Product Details
Size 10x10x5mm TB3Ga5O12 TGG heFaraday Optical Crystal
Applications:
Faraday Rotator
Faraday polarizer
Magnetic sensor
Faraday Isolator
Fiber Isolator
Description:
Faraday polarizer is composed of the TGG crystal rod and a
specially designed magnet. The polarization of the beam through the
magneto-optical materials deflexed and direction of the deflection
only has some relations with the direction of the magnetic field
and has nothing to do with the direction of the beam propagation.
An optical isolator is an optical component which allows the
transmission of polarized light in only one direction.
Features:
- Large Verdet Constant (Typical 35 dB,Up to 40dB)
- Low optical losses (<0.1%/cm)
- High laser damage threshold (>1GW/cm2).
- TGG has twice the Verdet constant of a terbium-doped glass.
- Thermal conductivity is an order of magnitude greater than typical
glass.
- Optical losses are lower for TGG than Tb-doped glasses
