TGG
Description:
The magneto-optical crystal TGG crystal is an optimum material for Faraday devices (Rotator and Isolator) in the wavelength range 400 nm-1100 nm, excluding 470-500 nm. TGG crystal has a combination of excellent properties such as large Verdet constant, low light loss, high thermal conductance and high light damage threshold which makes it a unique material for Faraday devices.
Features:
l Large Verdet Constant (35 Rad T-1m-1);
l Low optical losses (<0.1%/cm);
l High thermal conductivity (7.4W m-1K-1);
l High laser damage threshold (>1GW/cm2).
Applications:
l Faraday Rotator;
l Optical Isolator.
