采用提拉法生长了尺寸为Φ22 mm × 28 mm的Tb 3 − xNdxGa 5 O 12单晶。X射线粉末衍射分析和晶格参数计算表明，该单晶属于立方晶系。在450-1500 nm波长范围内的透射光谱表明晶体在900-1450 nm具有低吸收系数。通过消光法计算出的Tb 3-xNdxGa 5 O 12在532、633和1064 nm波长处的维尔德常数分别为225、145和41 radm-1 T-1，均大于已报道的商用TGG（Tb 3Ga 5 O 12）的维尔德常数。在1064 nm处，计算得到晶体的磁光优值为3162°/dB，消光比大于商品TGG。
Tb3−xNdxGa5O12single crystal with dimension of Φ22 mm × 28 mm and a good optical quality was grown by the Czochralski method. X-ray powder diffraction was carried out and lattice parameters were calculated, which showed that the single crystal belongs to cubic crystal system. The transmission spectrum in the wavelength range of 450–1500 nm, which indicated the crystal has low absorption coefficient at 900–1450 nm. The Verdet constants of Tb3−xNdxGa5O12at 532, 633 and 1064 nm wavelengths calculated by the extinction method are 225, 145 and 41 radm−1T−1, respectively, which are larger than that of commercial TGG (Tb3Ga5O12) reported. The magneto-optical figures of merit of the crystal calculated is 3162°/dB at 1064 nm, and the extinction ratio is larger than that of commercial TGG.
