TGG Faraday Crystals

TGG Faraday crystal is used in the range of 400-1100 nm wavelength (excluding 470-500 nm).TGG has a high Verdet constant and is resistant to laser damage. It is a magnetized crystal, so a Faraday effect occurs when the beam passes. TGG is the perfect magnetized crystal material for Faraday rotator and Faraday isolator. Therefore, it is widely used in measuring devices,lasers and optical fiber system.
