Paper Abstract

A change in the Li/(Li+Ta) ratio in LiTaO3 crystals from 0.485 (congruent) to ~0.5 (stoichiometric) results in a up to 130 times reduction in coercive fields for domain reversal and an elimination of the internal fields and domain backswitching. Dramatic differences in the fatigue behavior are also observed, that results in an electro-optic effect that is very sensitive to electrodes in stoichiometric compositions and rather insensitive in congruent compositions.
