LiNbO3 crystal has excellent electro-optic, acousto-optic, piezoelectric and nolinear properties, it is widely used in the field of civil and military purposes, with the development of photoelectric technology, LiNbO3 crystal is increasingly emphasized in the application of defence technology, it is a kind of important multifunctional crystal with good nonlinear properties, its nonlinear optical coefficient is relatively large, which can realize the critical phase matching. As the electro-optic crystal, it has been important optical waveguide materials, as the piezo-electric crystal, it can used to make middle and low frequency SAW filter, high power high temperature ultrasonic transducer etc., dope LiNbO3 materials is also has widely applications, Mg:LN crystal can greatly improve the anti-laser damage threshold, Nd:Mg:LN crystal, can realize the frequency doubling effect, Fe:LN crystal can used in the optical holographic storage.


LiNbO3crystal is commonly used material for Pockel Cells, Q-switches and phase modulators, waveguide substrate, and surface acoustic wave (SAW) wafers etc.,
