Lithium Niobate Wafers


Product Description

Hobbite® Wafer (Lithium Niobate Wafers)

Hobbite can provide Lithium Niobate (LiNbO3) applications include electro-optic modulator and Q-switch for Nd:YAG, Nd:YLF and Ti:Sapphire lasers as well as modulator for fiber optics.

We also supply “black” wafers free of pyroelectric discharge: detailed specifications

Examples of common applications of Lithium niobate (LiNbO3) are illustrated in this diagram:
