TSAG Crystals
Higher Performance: TSAG crystals exhibit stronger functionalities compared to TGG crystals.
Verdet Constants: High Verdet constants indicate the material’s strong ability to induce Faraday rotation.
Thermal Stability: Low thermal-induced birefringence ensures stable performance under varying thermal conditions.
Mechanical Strength: TSAG crystals have excellent mechanical characteristics, making them suitable for high-power lasers.
Wide Transmission Range: TSAG crystals have a broad transmission range from 400nm to 1600nm, covering both visible (VIS) and near-infrared (NIR) zones.
Compact Designs: The material properties allow for the design of compact and efficient optical devices.
Applications: Faraday Optical Isolators, Faraday Rotators and Circulators, Scintillators, etc.
TSAG crystal is an advanced magneto-optical material used in the manufacturing of Faraday optical isolators for next-generation fiber lasers. Faraday isolators are essential optical elements that mitigate undesirable feedback in lasers with continuous waves and repetitive pulses, which can cause detrimental thermal effects.
