Strong-Field Photoelectron Interferometry with Near-Single-Cycle Yb Lasers
Mahmudul Hasan, Phi-Hung Tran, Jingsong Gao +8
The concept of using photoelectron interferometry in short laser fields to probe electron dynamics and target structures was introduced more than two decades ago. However, the qual…
Circular RABBITT goes under threshold
Vladislav V. Serov, Jia-Bao Ji, Meng Han +3
We introduce circular under-threshold RABBITT (cuRABBITT) as a new interferometric method to probe discrete electronic excitations in atoms with attosecond resolution. By combining…
Optical Interference Effect in Strong-field Electronic Coherence Spectroscopy
Eleanor Weckwerth, Andrew J. Howard, Chuan Cheng +6
We have investigated strong-field-induced electronic coherences in argon and molecular nitrogen ions created by high-intensity, few-cycle infrared laser pulses. This is a step towa…
Revisiting self-seeding mechanism by generating vector ultraviolet N lasing
Jingsong Gao, Yang Wang, Jiahao Dong +5
An intense femtosecond laser pulse can generate ultraviolet air lasing, offering a promising remote light source. A long-standing hypothesis is whether it is seeded by a self-gener…
Coherence from multiorbital tunneling ionization of molecules
C. H. Yuen, C. D. Lin
We present a simple and general coherence model for multiorbital tunnel ionization of molecules, which we incorporate into our previously developed density matrix approach for sequ…
Probing Vibronic Coherence in Charge Migration of Molecules Using Strong Field Sequential Double Ionization
C. H. Yuen, C. D. Lin
We propose a novel scheme for probing vibronic coherence in charge migration in molecules utilizing strong field sequential double ionization. To demonstrate the feasibility of thi…
