Laser pulse ionization of fixed-in-space H2O
(IOP Publishing, 2012-09)
We present a detailed study of the ionization probability of H2O induced by a short intense laser pulse. Within the strong-field approximation, we present total and differential ionization probabilities of the water molecule ...
Resonant-enhanced above-threshold ionization of atoms by XUV short laser pulses
(Elsevier Science, 2009-12)
Above-threshold ionization of atoms by XUV short laser pulses is investigated close to the resonant 1s–2p transitions. Both ab initio TDSE and a theoretical Coulomb–Volkov like theory are used to study the enhancement in ...
Above threshold ionization of atoms by resonant XUV laser pulses
(IOP Publishing, 2011-06)
Above-threshold ionization of atoms by XUV short laser pulses with frequencies close to the resonant 1s–2p transition is investigated. We present a theory based on a variational expression using trial wavefunctions for the ...
Gauge independent theory applied to a model of atomic ionization by an intense laser pulse
(Springer, 2011-10)
An explicitly gauge invariant strong field theory is introduced and tested using a model laser-atom interaction. The theory relies on a power series in the target potential. Transitions amplitudes are obtained by using a ...
Ionization of atomic hydrogen by an intense resonant laser pulse
(Institute of Physics Publishing, 2009-12)
The ionization of atomic hydrogen by an intense laser field resonant with the transition ls-Spo is studied. The intensity of the field is strong enough to make the Rabi oscillations important. The theoretical treatment of ...
Factorization of laser-pulse ionization probabilities in the multiphotonic regime
(IOP Publishing, 2013-09)
We present a detailed study of the ionization probability of H and H$_{2}^{+}$ induced by a short intense laser pulse. Starting from a Coulomb–Volkov description of the process we derive a multipole-like expansion where ...
Unitary model for atomic ionization by an intense laser pulse
(Institute of Physics Publishing, 2009-12)
A unitary model describing the electronic transitions in an atom interacting with a laser pulse is proposed. The model includes the initial state coupling with the continuum spectrum. Continuum-continuum transitions are ...
The effect of the Coulomb potential on subcycle interference of electron wave packets in atomic ionization by two-color laser pulses
(Iop Publishing, 2014-10)
We analyse the effect of the long-range potential of the ionic core on the photoelectron emission in atomic ionization by a linearly polarized subcycle sculpted laser pulse of two-colour components, where one frequency ...
