Velocity Map Imaging of Trajectory Controlled Above-Threshold Ionization Spectra of Xenon Using the Two-Color Field Technique — •Daniel Würzler, Max Möller, Frank Meyer, Max Sayler, and Gerhard G. Paulus — HIJ IOQ, Max-Wien-Platz 1, 07743 Jena

Recent research shows that adding a weak second harmonic field perpendicular to a strong fundamental beam provides the ability to control high harmonic generation by suppressing recombination of certain electron trajectories. In this study, a collinear interferometer is build in order to combine an ultrashort laser pulse with its second harmonic field in the target area. The setup is used to demonstrate control over electron trajectories of Xenon in above-threshold ionization.
