Paper Abstract

We investigate the characteristics of ultraviolet (UV)-induced defect centers that leads to a transient broad absorption band extending from the near-UV to the near-infrared spectral regions in LiNbO3:Mg. The thermal activation energy of the UV induced defect centers was measured to be 0.65 eV and holes were found to be the UV-induced charge carriers. These results indicate that intermediate states O- act as the UV-induced defect centers in LiNbO3:Mg. In addition, we demonstrate nondestructive two-color holography by use of the UV-induced near-infrared photorefractivity in LiNbO3:Mg.
