Faraday effect measurements of holmium oxide (Ho2O3) ceramics-based magneto-optical materials, highly potential material candidates for high-energy laser Faraday isolators, are presented in this paper. Temperature dependence of the Verdet constant of nondoped Ho2O3 ceramics was measured for temperatures 15–305 K at $1.064~\unicode[STIX]{x03BC}\text{m}$ wavelength. The Verdet constant dispersion for wavelengths 0.5–$1~\unicode[STIX]{x03BC}\text{m}$ and $1.064~\unicode[STIX]{x03BC}\text{m}$ was measured for both nondoped Ho2O3 ceramics and Ho2O3 ceramics doped with terbium Tb3+ (0.2 at. %) and cerium Ce3+ (0.1 at. %) ions. The results suggest that the relatively low level of doping of Ho2O3 with these ions has no significant boosting impact on the Faraday effect. Therefore, other compositions of Ho2O3 ceramics-based magneto-optical materials, as well as various doping concentrations, should be further examined.

氧化钬 (Ho2O3) 陶瓷基磁光材料的法拉第效应测量

氧化钬的法拉第效应测量(Ho23) 本文介绍了陶瓷基磁光材料,这是高能激光法拉第隔离器的极具潜力的候选材料。非掺杂 Ho 的 Verdet 常数的温度依赖性23在 15–305 K 的温度下测量陶瓷$1.064~\unicode[STIX]{x03BC}\text{m}$波长。波长 0.5– 的 Verdet 常数色散$1~\unicode[STIX]{x03BC}\text{m}$$1.064~\unicode[STIX]{x03BC}\text{m}$测量了两个非掺杂的 Ho23陶瓷和何23掺铽 Tb 陶瓷3+(0.2 at. %) 和铈 Ce3+(0.1 at. %) 离子。结果表明,相对较低的 Ho 掺杂水平23这些离子对法拉第效应没有显着的促进作用。因此,Ho 的其他成分23应进一步研究基于陶瓷的磁光材料以及各种掺杂浓度。
