Stern-Gerlach type analysis of atoms excited by a strong laser field — •Sebastian Eilzer1, Thomas Nubbemeyer1, Karsten Gorling1, Ulli Eichmann1,2, and Wolfgang Sandner1,2 — 1Max-Born-Institut for Nonlinear Optics und Short Pulse Spectroscopy, Berlin, Germany — 2TU Berlin, Institut für Optik und Atomare Physik, Germany
Excitation of neutral atoms in strong laser fields in the tunnelling regime has recently been investigated [1]. A quantitative explanation of the process has been achieved by considering the ionic Coulomb potential in the three step model [2], which allows for bound trajectories. Based on the direct detection of excited neutral atoms we started a series of Stern-Gerlach type experiments. We placed emphasis on revealing possible spin effects in the interaction with the magnetic component of the strong laser field. We will discuss first experimental results.
