Two leading research physicists from the USSR Academy of Sciences describe the fundamental properties of the lithium niobate crystal, which is indispensable for the development of devices that modulate, shift, and convert laser radiation frequencies, and for the holographic recording of information. They provide insights into the physical processes that take place in the crystal under the influence of such factors as temperature, radiation, electric fields, impurities, and stoichiometric violation, and also offer practical recommendations for its use by researchers and device designers/engineers in optics, electronics, and materials science.

The unique properties of lithium niobate make it an important material for applications in a wide range of fields. It is indispensable for the development of devices for modulation, shift, and conversion of laser radiation frequency, and for holographic recording of information. The Physics and Chemistry of Crystalline Lithium Niobate is devoted to the fundamental properties of the crystal and offers practical recommendations for its use. An insight is given into the physical processes that take place in lithium niobate under the influence of such factors as temperature, radiation, electric fields, impurities and stoichiometric violation. Understanding lithium niobate's peculiarities will enable researchers and device designers/engineers to estimate its opportunities and uses efficiently. In particular, researchers in optics, optoelectronics, electronic engineering, and materials science; and designers of lithium-niobate-based devices will find The Physics and Chemistry of Crystalline Lithium Niobate a comprehensive and up-to-date account of this area of nonlinear optics.
