Product Description

Lithium niobate LiNbO ₃

LN lithium niobate is an inorganic substance with a chemical formula of LiNbO ₃ . It is a negative crystal and a ferroelectric crystal . The polarized lithium niobate crystal has piezoelectric, ferroelectric, photoelectric, nonlinear optics, thermoelectric, etc. A multi-functional material with photorefractive effect at the same time. Lithium niobate crystal is a good piezoelectric transduction material, ferroelectric material , electro-optic material , as an electro-optic material, it plays an optical modulation role in optical communication, and is widely used in parametric oscillators, frequency doubling, acousto-optic devices, and optical modulation device. The incorporation of MgO can effectively improve the anti-damage threshold of the crystal.
