| Abstract: | The plasma filament induced by ultra-short intense laser pulses propagating in atmosphere can generate terahertz radiation,which has been a new terahertz radiation source.The new terahertz radiation source has been attracting enormous research interest.Firstly,the evolution and present situation of Terahertz radiation from ultra-short intense laser-induced atmosphere plasma filaments are summarized in detail;especially,the forming mechanisms of Terahertz radiation from femtosecond laser-induced atmosphere plasma filaments are analyzed and discussed detailly.In addition,the prospects of the new terahertz radiation source in application are also discussed,and the unsolved problems in future are given in this paper. |
