Highly Transparent Terbium Gallium Garnet TGG For Visible–Infrared Optical Isolator

Description:

Highly transparent terbium gallium garnet (Tb3Ga5O12; TGG) single crystal having a large Verdet constant based on the visible and near-infrared region (VIS–NIR) Faraday rotator was grown by Floating Zone (FZ) growth machine. We successfully grew TGG single-crystal rods of 8–10 mm in diameter, which was suitable for the use in optical devices. The Faraday rotation (B = 0.55T) was investigated at wavelength of 532, 632.8, 1064 nm at room temperature. The lower weak absorption coefficient, higher Verdet constant, thermal conductivity and laser induced damage threshold (LIDT) compared to the commercial TGG gives the great potential of using this new method to meet the increasing demand of VIS–NIR Faraday rotators (FRs).

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.
