摘要
介绍了基于超快激光的强场太赫兹波产生技术、探测技术及其在物质调控研究中的应用.强场太赫兹波的产生机制主要包括:晶体非线性效应、激光等离子体相互作用、太赫兹自由电子激光等.太赫兹波的探测技术包括:电光采样探测、空气偏压相干探测和单发探测等.最后介绍了强场太赫兹光源在物质调控研究中的应用,特别指出将强场太赫兹光源与第四代X射线光源相结合,在物性表征和调控方面具有广阔的应用前景.
The generation and detection technology of high-field terahertz wave based on ultrafast laser and its applications on matter manipulation are introduced.The mechanism of the generation of strong-field terahertz wave includes:nonlinear effects in crystals,laser plasma interaction,terahertz free electron laser,and so on.Terahertz detection technology includes:electro-optical sampling,air biased coherent detection,single-shot detection,and so on.Finally,the application of strong-field terahertz wave in matter manipulation is introduced.Especially,it is pointed out that the combination of strong-field terahertz sources and the fourth generation X-ray source has broad application prospects in the characterization and control of matter properties.
