Custom Gd3Ga5O12 Single Crystalline Substrates
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.
GGG has been successfully applied in the magnetic refrigeration
industry in the temperature zone below 20 k for market HeII flow
and helium-nitrogen liquefaction pre-stage refrigeration.
Crystro's GGG has low optical lossed(<0.1%/cm),high thermal
conductivity(7.4W m-1K-1),High laser damage threshold(>1GW/cm2)
