Generation of high-fluence and high-intensity hard x-ray attosecond pulses at European XFEL
Ichiro Inoue, Ulrike Boesenberg, Rustam Rysov +41
The paper reports the generation of nanofocused hard‑x‑ray attosecond pulses at the European XFEL with peak intensities around 10^20 W/cm², verified via saturation of amplified spo…
High-power attosecond X-ray free-electron lasers: physics and design strategy
Chenzhi Xu, Jiawei Yan, Ye Chen +5
Attosecond pulses from X-ray free-electron laser (XFEL) have opened new opportunities for probing ultrafast electronic dynamics on the Angstrom--attosecond spatiotemporal scale. Mo…
Coherent Rydberg excitation of single atoms using a pulsed fiber amplifier
Ying-Wen Zhang, Yang Wang, Chen-Long Xu +2
In recent years, the growing scale of programmable neutral-atom arrays has led to an increasing demand for higher-power Rydberg excitation light. Although pulsed amplifiers deliver…
U-Net-based surrogate modeling for attosecond X-ray free-electron lasers
Yufei Wei, Bingyang Yan, Chenzhi Xu +2
Attosecond X-ray pulse generation in modern X-ray free-electron lasers relies on strongly compressed, precisely tailored electron bunches, making accurate diagnostics and control o…
AttoSHINE: Generation of continuous-wave terawatt-scale attosecond X-ray pulses at SHINE
Bingyang Yan, Chenzhi Xu, Si Chen +4
Attosecond X-ray pulses are a critical tool for tracking ultrafast electron dynamics in condensed matter, molecular systems, and strongly correlated materials. Recent breakthroughs…
Spatiotemporal shaping of attosecond X-rays with time-dependent orbital angular momentum
Chenzhi Xu, Jiawei Yan, Gianluca Geloni +2
Attosecond X-ray pulses are indispensable for exploring ultrafast phenomena in matter on Angstrom and attosecond scales. Here we propose a new method to realize spatiotemporal shap…
