Abstract
The strong-field dynamics of diatomic molecules with antibonding valence orbitals is investigated within classical and quantum mechanical model calculations. Due to the orbital symmetry, ejected electrons never return to the core if a linearly polarized laser field acts perpendicularly to the molecular axis. However, elliptical polarization can be used to achieve recollision so that high-order above-threshold ionization and high-order harmonic generation become maximal at nonzero ellipticity. Smaller ellipticities favour higher harmonic orders. For given ellipticity the probability for electron recollisions depends strongly on the orientation of the molecule. Thus, ellipticity can be used as a control parameter to select a range of orientations for recollision-induced processes.
