Lithium niobate (LiNbO3) is a compound of niobium, lithium and oxygen, and it is a negative crystal (n0>ne). The deformed lithium niobate crystal is a material with multiple properties such as piezoelectric, ferroelectric, optoelectronic, nonlinear optics, and pyroelectric. Its single crystal is optical waveguide, mobile phone, piezoelectric sensor, optical modulator and various other materials. Important material for linear and nonlinear optical applications. It also has a photorefractive effect. Lithium niobate crystals are widely used in optical communications, information processing, integrated optical circuits, image storage, harmonic generation, frequency doubling devices, parametric oscillation, 1064nm laser frequency doubling, and quadruple frequency phase matching Devices and other aspects. Such as: SAW filter, Q-switch, electro-optical dimmer, parametric oscillator.
