In this paper, we present an analytic expression for an electric field describing a superluminal or subluminal femtosecond laser focus with orbital angular momentum. The analytic expression for a superluminal or subluminal laser focus is obtained through a diffraction integral, in which the focal length is replaced by a time-dependent focal length under the paraxial approximation, and the Fourier transformation. The speed and pulse duration of a laser focus are determined by the total group delay dispersion and a chromaticity parameter defined by the longitudinal chromatic aberration of a dispersive focusing optic. It is shown that it is possible to generate a several femtosecond superluminal orbital angular momentum laser focus in the focal region.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1364/OE.439377","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.osapublishing.org/oe/fulltext.cfm?uri=oe-29-20-31665&id=459200","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1094-4087","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":"Moon Jeong, Tae"}],"nameIdentifiers":[{"nameIdentifier":"1025044","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Bulanov, Sergey"}],"nameIdentifiers":[{"nameIdentifier":"1025045","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hadjisolomou, Prokopis"}],"nameIdentifiers":[{"nameIdentifier":"1025046","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Timur, Esirkepov"}],"nameIdentifiers":[{"nameIdentifier":"1025047","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Bulanov, Sergey","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1025048","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Timur, Esirkepov","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1025049","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":"Superluminal-subluminal orbital angular momentum femtosecond laser focus","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Superluminal-subluminal orbital angular momentum femtosecond laser focus"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-12-27"},"publish_date":"2021-12-27","publish_status":"0","recid":"84992","relation_version_is_last":true,"title":["Superluminal-subluminal orbital angular momentum femtosecond laser focus"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T18:03:58.645794+00:00"}
