High Thermal Conductivity TGG Bar Magneto Optical Crystals

Magneto Optical Crystal TGG Single Crystal High thermal conductivity

Description:

Terbium gallium garnet (Tb3Ga5O12, TGG) is a crucial category of magneto-optical materials for use in the visible and the near-infrared spectral regions((400-470nm and 500-1500nm)). The TGG crystal possesses a large Verdet constant (35 RadT−1m−1 at 1064 nm), high thermal conductivity (7.4 Wm−1K−1), low optical losses (< 0.1%/cm) and high laser damage threshold (> 1 GW/cm2). Therefore, it is an attractive Faraday-rotating crystal suitable for constructing magneto-optical isolators, magneto-optical switches, magneto-optical modulators and so on,widely used in YAG, Ti-doped sapphire and other multi-stage amplification, ring type, seed injection laser

Features:

• Large Verdet Constant (Typical 35 dB,Up to 40dB)
• Low optical losses (<0.1%/cm)
• High thermal conductivity (7.4W m-1K-1).
• 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

Applications:

• Faraday Rotator;

• Optical Isolator.

• Magnetic sensor
