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.","lang":"eng"}],"publication":"Physical Review Letters","publication_status":"published","extern":"1","type":"journal_article","date_updated":"2023-08-22T09:02:56Z","volume":113,"publication_identifier":{"eissn":["1079-7114"],"issn":["0031-9007"]},"day":"11","year":"2014","article_type":"original","publisher":"American Physical Society","date_published":"2014-07-11T00:00:00Z","keyword":["General Physics and Astronomy"],"pmid":1,"scopus_import":"1","quality_controlled":"1","title":"Two-pulse field-free orientation reveals anisotropy of molecular shape resonance","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1311.3923"}],"oa_version":"Preprint","issue":"2","language":[{"iso":"eng"}],"intvolume":"       113"}
