Abstract

We have combined Brillouin scattering experiments with a single Fabry-Perot interferometer and a fundamental optics theory to determine the birefringence of single crystals. Double refraction in anisotropic materials give rise to doublet peaks in Brillouin spectra. With the incident plane orthogonal to the optic axis, the birefringence of the materials can be determined from one spectrum. We present the Brillouin spectra to confirm this fact for a single crystal (alpha) -LiIO₃. The birefringence of (alpha) -LiIO₃ is n_o - n_e equals 0.149 at 514.5 nm.
