Abstract

In:Mg:Fe:LiNbO₃ crystals were grown by the Czochralski technique with various ratios of Li/Nb=0.85, 0.94, 1.05, 1.20 and 1.38 in the melt. The crystal composition and defect structure were analyzed by the UV-vis and IR spectroscopy. A new narrow OH^--associated vibrational peak at 3518 cm^-1 was revealed in In:Mg:Fe:LiNbO₃ crystals with the ratio of Li/Nb=1.38. It was attributed to a (In_Nb)^2--OH^--(Mg_Nb)^3- defect center. The optical damage resistance of In:Mg:Fe:LiNbO₃ crystals was studied by the transmitted beam pattern distortion method. The results show that when both the In₂O₃ threshold and the "In-Mg threshold" concentrations are reached, as for the Li/Nb ratio of 1.38, the optical damage resistance of In:Mg:Fe:LiNbO₃ crystals is the highest.
