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…
Bright 25-attosecond light pulses reach the one atomic unit of time
Jingsong Gao, Mahmudul Hasan, Hao Liang +8
Generating ever-shorter and brighter light pulses has long been a central pursuit in ultrafast science, as it benchmarks our ability to create and manipulate the coherence on the i…
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…
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…
