Product Description

Product Overview

Terbium Gallium Garnet (Tb₃Ga₅O₁₂, TGG) is a premium magneto-optical crystal material designed for high-performance applications in visible and near-infrared spectral regions (400-470nm and 500-1500nm). This single crystal serves as an exceptional alternative to YIG crystals in advanced optical systems.

Key Performance Features

Large Verdet Constant: Typical 35 dB, up to 40 dB
Low Optical Losses: <0.1%/cm absorption rate
High Thermal Conductivity: 7.4 W·m^-1·K^-1
Exceptional Laser Damage Threshold: >1 GW/cm²
Superior Verdet Constant: Twice that of terbium-doped glass
Enhanced Thermal Performance: Order of magnitude greater conductivity than typical glass

Primary Applications

Faraday Rotator systems
Optical Isolator devices
High-precision Magnetic sensors
