Lithium Niobate (LiNbO3) Crystal

LiNbO3 is the widely used crystal for Surface Acoustic Wave (SAW) wafer, Electro-Optics modulator and Q-switch, Frequency doubler and Optical Parametric Oscilator (OPO), as well as integrated optic waveguide, etc. It has low cost, good mechanical and physical properties as well as high optical homogeneity.
