Fig. 1. Schematic of the setup for attosecond high-resolution Fourier transform spectroscopy. The number of discrete bursts in an attosecond pulse train driven by 0.8-, 1.3-, and 2.0-μm lasers is directly measured using soft X-ray interferometry, by delaying one part of the HHG pulse with respect to itself with ultrahigh precision of 1.5 as.

Fig. 1 (a) The three-step model of HHG.5 Ionization (by tunneling through the Coulomb + laser field potential, blue arrow) launches an electron in the continuum, which is subsequently accelerated by the oscillatory NIR laser field. Along some of the trajectories (red arrow), the electron returns to the ionic core, and a recombination accompanied by the emission of coherent XUV/X-ray light

The significantly faster electron dynamics, which are ultimately responsible for the following structural changes, occur on an attosecond (1 attosecond = 10 -18 seconds) timescale, and its study requires the use of attosecond laser pulses.

2018-07-16 · The attosecond pulse passing through a metal filer is selected and recombined with the pump beam, which is derived from the main beam or the IR OPA at a central wavelength ranging from 1.1 μm to 2.6 μm. The attosecond beam and the pump beam are collinearly focused onto the target in PEEM to form the pump–probe configuration and realize 2012-08-30 · In section 1, we introduce unfamiliar readers to 'attophysics' and we present a short overview of the high-order harmonic generation process which is used to generate attosecond XUV pulses. In section 2 , we review the role of the spectral phase for the propagation of XUV wave packets. The first broad and in-depth overview of current research in attosecond nanophysics, covering the field of active plasmonics via attosecond science in metals and dielectrics to novel imaging techniques with the highest spatial and temporal resolution. 2019-08-26 · The long-standing scientific quest of real-time tracing electronic motion and dynamics in all states of matter has been remarkably benefited by the development of intense laser-based pulsed sources with a temporal resolution in the attosecond [1 attosecond = 10 −18 s] time scale. An attosecond is equal to 1000 zeptoseconds, or 1/1000 of a femtosecond. Because the next higher SI unit for time is the femtosecond (10−15 seconds), Attosecond time- resolved photoelectron spectroscopy of liquid water.
