Abstract

The pure congruent LiNbO₃, Er:LiNbO₃ and Zn,Er- codoped Li-rich LiNbO₃ crystals were grown by Czochralski method. In order to analyze their structure, the X-ray diffraction method, ultraviolet-visible absorption spectra and infrared absorption spectra of the crystals were investigated. The photo damage resistance ability of the crystals was measured. The Zn,Er-codoped Li-rich lithium niobate crystals showed a decrease in lattice constant values, a shift in absorption edge of ultraviolet-visible absorption spectra towards shorter wavelength, and increase in OH_- absorption peak of infrared absorption spectra towards longer wavelength, and three orders of magnitude increase in phtorefractive damage resistance compared to congruent LiNbO₃ crystal.
