| Abstract: | The authors have observed high order diffraction effect using the two-wave coupling in photorefractive crystal LiNbO3. The experimental results are analysed with the coherent theory of light diffracted by index phase grating and the formula of angular distribution of diffracted wave is obtained. The experimental .results are in consistent with theoretical forpsula. |
