  • Abstract
    In this paper we describe a new nonlinear phenomenon observed during scattering of a single Ar laser beam in a photorefractive KNbO 3:Fe crystal. A vertically polarized laser beam initially scatters in a cone angle behind the crystal, and later rearranges in a hexagonal spot array. These six spots may rotate about the center, and the rotation speed and the intensity ratio of the peripheral spots to the central spot are dependent on the intensity and diameter of the incident beam
