Brief: Discover the Terbium Gallium Garnet (TGG) Crystal, the ideal magneto-optical crystal for Faraday isolators and rotators. With excellent properties like a large Verdet constant and high thermal conductivity, TGG crystals are perfect for applications in the 400 nm-1100 nm wavelength range.
Related Product Features:
  • Large Verdet Constant (35 Rad T-1m-1) for superior magneto-optical performance.
  • Low optical losses (<0.1%/cm) ensuring minimal light attenuation.
  • High thermal conductivity (7.4W m-1K-1) for efficient heat dissipation.
  • High laser damage threshold (>1GW/cm2) for durability under intense laser use.
  • Optimal for Faraday Rotators and Optical Isolators in the 400 nm-1100 nm range.
  • Excellent surface quality (10/5 Scratch/Dig) for precision applications.
  • High Mohs hardness (8) for resistance to physical wear and tear.
  • Precise specifications including wave front distortion < λ/8 wave and parallelism < 30 arc seconds.
Faqs:
  • What is the wavelength range for which TGG crystals are optimal?
    TGG crystals are optimal for the wavelength range of 400 nm to 1100 nm, excluding 470-500 nm.
  • What are the key applications of TGG crystals?
    TGG crystals are primarily used in Faraday Rotators and Optical Isolators due to their excellent magneto-optical properties.
  • What makes TGG crystals suitable for high-power laser applications?
    TGG crystals have a high laser damage threshold (>1GW/cm2) and high thermal conductivity (7.4W m-1K-1), making them durable and efficient under intense laser use.
