报告简介:
In this presentation, I will talk about our experimental works of atoms and molecules in strong laser fields at Peking University. Especially, I will present the experimental progress on the strong-field tunneling ionization from both perspective of theory and application. With the advanced coincidence technique, we are able to perform high resolution measurements on photoelectron angular distributions of atoms in linearly and elliptically polarized fields, allowing us to measure the initial mom entum distributions at tunnel exit and the frustrated process. Then, I will talk about the nonadiabatic effect and sub-barrier phase effect on strong-field tunneling ionization. Particularly, I will introduce the double-pointer attoclock configuration to accurately measure the amplitude and phase of tunneling electron wave-packets. Finally, I will discuss the tunneling time delay, which is still one of a controversial topic of quantum tunneling.
