<111> Orientation Gallium Gadolinium Garnet Single Crystal Substrates
GGG single crystal substrates of different tangential,which can achieve the best lattice match with this magento-optical material,thus ensuring the YIG,BIG film epitaxial growth be successful.It has good physical and mechanical properties and chemical stability.
GGG is also substrate material for microwave devices.
In the optical communication devices,require a lot of using 1.3u and 1.5u optical isolator,which core component is the YIG or BIG film been placed in a magnetic field.
Crystro's GGG wafer is grown by Czochralski method.Max diameter reach 4inch,it's now the biggest size in this filed,we can custom size and specs ,rougness<0.5nm.Magneto-optical single crystals like GGG,SGGG,TGG,TSAG are our main products.
