摘要: 倍半氧化物Lu2O3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(1~3 μm)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。Lu2O3的熔点高达2 450 ℃,单晶生长极为困难,限制了其应用发展。但Lu2O3属于立方晶系,具有光学各向同性,因此制备Lu2O3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Lu2O3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(Nd3+、Er3+、Yb3+、Tm3+、Ho3+)掺杂的Lu2O3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,Lu2O3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。

Abstract: Sesquioxide Lu2O3 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 (1~3 μm), and attracting widespread attention in recent years. Since Lu2O3 has a melting point of up to 2 450 ℃, growing single crystal is extremely difficult, limiting its application development. However, Lu2O3 belongs to the cubic crystal system and is optically isotropic, making Lu2O3-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 Lu2O3-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 Lu2O3-based laser transparent ceramics doped with rare earth ions (Nd3+, Er3+, Yb3+, Tm3+, Ho3+) are reviewed.In the future, the development of half-oxide Lu2O3-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 high-performance solid-state lasers.
