Product Description
Product Overview
TSAG optical crystals are advanced magneto-optical materials specifically engineered for high-power laser applications in the 400-1600nm wavelength range. With superior performance characteristics compared to traditional TGG crystals, TSAG crystals deliver enhanced efficiency and reliability for demanding optical systems.
Key Advantages
- Large Verdet constant (48 radT⁻¹m⁻¹ at 1064nm) - 20% higher than TGG crystals
- Low absorption (<3000 ppm/cm at 1064nm) - 30% lower than TGG crystals
- High power compliance for demanding laser applications
- Low thermally-induced birefringence for stable performance
- Compact isolator design capabilities
Applications
- Faraday isolators for high-power laser systems
- Scintillation imaging applications and detector screens
Performance Comparison
TSAG crystals demonstrate significant performance improvements over traditional TGG crystals, featuring a 20% higher Verdet constant and 30% lower absorption at 1064nm, making them ideal for next-generation high-power laser systems.
