摘　　要：采用激光二极管直接泵浦中红外激光材料的激光器具有系统简单、转换效率高及激光光束质量好等优势,受到越来越广泛的关注。目前,常用的激光材料如玻璃、晶体、单相多晶透明陶瓷均存在不足。具有优异的光学、热学及力学性能的纳米复相陶瓷成为了中红外激光器的理想激光材料。本文介绍了Y_(2)O_(3)–MgO纳米复相陶瓷的性能,同时概述了其新型的制备方法、性能优化思路以及稀土离子掺杂中红外激光基质材料的研究现状,并对Y_(2)O_(3)–MgO纳米复相陶瓷作为中红外激光基质材料的发展前景做了展望与分析。The 3–5μm mid-infrared laser can be used in infrared countermeasures,biomedicine,atmospheric remote sensing and environmental monitoring.All solid-state lasers using LD directly pumped laser materials become a main output method for mid infrared lasers due to their advantages like simple system,high conversion efficiency,and good beam quality.Polycrystalline transparent ceramics are commonly used as laser materials due to their preparation easiness,superior thermal and mechanical properties as well as the ability to achieve high doping concentrations.However,the development of high-power lasers requires overcoming the inevitable thermal effects during laser operation,i.e.,thermal birefringence,thermal lensing,and depolarization,which arise from the temperature gradient inside the laser material.It is crucial to use laser materials with a high thermal conductivity to alleviate thermal effects and ensure the quality and stability of laser output.Moreover,laser host materials must also have a lower phonon energy to suppress non-radiative transition processes that compete with the luminescence processes.It is thus difficult for materials to simultaneously possess all of these properties.In recent years,a large number of reports have claimed that Y_(2)O_(3)–MgO nanocomposite ceramics have ideal properties required for laser host materials,including high infrared transmittance,low phonon energy,high thermal conductivity,and good mechanical properties.The microstructure and properties of Y_(2)O_(3)–MgO nanocomposite ceramics doped with rare-earth activation ions are investigated,indicating that nanocomposite ceramics can be used as potential host materials for mid infrared lasers.This review summarized the existing research results of Y_(2)O_(3)–MgO nanocomposite ceramics as a laser host material and also represented recent technologies and methods for preparing Y_(2)O_(3)–MgO nanocomposite ceramics.The existing studies by theoretical models and experiments indicate that Y_(2)O_(3)–MgO nanocomposite ceramic
