TGG - Terbium Gallium Garnet

Terbium Gallium Garnet (Tb3Ga5O12, TGG) is an excellent magneto-optical crystal used in various Faraday devices (Rotators and Isolators) in the range of 400 nm-1100 nm, excluding 475 nm-500 nm.

Advantage:

  • Large Verdet constant (35 Rad T-1 m-1)

  • High thermal conductivity (7.4 W m-1 K-1)

  • High laser damage threshold (> 1 GW/cm2) 

Key Parameters:
