详细分析了{Tb 3}[Sc1.95Lu0.05]（Al 3）O 12石榴石（TSLAG）晶体的光学和磁光性质，并与参考化合物Tb 3Ga 5 O 12（TGG）晶体进行了比较。TSLAG呈现出非常高的透射率，特别是在可见光区域中高于TGG的透射率，并且其费尔德常数在任何波长下都大20%。品质因数和消光特性指出了TSLAG相对于TGG的上级特性。在1080 nm处演示了基于TSLAG旋转器的偏振无关光隔离器原型。它的性能证实了这种晶体的高光学质量，表明其成熟的法拉第旋转器应用的发展。
The optical and magneto-optical properties of the {Tb3}[Sc1.95Lu0.05](Al3)O12 garnet (TSLAG) crystal are analyzed in detailed and compared with those of the reference compound Tb3Ga5O12 (TGG). TSLAG presents a very high transmittance, particularly higher than that of TGG in the visible region, and its Verdet constant is 20% larger at any wavelength. The figure of merit and extinction features point out the superior characteristics of TSLAG respect to TGG. A prototype, polarization independent optical isolator based on a TSLAG rotator is demonstrated at 1080 nm. Its performance confirms the high optical quality of this crystal, indicating its mature development for Faraday rotator applications.
