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∶Lu_(2)O_(3)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∶Lu_(2)O_(3)透明陶瓷。陶瓷的平均晶粒尺寸小于1μm,在1100 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)cm^(2),在1.08μm波长处的发射截面为~0.39×10^(-20)cm^(2)。采用976 nm半导体激光器泵浦Yb∶Lu_(2)O_(3)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1080.1 nm。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∶Lu_(2)O_(3)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 1μm,and exhibit an in-line transmittance of above 81%at 1100 nm.The absorption cross-section at 974 nm is~0.97×10^(-20)cm^(2),and the emission cross-section at 1.08μm is~0.39×10^(-20)cm^(2).Using a 976 nm laser diode as the pump source,a continuous-wave(CW)laser output at 1080.1 nm is achieved from the fabricated Yb∶Lu_(2)O_(3)ceramics at room temperature,with a output power of 11.67 W and slope efficiency of 55.3%.
