental modeling are presented.
