Green-induced infrared absorption (GRIIRA) properties were characterized for LiNbO3 (LN) and LiTaO3 (LT) single crystals. GRIIRA was measured using a photothermal common-path interferometer. Several LN and LT with different concentrations and doping materials were investigated. Mg-doped near-stoichiometric LT (Mg-SLT) had the lowest IR absorption. In addition, no GRIIRA was observed only in MgSLT. Therefore, Mg-SLT could be the most suitable material for high power green generation. In LN crystals, higher GRIIRA was observed in non-doped congruent LN (CLN) which has low photorefractive damage threshold. The 1.3 mol% Mg doped SLN had the lowest GRIIRA within the investigated LN crystals. Even in the materials with low GRIIRA, two different characteristics were observed; initially high IR absorption and slow relaxation time of GRIIRA. The first characteristic was observed for Mg doped LN which has a higher number of scattering centers. The second was strongly observed in Mg doped LN which has a higher level of absorption in the UV region.
