Double reflection and birefringence of a wave incident on the crystal boundary under the conditions of internal conical refraction

Abstract

It is shown that a cone of rays undergoing internal conical refraction generates reflected ordinary and extraordinary rays at the crystal boundary, which form cylindrical surfaces. The cylinders formed by ordinary and extraordinary rays are, respectively, circular and elliptical. At the same intensity of rays forming the cone of internal conical refraction, the intensity distributions over the generatrices of these cylinders are different. A similar situation occurs also for refracted rays if a crystal is adjacent to an anisotropic medium.
