Introduction:

Lai Yuheng, Special Research Assistant, Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences. Born in Hong Kong in 1989. Graduated from the Department of Physics, The Chinese University of Hong Kong, and later got a Ph.D. degree from the Department of Physics, Ohio State University. His research direction is the strong field ionization phenomenon of atoms and molecules. The tutors are Professor Louis DiMauro and Pierre Agostini. After graduating from the doctorate, he engaged in postdoctoral research for one year and then returned to work in Hong Kong. In November 2019, he joined the Guo Chunlei Photonics Laboratory of Changchun Institute of Optics and Mechanics, Chinese Academy of Sciences, and is mainly responsible for high-order harmonic research.

Research direction:

Strong field atomic and molecular physics; laser plasma high-order harmonics.

Abstract:

In this report, I first introduce the research I participated in during my research at Ohio State University, mainly discussing the strong field physical phenomena of different types of atoms (noble gases, metal atoms) and molecules in the near-infrared and mid-infrared laser wavelengths, including Strong field ionization under a wide range of Keldysh parameters, non-sequential double ionization under circularly polarized light, low-energy peaks in the photoelectron spectrum, high-energy electron re-scattering, etc. Then I will introduce the research work of laser plasma high-order harmonics that I am currently participating in Changchun Institute of Optics, Fine Mechanics and Physics.
