Laser Crystal Magneto-Optical Crystal​ TGG

Magneto-Optical Crystal

Terbium Gallium Garnet (TGG) crystal is an excellent magneto-optical crystal used in the range of 400nm-1100nm, excluding 475-500nm. It has a large magneto-optical constant, low light loss, high thermal conductivity and high laser damage threshold. It is widely used in multi-stage amplification, ring type and seed injection lasers such as YAG and Ti-doped sapphire.
