TSAG Magneto Optical Crystal Can Replace TGG Single Crystals
Description:
TSAG is perfect magneto optical crystal which can be used in visible and infrared wavelength regions. Good thermal and mechanical properties make TSAG very reliable material suitable for next generation fiber lasers. Compared to TGG, TSAG has about 20% higher Verdet constant and about 30% lower absorption at 1064 nm.
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
Imaging applications:Scintillation properties of TSAG crystal for imaging applications
