Lithium niobate (LiNbO3, LN) is a multi-purpose material in photonics and optoelectronics fields. It features excellent nonlinear, electro-optic, and piezoelectric properties. it is widely used as electro-optic modulators and Q-switches for Nd:YAG, Nd:YLF and Ti:Sapphire lasers as well as modulators for fiber optics.
