Product Description
Customized TGG Magneto Optic Crystal Rods
Terbium gallium garnet (Tb3Ga5O12, TGG) is a critical magneto-optical material optimized for visible and near-infrared spectral regions (400-470nm and 500-1500nm). These crystal rods feature exceptional optical properties including high Verdet constant, superior thermal conductivity, and excellent laser damage resistance.
Key Performance Advantages
- Large Verdet Constant (35-40 RadT⁻¹m⁻¹ at 1064 nm)
- Low optical losses (<0.1%/cm)
- High laser damage threshold (>1 GW/cm²)
- Twice the Verdet constant of terbium-doped glass
- Thermal conductivity 7.4 Wm⁻¹K⁻¹ (10x greater than typical glass)
- Lower optical losses compared to Tb-doped glasses
Primary Applications
- Faraday Rotators for optical isolators
- Magnetic sensors and measurement systems
- Magneto-optical switches and modulators
- YAG, Ti-doped sapphire, and multi-stage amplification lasers
- Ring type and seed injection laser systems
