TGG Crystal Rods Magneto-Optic Crystal Material For Optical Isolator Devices

Introduction :

Terbium Gallium Garnet (TGG) is an excellent magneto-optical crystal used in various Faraday devices (Rotator and Isolator) in the range of 400nm-1100nm, excluding 475-500nm.TGG has many advantages compared to other magneto-optical crystals. It has less optical loss, lower thermally induced beam distortion and twice bigger Verdet constant than a terbium doped glass.

Main Advantages :

1. Large Verdet Constant :35 Rad T^-1m^-1

2. Low Optical Losses : <0.1%/cm

3. High thermal conductivity : 7.4W m^-1K^-1

4. High laser damage threshold :>1GW/cm
