Abstract 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.

Tb 3 Ga 5 O 12 磁光晶体的生长及性能研究

摘要 Tb3Ga5O12 (TGG) 晶体在高纯度80%N2 + 20% CO2 气氛下，在射频(RF) 诱导加热的铱坩埚中通过直拉法成功生长。与 TGG 的标准卡片相比，在 XRD 图中没有发现杂质峰。在室温下在可见-近红外区域 (VIS-NIR) 中研究了透射光谱，这表明 TGG 晶体在 500-1100 nm 处具有高透射率。详细讨论了生长晶体的 (1 1 1)、(1 0 0)、(1 1 0) 的法拉第旋转、维尔德常数和磁化率，证实了 TGG 晶体的法拉第效应是各向异性的具有磁化率，并且[1 1 1]的法拉第效应已被证明是最好的，并且还在室温下在不同波长下研究了[1 1 1]的Verdet常数。还详细分析了晶体的热导率和激光诱导损伤阈值。
