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%。
