Introduction:

Crystro could offer: GGG wafers and substrates with sizes from 5 x 5 mm to dia. 101.6 mm, thickness 0.5 mm or 1.0 mm, one side or both sides polished. Other products are available on request.

Gadolinium gallium garnet (GGG) is a dedicated substrate for magneto-optical film. Optical communication devices require a lot of using 1.3μ and 1.5μ optical isolator, Its core component is the YIG or BIG film being placed in a magnetic field. Gadolinium Gallium Garnet Crystal Substrates of different tangential, which can achieve the best lattice match with this magneto-optical material, thus ensuring the YIG, BIG film epitaxial growth be successful.

Main Advantages :

• Low optical losses (<0.1%/cm)
• High thermal conductivity (7.4W m-1K-1).
• High laser damage threshold (>1GW/cm2)
