TSAG Crystals For Faraday Isolator Large Verdet Constant Than TGG Crystals
Description:
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.
Features:
Large Verdet constant(48 radT-1m-1 at 1064 nm),about 20% higher than that of TGG;
Low absorption(＜3000 ppm/cm at 1064 nm),about 30% less than that of TGG
High power compliant;
Low thermally-induced birefringence;
Making the isolator small.
Applications:
Faraday isolator based on TSAG crystal for high power lasers
