Intense–field alignment of molecules confined in octahedral fields — •Toni Kiljunen1, Burkhard Schmidt2, and Nikolaus Schwentner1 — 1Institut für Experimentalphysik, FU-Berlin, Arnimallee 14, 14195 Berlin — 2Institut für Mathematik II, FU-Berlin, Arnimallee 2–6, 14195 Berlin
We investigate the combined effect of static octahedral potential and anisotropic interaction with intense, linearly polarized laser pulses on the rotational motion of linear molecules. Time–independent computations reveal a rich pattern of avoided crossings of energy levels corresponding to pendular states with different degree of alignment along the laser field polarization. Time–dependent computations put forward a scheme to manipulate the alignment by adiabatic and non–adiabatic passages through the avoided crossing regions, thus allowing for control over direction–dependent reaction mechanisms in solids.
