TB3Ga5O12 Magneto Optical Material TGG Single Crystal For Optical Isolator
TB3Ga5O12 Magneto Optical Material TGG Single Crystal Optical Isolator In Fiber Laser
Magneto Optical Material TGG Single Crystal Optical Isolator In Fiber Laser
Description:
The magneto-optical crystal TGG crystal is key material for free space faraday isolator. It's 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.
