摘　　要：激光钕玻璃是大型高功率激光装置的核心增益介质。早在20世纪60年代初期,我国便开始了激光钕玻璃的研究工作。经过多年发展,我国激光钕玻璃的品种和型号不断丰富,制备工艺技术从坩埚熔炉发展到连续熔炼,产品尺寸也逐步发展到米级,满足了我国不同时期高功率激光装置的需求。本文重点回顾我国硅酸盐激光钕玻璃和磷酸盐激光钕玻璃的发展历程,梳理激光钕玻璃的关键制备技术,并对我国激光钕玻璃的应用情况进行简要介绍。Signature Since the invention of laser in 1960,laser technology has been widely used in many fields,such as scientific research,industrial processing,medical treatment,military confrontation,space exploration,and daily life.In the continuous development of laser technology,laser materials are key as core gain media.Laser glass is an important component of solid laser media and is an optical glass composed of a glass matrix and activated ions.The physicochemical and process characteristics of laser glass depend on the matrix glass,the spectral performance depends primarily on the activated ions,and the final laser properties are determined by both the glass composition and preparation process.To date,rare-earth ions,which are an important class of activated ions,have afforded multiwavelength laser outputs in a bulk glass matrix.Compared with other rare earth ion-doped glasses,Nd3+ions offer advantages such as multiple absorption lines in the UV and visible regions,large stimulated emission cross sections,and low thresholds for~1μm wavelength lasers.Therefore,neodymium-doped laser glass is the preferred gain medium for xenon lamppumped high-energy laser devices.Since the introduction of ruby laser in the early 1960s,glass science and technology workers in China have begun to analyze the possibility of generating lasers in a glassy state.In 1961,Snitzer of the American Optical Company publicly reported the results of generating laser using crown optical glass doped with neodymium oxide.On April 27,1963,Gan et al.generated laser using rodshaped neodymium glass measuringΦ3 mm×5 cm,which propelled scientific investigations into laser neodymium glass in China.In 1964,the Shanghai Institute of Optics and Fine Mechanics(SIOM)was established,and laser glass research was transferred from Changchun to Shanghai.Laser neodymium glass has been investigated for 60 years at the SIOM.The latter is one of the few facilities in the world that can master the entire technology of laser neodymium glass,from glass composition design
