Product Description

Lithium Triborate (LBO) Crystal

TGG is an excellent magneto-optical crystal used in various Faraday devices (Rotator and Isolator) in the range of 400nm-1100nm,excluding 475-500nm.It has 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.
