Lithium niobate wafer
from G&H

Already since 1967 former Crystal Technology in California and now G&H is manufacturing and develop further lithium niobate wafer. Even today wafer with a diameter of up to 125 mm will be produced, which is the basis for most optical applications.

Lithium niobate (LiNbO3 or LN) is one of the most versaitile and most developed active optical material. This crystal finds it’s need in electro-optics, acousto-optics, non-linear optics and guided wave-optics. To the fundamental attractive characteristics of lithium niobate are: high area of transparency, high electro-optical and non-linear optical coefficient, very high electro-mechanical coupling coefficient as well as high chemical and mechanical stability.

Besides pure LN-wafer we can also provide up to 5% MgO doped LN-wafer.
