The ins and outs of conical refraction
patriotic pride, who called conical refraction “the radiant stranger” in a florid passage in his memoirs. The two physicists responsible for the theoretical prediction and experimental confirmation of conical refraction were William Rowan Hamilton (1805-1865) and Humphrey Lloyd (1800-1881), both professors of Trinity College Dublin (fig. 1). Ireland’s recent Year of Hamilton (2005) provided an ...
متن کاملOn Conical Refraction in Hexagonal and Cubic Media
The occurrence of conical refraction in hexagonal and in cubic elastic media is investigated by the method of localizations. This is accomplished by generalizing the Atiyah–Bott– G̊arding theory from the scalar case to hyperbolic square systems of linear partial differential systems with constant coefficients.
متن کاملInternal conical refraction of light beams in biaxial gyrotropic crystals
Internal conical refraction in biaxial gyrotropic crystals has been studied theoretically. A special case of Gaussian beam conical refraction has been considered comprehensively. The results of numerical simulation agree well with the available experimental data. 2002 Elsevier Science B.V. All rights reserved. PACS: 42.25.Bs; 42.25.Lc; 42.25.Fx; 78.20.Ek; 78.20.Fm
متن کاملConical diffraction complexified: dichroism and the transition to double refraction
With dichroism (anisotropic absorption), the dielectric tensor of a crystal becomes non-Hermitian, and each optic axis (diabolical point) splits into two singular axes (branch-point degeneracies). For a Gaussian beam incident on a dichroic crystal in a direction near the singular axes, the polarized light beyond the crystal is given by the same diffraction integrals as for a transparent crystal...
متن کاملWave-vector and polarization dependence of conical refraction.
We experimentally address the wave-vector and polarization dependence of the internal conical refraction phenomenon by demonstrating that an input light beam of elliptical transverse profile refracts into two beams after passing along one of the optic axes of a biaxial crystal, i.e. it exhibits double refraction instead of refracting conically. Such double refraction is investigated by the inde...
