Abstract
Doping different concentration of ZrO2in Mn:Fe:LiNbO3crystals, a series of Zr:Mn:Fe:LiNbO3crystals were grown by the Czochralski method. The infrared transmission spectra and the photo-damage resistant ability of the crystals were measured. The OH-absorption peak of Zr (2mol%):Mn:Fe:LiNbO3crystal shifts to ultraviolet. The photo-damage resistant ability of Zr (3mol%):Mn:Fe:LiNbO3crystal is about three orders of magnitude higher than that of Mn:Fe:LiNbO3crystals. The diffraction efficiency, response time of Zr:Mn:Fe:LiNbO3crystals were measured by two-wave coupling experiment. The response time of Zr (3mol%):Mn:Fe:LiNbO3crystal is only one tenth of that of Mn:Fe:LiNbO3. The mechanism of OH-absorption peak shifting and improvement of holographic storage properties was discussed.
