These observations have opened up the possibility of attosecond metrology in solids, which would benefit from a precise measurement of the emission times of individual harmonics with respect to the NIR laser field. Here we show that, when high-harmonics are detected from the input surface of a magnesium oxide crystal, a bichromatic probing of the XUV emission shows a clear synchronization largely consistent with a semiclassical model of electron–hole recollisions in bulk solids. On the other hand, the bichromatic spectrogram of harmonics originating from the exit surface of the 200 μm-thick crystal is strongly modified, indicating the influence of laser field distortions during propagation. Our tracking of sub-cycle electron and hole re-collisions at XUV energies is relevant to the development of solid-state sources of attosecond pulses.","lang":"eng"}],"issue":"14","date_published":"2020-06-17T00:00:00Z","publication_status":"published","extern":"1","date_updated":"2023-08-22T07:36:36Z","article_processing_charge":"No","month":"06","day":"17","type":"journal_article","status":"public","title":"Attosecond synchronization of extreme ultraviolet high harmonics from crystals","quality_controlled":"1","scopus_import":"1","publisher":"IOP Publishing","date_created":"2023-08-09T13:09:51Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa_version":"Preprint","oa":1,"article_number":"144003","_id":"13998","language":[{"iso":"eng"}],"citation":{"mla":"Vampa, Giulio, et al. “Attosecond Synchronization of Extreme Ultraviolet High Harmonics from Crystals.” <i>Journal of Physics B: Atomic, Molecular and Optical Physics</i>, vol. 53, no. 14, 144003, IOP Publishing, 2020, doi:<a href=\"https://doi.org/10.1088/1361-6455/ab8e56\">10.1088/1361-6455/ab8e56</a>.","ieee":"G.
