Paper Abstract

New results on " as-grown" and protonated lithium tantalate crystals are given. Special attention is paid to crystals having different stoichiometry. The proton exchange in X- and Z-cut substrates was processed in pure benzoic acid for different time intervals. Optical waveguide measurements and infrared absorption studies have been performed to study the incorporation of protons. Definite correlation between the lithium concentration of the original crystals and the refractive index change in the exchanged layers has been observed.
