In this paper, the redox treatment and incoherent homogeneous illumination were tried for the suppression of the photoinduced light scattering in LiNbO:Fe. Meanwhile, the effects of both the redox treatment and incoherent homogeneous illumination on the holographic storage properties of LiNbO:Fe were also studied. Our experimental data show that the reduction treatment sacrifices the diffraction efficiency for the suppression of photoinduced light scattering in LiNbO:Fe. By contrast, incoherent homogeneous illumination with the wavelength of 460 nm is efficient to suppress the photoinduced light scattering without any tradeoff on the holographic storage performance of LiNbO:Fe. The superiority of homogeneous illumination over the reduction treatment was attributed to the untouched acceptor concentration under the homogeneous illumination. [ABSTRACT FROM AUTHOR]
