product details

Lithium Niobate LiNbO3 crystal substrate


LiNbO3 is a nonlinear optical grade crystal, it widely used in parametric oscillators, frequency doubling, acousto-optic devices, optical modulators. MgO-doped LiNbO3 can effectively increase the damage threshold of the LiNbO3 crystal.
Lithium Niobate(LiNbO3) crystals are widely used in optical communication, information processing, integrated optics, image storage, harmonic generation, frequency doubling devices, parametric oscillations, frequency multiplication of 1064nm lasers and quadruple frequency phase matching device etc.
