摘要
Tb3Ga5O12 (TGG) crystal was grown successfully by the Czochralski method in an iridium crucible with radio frequency (RF)-induced heating under high purity 80%N2 + 20% CO2 atmosphere. None impurity peaks could be found in the XRD patterns compared to standard cards of TGG. Transmittance spectrum was investigated in the visible-near infrared region (VIS-NIR) at room temperature, which indicated the TGG crystal had high transmittance at 500–1100 nm. The Faraday rotations, Verdet constants and magnetic susceptibility of (1 1 1), (1 0 0), (1 1 0) of as-grown crystal have been discussed in detail confirming that Faraday effects of the TGG crystals are anisotropic which is related with magnetic susceptibility, and the Faraday effects of [1 1 1] have been proved to be the best, and the Verdet constants of [1 1 1] was also investigated at different wavelength at room temperature. The thermal conductivity and laser induced damage threshold of the crystal were also analyzed in detailed.
