Relations Between some Acoustic and Optical Quantities and their Dependence on the Stoichiometry of the Lithium Niobate Crystal
摘要
Abstract
New relationships that express the relationships between some optical and acoustic quantities and the stoichiometry of the lithium niobate single crystal suitable for rapid estimation have been obtained. It is shown that by determining the damping coefficients of transverse and longitudinal hypersonic waves, it is possible to estimate the refractive indices in the terahertz range with great accuracy and determine the stoichiometric composition of the lithium niobate crystal.
