Generation of optical vortices in rotating uniaxial crystal
for light propagation along the perpendicular to its optical axis
Taurida National University, Department of General Physics, 4, Vernadsky Ave., 95007 Simferopol, Ukraine, Phone: +38(066)574-73-02, e-mail: simplexx.87@gmail.com Abstract. We have experimentally considered evolution of the Gaussian beam propagating nearly perpendicular to the uniaxial crystal axis. Also we have analyzed the spin and orbital angular momenta and found oscillations of the angular momentum when the crystal optical axis is rotated. Keywords: angular momentum, singular beam, polarization, optical vortex, umbilics.
