Abstract

With two extraordinary polarized beams incident on doped KNSBN crystals, higher diffraction orders have been observed when an external electric field is applied. At the same time, high-order anisotropic diffraction cones can also be observed on the viewing screen. These cones are originated from photorefractive four wave mixing which involves incident beams, high-order diffracted beams and forward scattered beams satisfying the phase matching condition. We also investigated the dependence of higher diffraction orders on incident angle.
