Imaging molecular orbitals with laser-induced electron tunneling spectroscopy
XuanYang Lai, RenPing Sun, ShaoGang Yu +4
Photoelectron spectroscopy in intense laser fields has proven to be a powerful tool for providing detailed insights into molecular structure. The ionizing molecular orbital, howeve…
Laser Driven Fluorescence Emission in a Nitrogen Gas Jet at 100 MHz Repetition Rate
Jin Zhang, LinQiang Hua, ShaoGang Yu +5
We report the fluorescence emission which is driven by femtosecond laser pulses with a repetition rate of 100 MHz and a center wavelength of 1040 nm in a nitrogen gas jet. The expe…
Laser-induced Electron-Transfer in the Dissociative Multiple Ionization of Argon Dimers
YanLan Wang, XuanYang Lai, ShaoGang Yu +12
We report on an experimental and theoretical study of the ionization-fragmentation dynamics of argon dimers in intense few-cycle laser pulses with a tagged carrier-envelope phase.…
Long range dipole-dipole interaction in atomic vapors probed by double-quantum two-dimensional coherent spectroscopy
Shaogang Yu, Michael Titze, Yifu Zhu +2
Optical double-quantum two-dimensional coherent spectroscopy (2DCS) was implemented to probe interatomic dipole-dipole interactions in both potassium and rubidium atomic vapors. Th…
Observation of scalable and deterministic multi-atom Dicke states in an atomic vapor
Shaogang Yu, Michael Titze, Yifu Zhu +2
Dicke state, a coherent state of multiple particles, is fundamentally responsible for various intriguing collective behaviors of many-body systems. Experimental access to Dicke sta…
Disentangling intra-cycle interferences in photoelectron momentum distributions using orthogonal two-colour laser fields
Xinhua Xie, Tian Wang, ShaoGang Yu +7
We use orthogonally polarized two-colour (OTC) laser pulses to separate quantum paths in multiphoton ionization of Ar atoms. Our OTC pulses consist of 400~nm and 800~nm light at a…
Near-threshold photoelectron holography beyond the strong-field approximation
XuanYang Lai, ShaoGang Yu, YiYi Huang +5
We study photoelectron angular distributions (PADs) near the ionization threshold with a newly developed Coulomb quantum-orbit strong-field approximation (CQSFA) theory. The CQSFA…
