LiNbO3 crystals doped with the same concentration of ZnO and with the different concentration of Fe2O3 have been grown by a top-seeded-solution-growth (TSSG) method. The IR transmittance spectra, UV-Vis absorption spectra, lattice constants, and Curie temperature were measured. In two-wave coupling experiments, writing and erasure curves were measured, and writing time constants,erasure time constants, and maximum diffraction efficiency of the crystals were obtained from the curves. The influences of Fe2O3 doping concentration on photorefractive properties were studied.
