TGG crystal
Aug 26, 2022
TGG is the best magneto-optic material for making Faraday rotators and isolators, and its applicable wavelength is 400-1100nm (excluding 470nm-500nm).
And its main advantage is:
1:Large magneto-optic constant (35 Rad T-1m-1).2:Low transmission loss (<0.1%/cm).
3:High thermal conductivity (7.4W m-1K-1).4:High resistance to laser damage threshold (>1GW/cm2).
Main application:Faraday rotators, optical isolators, etc.Main Properties:
