The diffraction of Gaussian vortex beams in uniaxial crystals orthogonal to the optical axis is studied. Analytical expressions for the components of the diffraction field are derived and illustrated by numerical examples. Results indicate that, upon diffraction of Gaussian vortex beams inside uniaxial crystals, components of the transversal and longitudinal electric fields would vary and show different characteristics. Effects of anisotropic crystals on intensity distributions of Gaussian vortex beams are also investigated. It demonstrates that, upon diffraction, intensity distributions would be distorted and rotated into elliptical profiles with the variation of the ratio of refractive indices. These influences may finally cause the non-symmetry of the intensity distributions of laser beams.
