Abstract In this paper, we systematically studied the scattered light when the stripe beam of ordinary polarized light and extraordinary polarized light are incident to the LiNbO3:Fe crystal, respectively. First, we observed the variation of scattered light with the different angle between the stripe beam and the c-axis. And find the scattered light is growing with time along the c-axis direction of the crystal when the e-light is incident; while the scattered light is growing along a special direction which is not the c-axis direction or the stripe direction, when o-light is incident to the crystal. Then we analyzed the causes of these phenomena. In addition, we also studied the diffraction efficiency of o-light and e-light, and the raster image in the crystal.
