In∶Nd∶LiNbO_3 crystals were grown by Czochralski method with In_2O_3 and Nd_2O_3 as dopants.The optical damage resistance ability of In∶Nd∶LiNbO_3 crystal was investigated by light spot distortion method and the photorefractive threshold of In∶Nd∶LiNbO_3 measured is 1.98×10 4 W/cm 2,two order of magnitude higher than that of Nd∶LiNbO_3 crystal,1.6×10 2 W/cm 2.The structure of the crystals was measured by ultraviolet-visible absorption spectra.The results show that the absorption edge shifted to the ultraviolet band.The double-frequency property of In∶Nd∶LiNbO_3 crystal was measured.The results indicate that the SHG conversation efficiency of In∶Nd∶LiNbO_3 crystals was twice higher than that of Nd-doped LiNbO_3 crystals and the phase matching temperature was near room temperature.
