Magneto Optical Material Diameter 2.8mm TGG Crystal Rod
Magneto-Optical Material Diameter 2.8*14mm TGG Single Crystal rods
Terbium Gallium Garnet (TGG) is a kind of synthetic garnet, a magneto-optical crystal with a high level of thermal conductivity for Faraday rotators and isolators. It can be used in optical isolators for laser systems, in optical circulators for fiber optic systems, in optical modulators, and in current and magnetic field sensors.
In recent years, the growth of large-size and high-quality TGG crystals has always been a hot research topic in the field of crystal materials. With the unremitting efforts of the professional R&D team, Crystro has successfully grown TGG crystals with a diameter of 100mm in June 2020.
