TGG

TGG

TGG magneto-optical crystals are used in Faraday devices in the field of 400-1100 nm. TGG has many advantages compared to other MO crystals, It has less optical losses, lower thermally induced beam distortion and twice bigger Verdet constant than a terbium doped glass. These features make TGG better appropiate to high average power applications than Tb doped glass.

  • Various sizes crystals are available.
  • We can offer non-Standard TGG crystal sizes upon request.
