Control Of Atomic Single And Double Ionization Dynamics Using Orthogonally Polarized Two-Color Laser Pulses

Single- and double-ionization of neon with orthogonally polarized two-color (OTC) laser Yields is investigated using the COLTRIMS method. We study the influence of the long range Coulomb potential of the parent ion on the final momentum distribution of electrons emitted during single ionization. Furthermore, we investigate nonsequential double ionization in OTC fields and demonstrate that the electron-electron correlation is highly sensitive to the sub-cycle field shape of the OTC pulses, in agreement with recent theoretical predictions.
