Abstract

OH-absorption properties of the optical damage region in a series of codoped In/Mg:LiNbO₃ crystals with various Li/Nb ratios have been investigated. The OH^--associated vibrational peak at 3507 cm^-1 is confirmed to occur in crystals with Li/Nb ratio of 0.94. For codoped In/Mg:LiNbO₃ crystals with Li/Nb ratio of 1.05 and 1.20, the OH^--associated vibrational peaks are detected at 3536 and 3507 cm^-1 as well. A new peak at 3518 cm^-1 attributed to a (In_Nb)^2--OH^--(Mg_Nb)^3- defect center is revealed in crystals with Li/Nb ratio 1.38. When the "In-Mg threshold" concentration is reached, the optical damage resistance ability of codoped In/Mg:LiNbO₃ crystals is greatly improved.
