The recent developments of strong mid-infrared and terahertz light pulses have allowed electrons to be driven into a region far from the band edge, leading to high-order harmonics generation (HHG) by the field-driven carriers in the band structure [2-9]. However, despite their vital importance to frequency-mixing applications and the band reconstruction methodology, an angular and polarization selection rule for frequency-mixing processes in HHG induced by two-color optical fields has not yet been studied. Here, we observed HHG from a bulk crystal GaSe excited by orthogonally polarized two-color laser fields. Good agreement between the observed angle dependence and an analytical formula derived by taking into account the two-dimensional electron motion indicates that the one optical field amplifies the intraband nonlinear current driven with the other field and enhances the high-order harmonics (HHs). Our results provide the selection rule for frequency-mixing processes deformed by strongly driven carriers, which may lead to new technologies for polarization control and waveform synthesis of HHs with ultra-broadband spectra.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer Nature"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1038/s41467-020-16875-5","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.nature.com/articles/s41467-020-16875-5","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2041-1723","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"佐成晏之"}],"nameIdentifiers":[{"nameIdentifier":"872149","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"乙部, 智仁"}],"nameIdentifiers":[{"nameIdentifier":"872150","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"金光義彦"}],"nameIdentifiers":[{"nameIdentifier":"872151","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"廣理英基"}],"nameIdentifiers":[{"nameIdentifier":"872152","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Otobe, Tomohito","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"872153","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Modifying angular and polarization selection rules of high-order harmonics by controlling electron trajectories in k-space","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Modifying angular and polarization selection rules of high-order harmonics by controlling electron trajectories in k-space"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-04-12"},"publish_date":"2019-04-12","publish_status":"0","recid":"80086","relation_version_is_last":true,"title":["Modifying angular and polarization selection rules of high-order harmonics by controlling electron trajectories in k-space"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:50:54.355997+00:00"}
