(TSAG) crystal is attracting much attention for visible and near-infrared isolator applications due to its high transmittance, large laser damage threshold, low absorption coefficient and excellent magneto-optical properties. However, it is difficult to grow large-size crack-free single crystals. In this work,high quality TSAG crystal was successfully grown by the Czochralski method. The transmittance in the wavelength of 400-1 500 nm is as high as 84%. The thermal conductivity is higher than that of commercial Tb

(TGG) crystal. More importantly, the Verdent constant of TSAG is 1.2 times that of TGG crystal. Therefore, TSAG crystal is promising magneto-optical crystal for high power isolator applications.
