Near-Stoichiometric Lithium Niobate
Compared with the crystal of the same composition, the electro-optic coefficient, nonlinear optical coefficient, periodic polarization reversal voltage and applied photorefractive properties of stoichiometric LiNbO3 crystal are greatly improved. With such excellent physical properties and wide application prospects, near stoichiometric lithium niobate crystal has rapidly become a competitive optoelectronic material.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
