6.2-GW tabletop attosecond light source
Lihui Meng, Lu Xu, Xusheng Zhu +4
The generation of attosecond pulses (1 as=10-18 s) has enabled real-time observation and manipulation of coherent electron dynamics, yet their low peak power has hindered the devel…
Quantum Trajectory Separation and Attosecond Mapping in Liquid High-Harmonic Generation
Wanchen Tao, Ruisi Zhang, Qihe Guo +5
High-harmonic generation (HHG) from liquids offers a potential pathway to attosecond spectroscopy in chemically complex and disordered environments, yet fundamental questions remai…
Quantum Path Control in High-Order Harmonic Generation via Squeezed Lights
Feng Wang, Chunhui Yang, Xinyi Cui +6
High-order harmonic generation (HHG), a robust tabletop source for producing attosecond pulses, has been extensively utilized in attosecond metrology. Traditionally, HHG driven by…
Clean few-cycle blue soliton self-compressed pulses generation in hollow-core fibers
Ziping Huang, Jiale Peng, Weitao He +7
Blue pulses with few-cycle temporal durations hold significant value in attosecond science and ultrafast spectroscopy. In this work, we combine efficient broadband frequency doubli…
Unveiling unique ultrafast nonlinearities in liquid-phase high-order harmonic generation
Wanchen Tao, Zhuang-Wei Ding, Lixin He +5
High-order harmonic generation (HHG) provides a powerful optical tool for probing ultrafast dynamics on the attosecond timescale. While its mechanisms in gases and solids are well-…
"Molecular waveplate" for the control of ultrashort pulses carrying orbital angular momentum
Chengqing Xu, Lixin He, Wanchen Tao +8
Ultrashort laser pulses carrying orbital angular momentum (OAM) have become essential tools in Atomic, Molecular, and Optical (AMO) studies, particularly for investigating strong-f…
