Laser Materials
Terbium Gallium Garnet (TGG) is an excellent magneto-optical crystal used for optical isolator and rotator devices in the range of 400nm-1100nm, excluding 470-500nm. TGG has a high Verdet constant resulting in the Faraday effect making it most suitable for Faraday devices.
Advantages include:
• High Verdet Constant (35 Rad T⁻¹ m⁻¹)
• Thermal Conductivity (7.4W m⁻¹ K⁻¹)
• Low optical losses (<0.1%/cm)
