Head Volyar Alexsander Vladimirivich, Registration Date 12-03-2011 Organization National Taurida V. Vernadsky University popup.description2 A solution of the wave equation and the continuity equation of nonparaxial beams propagating obliquely to the optical axis of the anisotropic medium was found. 1. Nonlocal lateral shift of the beam axis had been calculated. An experiment to determine the magnitude of lateral shear monochromatic singular Laguerre-Gaussian beam propagating through a crystal LiNbO3 was held. 2. A solution for paraxial vector wave equation of diffracting and nondiffracting beams in pure birefringent medium and in pure optically active medium was found. Also the energy conversion efficiency of nonsingular beam into singular beam and backward was calculated. 3. A solution of the vector wave equation was found and spectra of the propagation constants of modes, optical fibers in the form of a spiral winding and twisting the birefringence axes was calculated. The window of transmittance and opacity for singular beams for such fibers was invented.
