  bibo_abstract:
  - We report the observation of macroscopic field-free orientation, i.e., more than
    73% of CO molecules pointing in the same direction. This is achieved through an
    all-optical scheme operating at high particle densities (>10(17)  cm(-3)) that
    combines one-color (ω) and two-color (ω+2ω) nonresonant femtosecond laser pulses.
    We show that the achieved orientation solely relies on the hyperpolarizability
    interaction as opposed to an ionization-depletion mechanism, thus, opening a wide
    range of applications. The achieved strong orientation enables us to reveal the
    molecular-frame anisotropies of the photorecombination amplitudes and phases caused
    by a shape resonance. The resonance appears as a local maximum in the even-harmonic
    emission around 28 eV. In contrast, the odd-harmonic emission is suppressed in
    this spectral region through the combined effects of an asymmetric photorecombination
    phase and a subcycle Stark effect, generic for polar molecules, that we experimentally
    identify.@eng
