Optical quality near stoichiometric lithium niobate doped with Fe2O3 and MnO was grown by top-seed solution method.The results of UV absorption indicate that the ratio of n(Li)/n(Nb) is close to stoichiometric.The exponential gain coefficient,diffraction efficiency and response time were measured by tow wave coupling light.The results show that the exponential gain coefficient and diffraction efficiency of near stoichiometric crystal reach to 25 cm－1 and 68.3%,respectively,while response time is less than 1 second.Holographic storage experiment was carried out using the grown crystal.The results indicate that the quality of image storage is much batter than that of congruent crystal with the same dopants,and the recording speed is three times faster than that of congruent crystal.
