Abstract
A series of Zn, Fe double-doped LiNbO3 crystals were grown by Czochralski technique with 0.015wt% of Fe2O3 and with different concentration of ZnO. The defect structures of the Zn:Fe:LiNbO3 crystals were studied by X-ray diffraction analyses and IR absorption spectra. The results indicated that the lattice constants of the Zn:Fe:LiNbO3 increase with the concentration of ZnO increasing in the crystals. The result indicates that the absorption peaks of the IR transmission spectra shift to the shorter wavelength with the increasing of concentration of ZnO. The optical damage resistance ability of the Zn:Fe:LiNbO3 crystals were investigated by straightly observing transmission facula distortion method, respectively. The results demonstrate that, compared with of Fe:LiNbO3, the optical damage resistance ability of the Zn (7.0mol%):Fe:LiNbO3 crystals is two orders magnitude higher than that of LiNbO3 crystal. 6.0mol% of ZnO is the perfect doping concentration.
