Lithium niobate crystals have a number of unique properties. Lithium niobate is at the same time a ferroelectric, piezoelectric, pyroelectric, and has high nonlinearly optical and electro-optical coefficients and photorefractive sensitivity. These properties enable these crystals to be used widely in optical and acoustic devices, and photorefractive sensitivity, enhanced by doping with transitional metals, offers new possibilities of using lithium niobate as a recording holographic medium. These properties are determined by the crystal structure of lithium niobate sensitive to physical and chemical effects. Special attention is given in the book to physicochemical features of technology, disruption of stoichiometry in these crystals and detection of this disruption by physical methods. At the same time, the ideas and methods proposed in the book can be used in technology of other crystals.
