Such studies have invariably involved the use of spectral filters or spectrally dispersive optical components that are inherently lossy and technically complex. Here we present a new technique for the spectral selection of near-threshold harmonics and their spatial separation from the driving beams without any optical elements. We discover the existence of a narrow phase-matching gate resulting from the combination of the non-collinear generation geometry in an extended medium, atomic resonances and absorption. Our technique offers a filter contrast of up to 104 for the selected harmonics against the adjacent ones and offers multiple temporally synchronized beamlets in a single unified scheme. We demonstrate the selective generation of 133, 80 or 56 nm femtosecond pulses from a 400-nm driver, which is specific to the target gas. These results open new pathways towards phase-sensitive multi-pulse spectroscopy in the vacuum- and extreme-ultraviolet, and frequency-selective output coupling from enhancement cavities."}],"extern":"1","type":"journal_article","publication":"Light: Science & Applications","date_created":"2023-08-10T06:37:25Z","doi":"10.1038/lsa.2016.170","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1038/lsa.2016.170"}],"publication_identifier":{"eissn":["2047-7538"]},"pmid":1,"month":"11","language":[{"iso":"eng"}],"article_type":"original","page":"e16170-e16170","date_updated":"2023-08-22T08:46:05Z","title":"In situ frequency gating and beam splitting of vacuum- and extreme-ultraviolet pulses","intvolume":"         5","year":"2016","date_published":"2016-11-01T00:00:00Z","citation":{"ieee":"R.
