摘要：

A model is proposed for photo- and thermally induced processes in lithium niobate crystals. The model is based on the presence of structural defects formed as a result of departure of the crystal composition from stoichiometry. Defects of the type Nb-Li-Nb-Li are introduced and the influence of oxidation-reduction heat treatment on the optical characteristics of the crystals is analyzed.
