Abstract

We propose and demonstrate simple methods to determine accurately the dispersion of electro-optic coefficients and effective charge carrier densities of photorefractive crystals. A Ce-doped BaTiO₃:Ce crystal was determined. Then by measuring the two-beam coupling coefficient at different wavelengths and crossing angles, we can determine accurately the variation with wavelength of effective charge carrier density of the crystal.
