摘　　要：激光诱导等离子体作为一种宽光谱辐射源,能够产生X射线、紫外、可见、红外、太赫兹以及微波波段的辐射,可应用于天体物理、惯性约束核聚变、生物医学、材料科学、光谱分析、环境工程、信息技术、超快技术、光刻技术、成像技术、雷达技术、半导体技术等众多领域,具有较高的实用价值。迄今为止,有关激光诱导等离子体辐射特性的文献报道大多集中于描述激光与物质在单一波段的相互作用,对辐射的产生机理还未完全掌握,对完整光谱的研究综述依然比较缺乏。从电磁辐射光谱及其辐射机制的角度,对激光诱导等离子体的辐射特性做出了系统的梳理分类,对国内外相关团队的研究成果进行了总结和分析,特别从不同视角探究了等离子体与光谱辐射之间的物理关系。介绍了激光诱导等离子体各个波段的辐射特点,并讨论了影响辐射的相关因素。最后,对红外波段和太赫兹波段的研究前景进行了展望。As a radiation source with the wide spectrum,laser-induced plasma can produce X-ray,ultraviolet,visible,infrared,terahertz,and microwave radiation.It has high practical value and can be used in astrophysics,inertial confinement fusion,biomedicine,materials science,spectral analyses,environmental engineering,information technology,ultrafast technology,lithography technology,imaging technology,radar technology,and semiconductor technology,etc.Up to now,most of the literatures about the radiation characteristics of laser-induced plasma concentrate on the interaction between lasers and matter in a certain wave band,while the mechanism of radiation production is not fully understood,and there is still a lack of comprehensive introductions of the researches on a wide spectrum.The radiation characteristics of laser-induced plasma are systematically classified from the point of view of both electromagnetic radiation spectra and radiation mechanisms in this review.The research results of relevant teams at home and abroad are summarized and analyzed,especially the physical relationship between plasma and spectral radiation is explored from different perspectives.The radiation characteristics of laser-induced plasma in various bands are introduced,and the related factors affecting the radiation are discussed.Finally,the research prospect of infrared band and terahertz band are prospected.
