Meeting moderator:Associate Professor Lv Hang, Institute of Atomic and Molecular Physics, Jilin University

Abstract：

     Atomic molecules in an intense laser field produce ultra-broadband coherent radiation covering terahertz, visible, extreme ultraviolet and even soft X-rays due to extreme non-linear interactions on timescales spanning picosecond, femtosecond and even attosecond. Combined with multiscale pump-probe technology, this makes it possible to detect and manipulate matter with ultra-high precision at optical field periods and even subperiods, promising to open up a new revolution in the fields of atomic molecules and photophysics, chemistry and biology. This presentation will briefly introduce the current development of research on coherent radiation of atomic molecules under strong laser fields in the context of the construction of the Multi-Time Scale Coherent Light Source at the National University of Defense Technology (NUDT), and in particular the progress of research on attosecond physics at NUDT.
