Abstract
This paper presents a brief review of theoretical and experimental studies of the structural and polarization conversion of laser beams in anisotropic crystals. The feasibility of creating laser beams with complex polarization-phase state is discussed. It is shown that adaptive tuning of structural and polarization-phase states can be carried out by relatively slow changes in the parameters of the optical system and fast high-speed electro-optical modulation methods.
