Gadolinium gallium garnet (GGG)

In optical communication equipment, 1.3 μ And 1.5 μ The core part of the optical isolator is YIG or big film placed in magnetic field. The GGG single crystal substrates with different tangential directions can match the crystal lattice of this kind of magneto-optical materials, so as to ensure the successful epitaxial growth of YIG and big films.

In the field of magnetic refrigeration, GGG Crystal has been successfully used in the temperature range below 20K for market he Ⅱ flow and pre stage refrigeration of helium nitrogen liquefaction.

Main advantages:

Low optical loss (< 0.1% / cm)

High thermal conductivity (7.4w M-1 k-1)

High laser damage threshold( ± 1GW/cm ²)

Application:

Magneto optic film substrate

High temperature superconducting substrate
