Abstract
Abstract In:Mn:Fe:LiNbO 3 crystal was grown by the Czochralski method and oxidized for the first time. The OH − absorption band of In(3 mol%):Mn:Fe:LiNbO 3 crystal was found to be at 3507 cm −1 . The nonvolatile holographic recording in In(3 mol%):Mn:Fe:LiNbO 3 crystal was realized by the two-photon fixed method. The recording time of In:Mn:Fe:LiNbO 3 crystal is only a half of that of Mn:Fe:LiNbO 3 crystal, and the ratio of signal to noise is improved, too. At last, the mechanism of OH − absorption band shifting and two-photon fixed was discussed.
