Popis: | Optical methods of investigation of the defect structures and the composition of lithium niobate (LiNbO3) single crystalsis discussed. The intrinsic defects concentrations in lithium niobate crystals (lithium vacancies (VLi)− and (NbLi)4+ defects, Nb on Li site in the valence state 4+), as a function of the Li/Nb ratio, are also reported. The optical damage resistance of various lithium niobate samples was investigated as a function of the composition. A remarkable increase in the optical damage resistance was found in MgO-doped almost stoichiometric lithium niobate crystals. |
