Non-dipole effects in strong-field ionization are observed at high laser intensities and/or long wavelengths that both lead to high kinetic energies of the photoelectrons [1]. At longer wavelengths, the electron is influenced by the magnetic field component of the laser field even at moderate intensity [2]. In cases where the Coulomb field can be neglected, the magnetic field component is responsible...
Strong field ionization momentum distribution contains much information. The angular distribution indicates real tunneling delay time, the center shows ellipticity dependent Coulomb effects, and the longitudinal momentum spread challenges the assumption of zero initial momentum.
We present a study of features in photoelectron momentum distributions from strong-field ionization of noble gases for few-cycle pulses in the mid-infrared regime and assign characteristics to their classical and quantum mechanical origin.
We present approach and results of an angular streaking experiment with the attoclock method [1] that suggest the existence of a real tunneling time in strong field ionization of Helium. The results are compared with competing theories of tunneling time and show that the only theories that are compatible with the experimental results are the L armor time and a distribution of tunneling times with...
