Abstract

The effect of internal conical refraction in biaxial crystals is applied for transforming the lowest-order Gaussian laser beams into optical vortex beams and annular beams with radial and azimuthal polarization. The evolution of the emerging vortex beams upon propagation is analyzed and compared with the reference Laguerre-Gauss beam. The formation of beams with radial and azimuthal polarization with the aid of two biaxial crystals placed into the arms of a Mach-Zehnder interferometer is demonstrated.
