OEM Factory for Er Yb Cr Glass - TSAG crystal – Dien

TSAG Faraday crystal is an ideal magneto-optical crystal, which is mainly used in the wavelength range of 400-1600 nanometers, namely the visible and infrared bands. TSAG is an indispensable crystal for the next generation of high-power lasers due to its advantages of high constant, good thermal and mechanical properties. Compared with TGG, the Verdet constant at 1064 nm of TSAG is 20 % higher and the absorption is 30 % lower. Recently, the optical and scintillation properties of TSAG (Tb₃Sc₂Al₃O₁₂) crystal was investigated, and capabilities to be used as a scintillator screen was demonstrated.
Main Features of TSAG:
•   Large Verdet constant（48radT-1m-1 at 1064nm），about 20% higher than that of TGG;
•   Low absorption（＜3000ppm/cm at 1064nm），about 30% less than that of TGG;
•   High power compliant;
•   Low thermally-induced birefringence;
•   Making the isolator small.
Main Applications:
• Faraday Rotator;
• Optical Isolator.
