  bibo_abstract:
  - We present the detailed analysis of a new two-pulse orientation scheme that achieves
    macroscopic field-free orientation at the high particle densities required for
    attosecond and high-harmonic spectroscopies (Kraus et al 2013 arXiv:1311.3923).
    Carbon monoxide molecules are oriented by combining one-colour and delayed two-colour
    non-resonant femtosecond laser pulses. High-harmonic generation is used to probe
    the oriented wave-packet dynamics and reveals that a very high degree of orientation
    (Nup/Ntotal = 0.73–0.82) is achieved. We further extend this approach to orienting
    carbonyl sulphide molecules. We show that the present two-pulse scheme selectively
    enhances orientation created by the hyperpolarizability interaction whereas the
    ionization-depletion mechanism plays no role. We further control and optimize
    orientation through the delay between the one- and two-colour pump pulses. Finally,
    we demonstrate a complementary encoding of electronic-structure features, such
    as shape resonances, in the even- and odd-harmonic spectrum. The achieved progress
    makes two-pulse field-free orientation an attractive tool for a broad class of
    time-resolved measurements.@eng
