摘　　要：倍半氧化物Lu_(2)O_(3)因具有优异的热力学性能、低声子能量和强晶体场等特点,成为近红外和中红外光谱(1~3μm)范围内的宽带发射高功率激光基体材料的优秀候选者之一,近年来受到人们的广泛关注。Lu_(2)O_(3)的熔点高达2450℃,单晶生长极为困难,限制了其应用发展。但Lu_(2)O_(3)属于立方晶系,具有光学各向同性,因此制备Lu_(2)O_(3)基透明陶瓷成为一种可行的方案。透明陶瓷可以在较低的温度下(晶体熔点的60%~80%)烧结制备大尺寸样品,同时烧结周期相较于晶体生长周期大幅缩减,更有利于大量生产,因此制备Lu_(2)O_(3)基透明陶瓷作为新型激光介质材料更有潜力被广泛应用于科学研究、工业生产和日常生活。本文总结了基于稀土离子(Nd^(3+)、Er^(3+)、Yb^(3+)、Tm^(3+)、Ho^(3+))掺杂的Lu_(2)O_(3)基激光透明陶瓷的制备工艺及其性能参数的最新研究进展。未来,Lu_(2)O_(3)基激光陶瓷的开发将聚焦在大尺寸、高功率输出、低散射特性、高热稳定性、复合结构设计等方面以推动高性能固体激光器的发展。Sesquioxide Lu_(2)O_(3) has excellent thermodynamic properties,low phonon energy and strong crystal field characteristics,making it one of the excellent candidates for wideband high-power laser matrix materials in the near-infrared and mid-infrared spectra(1~3μm),and attracting widespread attention in recent years.Since Lu_(2)O_(3) has a melting point of up to 2450℃,growing single crystal is extremely difficult,limiting its application development.However,Lu_(2)O_(3) belongs to the cubic crystal system and is optically isotropic,making Lu_(2)O_(3)-based transparent ceramics a viable option.Compared to single crystal,transparent ceramics can be sintered at lower temperatures(60%~80%of the melting point of crystals)to prepare large-size samples,while the sintering cycle is greatly reduced and more conducive to mass production,so the preparation of Lu_(2)O_(3)-based transparent ceramics as a new type of laser material has the potential for a wider range of applications in scientific research,industrial production and daily life.In this paper,the preparation technology and properties of Lu_(2)O_(3)-based laser transparent ceramics doped with rare earth ions(Nd^(3+),Er^(3+),Yb^(3+),Tm^(3+),Ho^(3+))are reviewed.In the future,the development of half-oxide Lu_(2)O_(3)-based laser ceramics will be focused on large size,high power output,low scattering characteristics,high thermal stability,and composite structure design to promote the development of highperformance solid-state lasers.
