Paper Abstract

Until the present time it is commonly supposed that optical vortices (screw or edge wavefront dislocations) are generated either by natural or artificial phase nonuniformity (phase masks, compute-generated holograms, optical edges and so on) located on a light beam way (or inside a laser cavity). A nonuniformly polarized beam is regarded as a field with a fine wave structure, bearing vector singularities such as disclinations, C-lines and L-surfaces without connection with optical vortices. Nevertheless, as it will be shown later on the fine polarization field structure can be transformed under certain conditions into typical phase singularities - optical vortices and vice versa. Moreover, the energy efficiencies of these transformations are considerably higher and constructions of corresponding devices are more simpler than those connected with the usual vortex generation. The aim of the given paper is experimentally and theoretically to study a singular field structure of a light beam after the single-axis crystal in order to reveal the physical mechanism of polarization and phase transformations.
