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"}],"quality_controlled":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication":"Physical Review Letters","date_published":"2014-07-11T00:00:00Z","day":"11","pmid":1,"month":"07","date_created":"2023-08-10T06:38:38Z","publication_identifier":{"issn":["0031-9007"],"eissn":["1079-7114"]},"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1311.3923"}],"article_processing_charge":"No","oa":1,"article_number":"023001","article_type":"original","oa_version":"Preprint","type":"journal_article","publisher":"American Physical Society","language":[{"iso":"eng"}],"issue":"2","extern":"1","scopus_import":"1","year":"2014","_id":"14020","doi":"10.1103/physrevlett.113.023001","author":[{"full_name":"Kraus, P. M.","first_name":"P. M.","last_name":"Kraus"},{"id":"71b4d059-2a03-11ee-914d-dfa3beed6530","first_name":"Denitsa Rangelova","last_name":"Baykusheva","full_name":"Baykusheva, Denitsa Rangelova"},{"full_name":"Wörner, H. J.","first_name":"H. J.","last_name":"Wörner"}],"status":"public","publication_status":"published","title":"Two-pulse field-free orientation reveals anisotropy of molecular shape resonance","date_updated":"2023-08-22T09:02:56Z","citation":{"mla":"Kraus, P.
