Strong-field nonsequential double ionization of Ar and Ne
We investigate the nonsequential double ionization (NSDI) of Ar and Ne based on quantitative rescattering theory (QRS). According to QRS theory, each elementary NSDI process can be calculated by multiplying the returning electron wave packet with appropriate differential electron-ion scattering cross sections. We include (e, 2e) and electron-impact excitation cross sections of Ar+ to obtain the...
متن کاملNonsequential Double Ionization of Atoms in Strong Laser Pulses
It is now possible to produce laser pulses with reproducible pulse shape and controlled carrier envelope phase. It is discussed how that can be explored in double ionisation studies. To this end we solve numerically the Schrödinger equation for a limited dimensionality model which nevertheless treats electron repulsion qualitatively correctly and allows to study correlation effects due to the C...
متن کاملNonsequential double ionization with few-cycle laser pulses.
We investigate differential electron momentum distributions in nonsequential double ionization with linearly polarized, few-cycle pulses, using a classical model based on a laser-assisted inelastic (e(-),2e(-)) rescattering mechanism. These yields, as functions of the momentum components parallel to the laser polarization, are highly asymmetric and strongly influenced by the phase difference be...
متن کاملCarrier-envelope phase dependence of nonsequential double ionization of H2 by few-cycle laser pulses
We studied the dependence of double ionization of H2 molecules on the carrierenvelope phase of a few-cycle laser pulse in the nonsequential double ionization regime. For short pulses at low intensities the strong dependence is due to the return energy of the rescattering electrons and the result may be used for determining the absolute value of the carrier envelope phase.
متن کاملLaser-assisted and laser-induced electron-impact ionization during nonsequential double ionization of He
Two-electron sum-momentum distributions from nonsequential double ionization of He in an intense laser field are analyzed. The results of a S-matrix calculation show that the inelastic scattering of the first electron with the residual ion is best considered as a ~internal! laser-induced impact ionization. The parallel component of the sum momentum is found to be largest when the prescattering ...
