Coherent control of 6Li multiphoton ionization by a bichromatic laser field — •Silva Mezinska1, Klaus Bartschat2, Thomas Pfeifer1, and Alexander Dorn1 — 1Max-Planck-Institute for Nuclear Physics, Heidelberg, Germany — 2Drake University, Des Moines, Iowa, USA
This work presents a coherent 6Li multiphoton ionization control by a bichromatic laser field at 780/390 nm. In particular, we demonstrate a control of the left-right asymmetry of the photoelectron angular distributions with respect to the plane orthogonal to the laser polarization direction with a subwavelength accuracy. In addition, we also consider a delay scan between the two harmonics extending between the second-harmonic pulse advancing the fundamental pulse and vice versa. Here, we study the delay-dependent features of the photoelectron spectra when the two harmonics are temporally overlapping and non-overlapping. All the experimental results are compared with calculations based on the solution of the time-dependent Schrödinger equation in the single-active electron approximation.
