Lithium Niobate Crystals

Download or read book Lithium Niobate Crystals written by I︠U︡riĭ Sergeevich Kuzʹminov and published by Cambridge Int Science Publishing. This book was released on 1999 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 physico-chemical 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.
