高次谐波产生(High Harmonic Generation)是一种非线性光学现象,这种现象是在强激光场中发现的。在20世纪80年代,随着超短脉冲激光技术的发展,人们在气体中观察到了高次谐波产生现象,这标志着高次谐波产生技术的诞生。 2. 相关理论或原理 高次谐波产生的理论基础是量子力学和非线性光学。当气体原子在强激光场中被电离...
High-harmonic generation has been driving the development of attosecond science and sources. More recently, high-harmonic generation in solids has been adopted by other communities as a method to study material properties. However, so far high-harmonic g
ResearchOpen Access18 Dec 2024Communications Physics Volume: 7, P: 404 The attoscience of strong-field-driven solids This Perspective explores attosecond physics in solids, focussing on high harmonic generation and attosecond transient absorption and reflection spectroscopy. Combining physical realizations an...
Physics - Atomic PhysicsWe investigate high-harmonic generation in closed systems, using the two-level atom as a simplified model. By means of a windowed Fourier transform of the time-dependent dipole acceleration, we extract the main contributions to this process within a cycle of the driving ...
We report the high-order harmonic generation of 65 fs, 800 nm pulses and tunable pulses from optical parametric amplifier in the plasmas produced on the surfaces of the materials belonging to the sixth period of the periodic table (Bi and Pb). The optimization of the fluence of heating pulses...

D Seipt,B Kämpfer - 《Review of Modern Physics》 被引量: 13发表: 2011年 A scaling law of high-order harmonic generation Using a nonperturbative quantum electrodynamics theory of high-order harmonic generation (HHG),a scaling law of HHG is established.The scaling law states t... Y Wu,...
Our calculations for HHG by an H atom in an excited 2p-state demonstrate that the rate for recombination into a final state with a different value of m(=卤1), is higher for lower harmonic orders N, while for higher N (beyond the plateau domain) the difference vanishes. For species with...
High-harmonic generation in atomic gases has been studied for decades, and has formed the basis of attosecond science. Observation of high-order harmonics from bulk crystals was, however, reported much more recently, in 2010. This Review surveys the subs
