Lithium niobate (LN) single crystals are a kind of multifunctional crystals, which have excellent piezoelectric effect, electro- effect, acousto-optic effect, nonlinear effect and photorefractive effect. They are widely used in optical communication, information processing, integrated optics, image storage, harmonic generation frequency doubling devices, parametric oscillation, second-harmonic generation of 1064nm lasers, and four-wave mixing phase matching devices, etc. such as SAW filters Q-switches, electro-optic modulators, parametric oscillators, optical waveguide substrates... The incorporation of MgO can effectively improve the damage threshold of the crystal.
Application:
It is widely used in optical communication, information processing, integrated optical circuit, image storage, harmonic generation, frequency doubling device, parametric oscillation, frequency of 1064nm laser, and four-fold frequency matching device and so on. Such as: SAW filter, Q-switch, electro-optic light mod, parametric oscillator, optical waveguide substrate. The doping of MgO can effectively improve the damage threshold of the crystal.
