摘要: 稀土离子掺杂的倍半氧化物陶瓷材料具有高热导率、低声子能量、高激光损伤阈值等优势,在固体激光领域具有巨大的应用潜力。本文采用化学共沉淀法合成了高纯度、低团聚Yb∶Lu2O3陶瓷粉体,在氧气气氛下预烧后,结合热等静压(HIP)烧结制备了具有高致密度、高透过率的5%(原子数分数)Yb∶Lu2O3透明陶瓷。陶瓷的平均晶粒尺寸小于1 μm,在1 100 nm波长处的透过率超过81%。在974 nm波长处吸收截面为~0.97×10-20 cm2,在1.08 μm波长处的发射截面为~0.39×10-20 cm2。采用976 nm半导体激光器泵浦Yb∶Lu2O3陶瓷,室温条件下实现了11.67 W的连续激光输出,对应的斜效率为55.3%,激光中心波长为1 080.1 nm。

Abstract: Rare-earth ions doped sesquioxide ceramics exhibit notable advantages, including high thermal conductivity, low phonon energy, and high laser damage threshold, thereby demonstrating significant potential for solid-state laser applications. Powders with high purity and low agglomeration were synthesized by chemical co-precipitation method, then 5% (atomic fraction) Yb∶Lu2O3 transparent ceramics with high density and high transparency were obtained through oxygen pre-sintering and hot isostatic pressing (HIP) sintering. The samples have an average grain size of less than 1 μm, and exhibit an in-line transmittance of above 81% at 1 100 nm. The absorption cross-section at 974 nm is ~0.97×10-20 cm2, and the emission cross-section at 1.08 μm is ~0.39×10-20 cm2. Using a 976 nm laser diode as the pump source, a continuous-wave (CW) laser output at 1 080.1 nm is achieved from the fabricated Yb∶Lu2O3 ceramics at room temperature, with a output power of 11.67 W and slope efficiency of 55.3%.
