Abstract

A detailed optical absorption study has been performed on a series of chemically reducedlithium niobate crystals. A threshold absorption above 3.8 eV has been identified as a bandgap excitation, while the entire subbandgap absorption has been demonstrated to be due to a single defect via optical bleaching experiments. A model based on a bipolaron is proposed to explain the observed optical properties.
