Because of the interaction between the electron beam and FEL electromagnetic field, a maximum electron energy decrease of 16% was observed. The measured energy decrease was consistent with the measured FEL spectrum. An FEL micropulse energy of ~100 μJ with the expected few-cycle pulse duration at a wavelength of 11 μm was observed. This result is an important milestone for the high-extraction-efficiency FEL oscillator and will contribute to the strong-field physics of atoms and molecules","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IOP Publishing"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.35848/1882-0786/abb690","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://iopscience.iop.org/article/10.35848/1882-0786/abb690","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1882-0778","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":"Zen, Heishun"}],"nameIdentifiers":[{"nameIdentifier":"1001053","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ohgaki, Hideaki"}],"nameIdentifiers":[{"nameIdentifier":"1001054","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hajima, Ryoichi"}],"nameIdentifiers":[{"nameIdentifier":"1001055","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ryoichi, Hajima","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1001056","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":"Record high extraction efficiency of free electron laser oscillator","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Record high extraction efficiency of free electron laser oscillator"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-08-17"},"publish_date":"2020-08-17","publish_status":"0","recid":"80729","relation_version_is_last":true,"title":["Record high extraction efficiency of free electron laser oscillator"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:39:06.770698+00:00"}
