Abstract
We report large and nonmonotonic dependences of the electro-optic (EO) coefficient r(22) and the corresponding dielectric permittivity in pu re LiNbO3 on the concentration of intrinsic defects related to the dev iation from the stoichiometry of the crystal. This variation is caused mainly by the electro-mechanical contribution. A stoichiometric cryst al possesses both large EO properties and resistance to optical damage which renders it much more suitable for use in laser e-switching than the congruent crystal.
