Attosecond angle-resolved photoelectron spectroscopy.
We report experiments on the characterization of a train of attosecond pulses obtained by high-harmonic generation, using mixed-color (XUV+IR) atomic two-photon ionization and electron detection on a velocity map imaging detector. We demonstrate that the relative phase of the harmonics is encoded both in the photoelectron yield and the angular distribution as a function of XUV-IR time delay, th...
متن کاملAttosecond photoelectron spectroscopy of metal surfaces.
Recent attosecond-streaking spectroscopy experiments [A. L. Cavalieri, Nature (London) 449, 1029 (2007)10.1038/nature06229] using copropagating extreme ultraviolet (XUV) and infrared (IR) pulses of variable relative delay have measured a delay of approximately 100 attoseconds between photoelectrons emitted by a single XUV photon from localized core states and delocalized conduction-band states ...
متن کاملAttosecond time-resolved photoelectron spectroscopy of surfaces
We discuss streaking time delays for photoemission from solid model surfaces as a function of the degree of the initial-wave-function localization and including the dynamical plasmon response to the motion of the photoelectron.
متن کاملMeasurement of attosecond XUV pulses generated with polarization gating by two-dimensional photoelectron spectroscopy
We report on our high speed camera designed for temporal characterization of attosecond pulses (1as =10s) generated with the polarization gating technique. The uniform external magnetic field applied on the timeof-flight spectrometer enlarges the acceptance angle (up to 65 for ~20-eV photoelectrons). By collecting twodimensional momentum images of the photoelectrons, which are ejected by the XU...
متن کاملSecondary electron cascade in attosecond photoelectron spectroscopy from metals
Synopsis In a recent attosecond photoelectron spectroscopy experiment from a metal surface [A. L. Cavalieri et al. Nature (London) 449, 1029 (2007)] a tail of unexplained low-energy electrons was measured. These electrons are shown to be due to electron-electron scatterings as the photoelectrons leave the metal. We develop a model for single scattering and a model based on cascade theory to des...
