采用直拉法(Cz)生长了高透明的(Tb(1-x)Prx)(3)Ga5O12(TPGG)单晶。通过X射线衍射分析对生长的晶体进行表征，结果表明该晶体属于立方结构，结晶度较高。详细分析了TPGG的光学和磁光特性，并确定了其在室温下作为法拉第旋转器的品质因数。 TPGG在632.8 nm处的费尔德常数为-182.43 rad m(-1) T-1，比铽镓石榴石(TGG)大36.14%。还测量了 TPGG 的热导率和激光诱导损伤阈值 (LIDT)。总体而言，到目前为止，本文研究的 TPGG 单晶表现出比商业 TGG 更优越的性能，因此它有潜力满足 VI-IR 区域对新型和改进的法拉第旋转器不断增长的需求。 (C) 2015 年由 Elsevier B.V. 出版
A highly transparent (Tb(1-x)Prx)(3)Ga5O12 (TPGG) single crystal was grown by the Czochralski (Cz) method. The grown crystal was characterized by x-ray diffraction analysis which showed the crystal belongs to cubic structure with high crystallinity. The optical and magneto-optical properties of TPGG are analyzed in detailed and its figure of merit as Faraday rotator has been determined at room temperature. The Verdet constant of TPGG at 632.8 nm was -182.43 rad m(-1) T-1, which is 36.14% larger than that of terbium gallium garnet (TGG). The thermal conductivity and laser induced damage threshold (LIDT) of the TPGG were also measured. Overall, the TPGG single crystal studied here exhibits superior properties than the commercial TGG so far, therefore it has potential to cover the increasing demand for new and improved Faraday rotators in the VI-IR region.
