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…
Complete suppression of the non-dipole drift effect in high harmonic generation
Hailang Wei, Xiaosong Zhu, Pengfei Lan +1
In high harmonic generation (HHG), non-dipole effects become increasingly significant at long driving wavelengths, as the magnetic field leads to a lateral drift of the continuum e…
Instantaneous optical selection rule for independent control of valley currents
Wanzhu He, Xiaosong Zhu, Liang Li +4
We reveal an instantaneous optical valley selection rule that illuminates the coupling between the instantaneous optical chirality of the driving laser field and the chirality of v…
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-…
