Abstract

In:Tm:LiNbO₃ crystals were grown by the Czochralski technique with fixed concentrations of Tm₂O₃ and differing concentrations of In₂O₃. Their ultraviolet-visible absorption spectra were measured in order to investigate their defect structures and their optical damage resistance was characterized by the transmission light spot distortion method. The results show that the optical damage resistance of the In:Tm:LiNbO₃ crystals improves with the doping concentration of In₂O₃ increasing. The dependence of the optical damage resistance on the defect structure of In:Tm:LiNbO₃ crystals is discussed in detail.
