✦ Synopsis

LiNbO 3 crystals has been grown. The crystal composition and phase are analyzed by X-ray diffration. The optical damage resistance ability of Zr: LiNbO 3 crystals is studied by the SΓ©narmont compensation method and the transmitted beam pattern distortion method. The saturated value of the birefringence change of 6 mol % Zr: LiNbO 3 crystal is 1.01Γ—10 -4 , which is seven times smaller than that of congruent pure LiNbO 3 crystal. The results of UV-Visible and IR absorption spectra of Zr: LiNbO 3 crystals powerfully confirm that the optical damage resistance threshold concentration of the Zr 4+ ions doped in LiNbO 3 crystals is about 6 mol % in the melt.
