 Lithium Niobate ( LiNbO3) is notable by a favourable balance of electro-optic, acoustic, piezoelectric, pyroelectric and non-linear optical attributes and is therefore the best material for applications in electro-optical, non-linear optical, and acoustic devices, high-temperature acoustic transducers, receivers-transmitters of acoustic vibrations, air force acceleration meters, acoustic wave delay lines, deflectors, generators of non-linear distorted waves, acoustic filters, electro-optical modulators (Q-switches), converters, frequency doublers and resonators in laser systems, non-linear elements in parametric light generators, and many others. The listed devices can be found anywhere from consumer electronics (TV sets and cell phones) and medical instruments (surgical and therapeutical appliances) to advanced laboratory and scientific equipment (biotechnology, frequency standards, metal cutting, shaping, scribing). |
