Key properties of quantum materials stem from dynamic interaction chains that connect
stable electronic quasiparticles through short-lived coherences, which are difficult to control …

Pulse laser has been widely used in both fundamental science and practical technologies.
In this perspective, we highlight the employment of pulse laser ablation in air (LAA) in …

According to the three-step model for solid high-order harmonic generation, there is a one-to-
one correspondence between the emitted photon energy and the band gap where the …

Research on the interactions between optical solitons is of great significance for the large
capacity and long distance transmission in optical fibers. In this paper, interactions between …

By numerically solving the semiconductor Bloch equation, we study the high-order harmonic
emission spectrum of a MgO crystal under the interaction of a linearly polarized laser pulse …

When a bulk solid is irradiated by an intense laser pulse, transition dipole moments (TDMs)
between different energy bands have an important influence on the ultra-fast dynamic …

The photoelectron emission spectra generated by the interaction between ultrashort intense
laser pulses and atoms can reveal the ultrafast dynamics of electrons. By using the …

Cooper minimum structure of high-order harmonic spectra from atoms or molecules has
been extensively studied. In this paper, we demonstrate that the crystal harmonic spectra …

We propose an all-optical method to reconstruct the transition dipole moment of solid
materials. Our method is realized by high-order harmonic generation driving by a multicycle …

A series of theoretical and experimental results has proved that harmonics below/above the
band gap are produced mainly by the intraband current/interband polarization for solids in …
