Titel:

Role of high ponderomotive energy in laser induced non-sequential double ionization

The laser induced non-sequential double ionization (NSDI) of rare gas atoms in mid-infrared laser fields is studied experimentally and theoretically. We investigate electron-electron correlation at high recollision energies, experimentally achieving ponderomotive energies (U p, the average energy of a free electron in the laser field) six times higher than in the previous experiments. The contri-bution of the two main channels of NSDI in the photoelectron momentum distribution: (e,2e)-like double ionization and recollision-induced excitation with subsequent ionization (RESI), are shown to scale differently with increase of ponderomotive energy. While the photoelectron momentum space induced by the (e,2e)-channel expands with increasing the recollision energy, the peak of the RESI distribution stays confined, opening possibility to disentangle experimentally the contributions of different channels. We demonstrate that for argon both (e,2e) and RESI mechanisms contribute, with overwhelming role of (e,2e) channel at higher U p, while for neon (e,2e) is the main mechanism for NSDI in all investigated U p -range.
