The Li-rich Zn-doped LiNbO3 (LN) crystals were grown by the Czochralski method. The structure of the crystals was measured by ultraviolet-visible absorption spectra. The results indicated that the Li-rich Zn-doped LN crystals had the same characteristics as the pure LN crystal. After Zn2+ entered into the lattice of Li-rich Zn-doped LN crystal, it replaced NbLi firstly. When there was no NbLi, Zn2+ replaced Li+ then. The second harmonic generation (SHG) property of Li-rich Zn-doped LiNbO3 crystal was measured. The results showed that the SHG conversation efficiency of Li-rich Zn-doped LiNbO3 crystals was higher than that of Zn-doped LiNbO3 crystals.
