WebPhysics Journal of Optics We present a formalism able to predict the transformation of light beams passing through biaxial crystals. We use this formalism to show both theoretically and experimentally the transition from double refraction to conical refraction, which is found when light propagates along one of the optic axes of a biaxial crystal. http://www2.optics.rochester.edu/workgroups/lukishova/QuantumOpticsLab/homepage/Lecture_Phase_Matching-Sept_27_2010.ppt
