Substituted Gadolinium gallium garnet GSGG Single Crystal Wafer
Substituted Gadolinium gallium garnet(GGG) is a special substrate magneto optical flims. In optical commuication equipment, a large number of 1.3 and 1.5 micron optical isolators are needed, and the core component is YIG or BIG film placed in the magnetic field. Different tangential GGG single crystal substrates can be matched with the lattice of such magneto-optical materials, thus ensuring the successful epitaxial growth of YIG and BIG films.
Anhui Crystro has perfect automatic production and inspection equipments, the current products are mainly concentrated in the
Nd:YAG,TGG, TSAG,GGG, LaAlO3,LGS,Ce:GAGG ,Ce:YAG and Ce: LuYAG production,the application of advanced process technology of manufacturing.
We established a crystal research center and keeps developing new crystals. We provide technical support and training for our domestic and overseas customers
