TL;DR: In this article, a tomographic technique based on Photoelectron Angular Distributions (PADs) measured by Velocity-Map-Imaging (VMI) is presented to reconstruct the three-dimensional shape of ultrashort free electron wave packets obtained from 1+2 Resonance Enhanced Multi-Photon Ionization (REMPI) of potassium atoms.

TL;DR: In this paper, an evolutionary algorithm in a closed feedback loop has been used in order to find pulse shapes that maximize a given effect, and this scheme has been applied to the optimization of total alignment, and to the control of the temporal structure of the alignment transient within a revival.

TL;DR: In this paper, a theoretical approach to describe PADs from nonperturbative Resonance Enhanced Multi-Photon Ionization (REMPI) with ultrashort polarization-shaped laser pulses is presented and compared to experimental results.

TL;DR: In this article, a joint experimental and theoretical study on strong field photo-ionization of sodium atoms using chirped femtosecond laser pulses is presented, where different excitation pathways enabling control are identified by simultaneous ionization and measurement of photoelectron angular distributions employing the velocity map imaging technique.
