Magneto-optical Crystal Gadolinium Gallium Garnet ( GGG )

Gadolinium Gallium Garnet (GGG, Gd3Ga5O12) is a synthetic crystalline material of the garnet group, with good mechanical, thermal, and optical properties. It is typically colorless. It has cubic lattice, density 7.08 g/cm3 and Mohs hardness is variously noted as 6.5 and 7.5. Its crystals are made by Czochralski method and can be made with addition of various dopants for modification of color. It is used in fabrication of various optical components and as substrate material for magneto–optical films. It also finds use in jewelry as a diamond simulant.


Main Advantages:

  • Large dimensions,from 2.8 to 76mm.
  • Low optical losses (<0.1%/cm)
  • High thermal conductivity (7.4W m-1K-1).
  • High laser damage threshold (>1GW/cm2)
