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…
Spiral-like Holographic Structures: Unwinding Interference Carpets of Coulomb-Distorted Orbits in Strong-Field Ionization
Andrew S Maxwell, XuanYang Lai, RenPing Sun +2
We unambiguously identify, in experiment and theory, a previously overlooked holographic interference pattern in strong-field ionization, dubbed "the spiral", stemming from two tra…
The effect of Coulomb field on laser-induced ultrafast imaging methods
XiaoLei Hao, YuXing Bai, XiaoYun Zhao +10
By performing a joint theoretical and experimental investigation on the high-order above-threshold ionization (HATI) spectrum, the dominant role of the 3rd-return-recollision traje…
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…
Understanding two-photon double ionization of helium from the perspective of the characteristic time of dynamic transitions
Fei Li, Facheng Jin, Yujun Yang +4
By using the B-spline numerical method, we investigate a two-photon double-ionization (TPDI) process of helium in a high-frequency laser field with its frequency ranging from 1.6~a…
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…
