Abstract

Er:LiNbO₃ and Mg:Er:LiNbO₃ crystals were grown by the Czochralski method. All of crystals were possessed with polarization. In order to investigate the mechanism of OH absorption peak shift, the infrared absorption spectra of the crystals were measured. The absorption edge of ultraviolet-visible absorption spectrum of Mg:Er:LiNbO₃ crystal showed a shift towards shorter wavelength. The fluorescence spectra of the crystals were investigated. The laser vibrate of Mg:Er:LiNbO₃ crystal was realized easily at 1.54 micrometers , 0.887 micrometers and 0.5 micrometers . Benzoic acid was used as proton transfer reagent to make the waveguide substrate. By using the holograph method, the photodamage resistance ability and the enhance mechanism of the Mg:Er:LiNbO₃ crystal waveguide substrate was measured.
