Abstract:
In science and technology, one always needs light sources over a broad spectral range. To study dynamics at the timescale of the motion of electrons and atoms in materials, light pulses of femtoseconds to attoseconds are required. In this talk, I will give an overview of what scientists have been able to achieve in new light sources in the last twenty some years utilizing the extreme nonlinearity of the interaction of intense lasers in a gaseous medium. The basic idea behind high-order harmonic generation and the subsequent emergence of attosecond pulses will be reviewed. Then I will present recent progress and challenges that are waiting for solutions.
Introduction of Prof. Chii-Dong Lin
Prof Chii-Dong Lin is a University Distinguished Professor of Kansas State University since 1990 and he is now the associated director of the J.R. Macdonald Laboratory. He received his bachelor’s degree in National Taiwan University in 1969 and then his Ph.D degree in University of Chicago(1974). Then he did his postdoc research in Harvard University (1974-1976). He joined Kansas State University in 1976 and worked in Physics Department up to now. In the past 20 years, he has worked mainly on the interaction of intense ultrafast laser with atom/molecule, high harmonic generation, attosecond science. His major scientific contributions include the development of molecular ionization theory (MO-ADK), the development of quantitative rescattering (QRS) theory, the proposal and demonstration of Laser Induced Electron Diffraction (LIED) method to study the dynamics of molecules with sub-angstrom’s spatial resolution and few-femtosecond temporal resolution. He has published more than 420 articles in peer-reviewed journals, including 7 papers in Science and Nature in recent years. His research work has been cited by more than 15000 times, with a H-index of 63.
