Product Description
High Performance TGG Crystal Faraday Isolator
Key Performance Features
- Large Verdet Constant: 35-40 dB isolation performance
- Low optical losses: <0.1%/cm transmission efficiency
- High laser damage threshold: >1 GW/cm² power handling
- Twice the Verdet constant compared to terbium-doped glass
- Thermal conductivity 7.4 W/m·K - 10x greater than typical glass
- Superior optical performance vs Tb-doped glasses
Product Overview
Terbium Gallium Garnet (TGG) crystals represent the optimal magneto-optical material for Faraday polarizers and isolators. These single crystals deliver exceptional performance across the 400-1100nm wavelength range (excluding 470-500nm), combining high magneto-optic constant with superior thermal management capabilities.
