Free-electron lasers and high-harmonic-generation table-top systems are new sources of
extreme-ultraviolet to hard X-ray photons, providing ultrashort pulses that are intense …

Three decades ago, a highly nonlinear nonpertubative phenomenon, now well-known as
the high harmonic generation (HHG), was discovered when intense laser irradiates gaseous …

摘要飞秒强激光与物质相互作用后辐射出的高次谐波, 具有单光子能量高, 脉冲持续时间短,

High harmonic generation (HHG) takes place in all phases of matter. In gaseous atomic and
molecular media, it has been extensively studied and is very well understood. In solids …

In this work, we decompose the high-harmonic generation (HHG) signal of aligned gas-
phase uracil into single molecular-orbital (MO) contributions. We compute HHG spectra for a …

High-order harmonic generation (HHG) in solid and gaseous targets has been proven to be
a powerful avenue for the generation of attosecond pulses, whereas the influence of …

High-order harmonic generation (HHG) in solids was expected to be efficient due to their
high density. However, the strict transition laws in crystals restrict the number of HHG …

By numerically solving the two-dimensional semiconductor Bloch equation, we study the
high-order harmonic emission of a monolayer ZnO under the driving of co-rotating two-color …

Considerable progress has been made in the experimental studies on laser-induced
terahertz (THz) radiation in liquids. Liquid THz demonstrates many unique features different …

High harmonic spectra for H 2 and H 2+ are simulated by solving the time-dependent Kohn–
Sham equation in the presence of a strong laser field using an atom-centered Gaussian …
