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.
