Gallium Gadolinium Garnet (Gd3Ga5O12 or GGG) Single Crystal

Gallium Gadolinium Garnet (Gd3Ga5O12 or GGG) single crystal is material with good optical, mechanical and thermal properties which make it promising for use in fabrication of various optical components as well as substrate material for magneto – optical films and high – temperature superconductors.

Standard products: wafers and substrates with sizes from 10 x 10 mm to dia. 76.2 mm, thickness 0.5 mm and 1.0 mm, one side or both sides polished 20/10 S/D, [111] or [100] cut. Other products are available on request.


Main Advantages:

  • Large dimensions,from 2.8 to 76mm.
  • Low optical losses (<0.1%/cm)
