We investigate the subcycle control of electron trajectories in single ionization of Ar atoms with two-color laser pulses consisting of a linearly polarized 800-nm field and a circularly polarized 400-nm field. By varying the relative phase between t

The first hundred attoseconds of the electron dynamics during strong field tunneling ionization are investigated. We quantify theoretically how the electron's classical trajectories in the continuum emerge from the tunneling process and test the resu

We have combined a tandem mass spectrometer with a 780 nm fs-laser system to study photoionization and photofragmentation of trapped protonated leucine enkephalin cations for laser intensities between 2 × 1013 W/cm2 and 1 × 1014 W/cm2 and pulse dur

Channel-selective electron emission from strong-field photoionization of H_{2} molecules is experimentally investigated by using ultrashort laser pulses and a reaction microscope. The electron momenta and energy spectra in coincidence with bound and

Creation and survival of autoionizing states in strong laser fields

Autor: Thomas Pfeifer, Nicolas Camus, Joachim Ullrich, Andreas Krupp, Robert Moshammer, Lutz Fechner

Publikováno v: Physical Review A

Very sharp, low-energy structures observed in photoelectron spectra reveal the population of autoionizing states in krypton and argon in strong laser fields over a large range of different wavelengths. The energies of the electrons, emitted by autoio
