Abstract

The 8.3 at.% Yb-doped yttrium-scandium-aluminum garnet (YSAG) ceramics were fabricated by a modified reverse co-precipitation method followed by uniaxial and cold isostatic pressing, annealing in air and high-temperature sintering in vacuum. Spectroscopic and lasing properties were investigated in dependence on Y/Sc/Al ratio in ceramic composition. Optical transmission of Yb:YSAG ceramics in visible and near-infrared spectral range exceeds 80 % that indicates a high quality of the Yb:YSAG samples. Among all the ceramics, the Y_2.35Yb_0.25Sc_1.00Al_4.40O₁₂ composition demonstrates the best lasing performance and the highest slope efficiency up to 75 %.

Yb:YSAG 陶瓷：替代单晶体的极具吸引力的薄盘激光材料？

通过改进的反向共沉淀法，然后经过单轴和冷等静压、空气退火和真空高温烧结，制备出了 8.3 at.% 的掺镱钇钪铝石榴石（YSAG）陶瓷。根据陶瓷成分中 Y/Sc/Al 的比例，研究了其光谱和激光特性。在可见光和近红外光谱范围内，Yb:YSAG 陶瓷的光学透射率超过 80%，这表明 Yb:YSAG 样品的质量很高。在所有陶瓷中，Y2.35Yb0.25Sc1.00Al4.40O12 成分的激光性能最好，斜率效率最高，可达 75%。

期刊介绍： Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties. Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour. Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
