Abstract

The 8.3(3) at. % ytterbium-doped yttrium scandium aluminum garnet (Yb:YSAG) ceramics exhibit a high level of transmittance (over 80 %) in the infrared (IR) range, indicating its superior quality comparable to Yb:YAG single crystals. The Y_2.35Yb_0.25Sc_1.00Al_4.40O₁₂ laser ceramic sample achieved a maximum output power of 2.4 W at an absorbed pump power of 8.1 W at 325 K. In comparison, the 1 at.% Yb: YAG single crystal achieved a maximum output power of 3.9 W at an absorbed pump power of 13.6 W at 325 K. The laser radiation is linearly polarized, with a 90-degree rotation in polarization observed in only one ceramic sample at higher temperatures.

研究 325 至 400 K 温度范围内 Yb3+:YSAG 陶瓷和 YAG 单晶体发光特性的温度依赖性

8.3(3) at。掺镱钇钪铝石榴石（Yb:YSAG）陶瓷在红外（IR）范围内表现出高水平的透射率（超过80%），表明其质量优于Yb:YAG单晶。Y2.35Yb0.25Sc1.00Al4.40O12激光陶瓷样品在325 K吸收泵浦功率为8.1 W时，最大输出功率为2.4 W。相比之下，1 at。% Yb: YAG单晶在325 K时的最大输出功率为3.9 W，吸收泵浦功率为13.6 W。激光辐射是线性偏振的，在较高温度下仅在一个陶瓷样品中观察到90度的偏振旋转。
