过去的主要工作及获得的成果


强太赫兹辐射源的缺乏是目前限制太赫兹科学发展的主要瓶颈之一。针对这一科学难题,我们一直致力于研究如何利用超强激光与固体密度等离子体相互作用产生太赫兹辐射的新方案。经过多年探索,在太赫兹性能指标和物理机制两个方面,都取得了系列重要突破,获得了国际领先的强太赫兹辐射源。(1) 提出并实验验证了一种基于等离子体波的全新太赫兹产生机制,得到了当时国际先进的、单发强度大于200微焦/立体角的宽带太赫兹辐射;(2) 首次实验演示了基于激光-固体靶作用的太赫兹相干渡越辐射, 获得了单发能量近0.4毫焦的高亮太赫兹辐射,这已与传统大型加速器产生的太赫兹能量相当;(3) 创造了太赫兹脉冲能量的世界纪录。实验上利用大能量皮秒激光与金属薄膜靶相互作用获得了单发能量高达55毫焦的超强太赫兹脉冲,比之前公开报道的太赫兹脉冲最大能量高一个多数量级。现已发表第一作者论文8篇(其中包括2篇PRL和1篇PNAS),另作为主要作者合作发表论文30余篇;获中科院院长特别奖、蔡诗东等离子体物理奖、全球物理与天文学会优秀博士论文奖等荣誉。
