Popis: We report on recent developments in coherent control of ultrafast photoionization dynamics with ultrashort polarization-shaped bichromatic pulse sequences. In the experiments, a novel pulse shaping scheme for the generation of Bichromatic Carrier-Envelope phase-stable Polarization-tailored Supercontinuum (BiCEPS) fields is combined with high-resolution photoelectron tomography to create, manipulate and reconstruct three-dimensional free electron wave packets from atomic multiphoton ionization. Examples for coherent control with bichromatic polarization-shaped pulse sequences are presented, including the generation of unusual angular momentum superposition states, carrier-envelope phase control of directional photoemission, the creation and manipulation of photoelectron vortices and electron wave packets with odd-numbered rotational symmetry as well as studies on ultrafast Rydberg and spin-orbit wave packet dynamics.
