H2 Double Ionization with Few-Cycle Laser Pulses

The temporal dynamics of double ionization of H2 has been investigated both experimentally and theoretically with few–cycle laser pulses. The main observables are the proton spectra associated to the H+ + H+ fragmentation channel. The model is based on the time–dependent Schrödinger equation and treats on the same level the electronic and nuclear coordinates. Therefore it allows to follow the u...

Nonsequential 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...

Molecular Double Ionization Using Strong Field Few-Cycle Laser Pulses.

We study strong field double ionization of a series of organic molecules by making use of coincidence detection of fragment ions. We measure the double ionization yield as a function of pulse duration, intensity, polarization, and molecular conjugation. For conjugated molecules we find strong enhancement in the double ionization rate over what one would expect on the basis of tunneling or multi...

Time-resolved sequential double ionization of D2 molecules in an intense few-cycle laser pulse

The kinetic energy spectra of D+ ions resulting from the sequential double ionization of D2 molecules in an intense few-cycle laser field are calculated. The D2 molecule is first ionized at its equilibrium distance, followed by further ionization of D2 + at larger internuclear separations. The time evolution of the nuclear wave packet is calculated including loss from ionization by the time-dep...

Time-resolved reaction imaging by intense few- cycle laser pulses and laser high-order harmonics

We discuss two novel approaches to visualize ultrafast dynamics of polyatomic molecules using few-cycle intense laser pulses and the high-order harmonics in the soft X-ray region, respectively. First, we present the real-time Coulomb explosion imaging of ultrafast isomerization of C2D2 by using intense fewcycle laser pulses (<10 fs, ~1 PW/cm, ~800 nm) to show that the hydrogen migration proceed...
