4inch Diameter 500µM Ggg Gadolinium Gallium Garnet Substrates

4inch Diameter 500µm Thick GSGG Substrates


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. The good physical, mechanical and chemical stability of GGG also ensures the requirements of the substrate in the process of film perparation. The substrate material is made of microwave isolator GGG.

Anhui Crystro Crystal Materials Co., Ltd. is specialized in research and development of crystal science and technology, our
