We report our observation of the generation of a conical ring when two extraordinarily polarized beams are incident upon a heavy-doped LiNbO3. We demonstrate that large refractive index change, multiple scatterings and diffractions through Bragg- mismatching condition exist in the crystal. It leads to the generation of the conical ring.
