A laser resonator using a fiber has high stability and high efficiency. In addition, since a long fiber waveguide is used, nonlinearity is likely to occur. They can be used to generate short pulses in the femtosecond region. However, since the nonlinearity is high, a high output cannot be obtained. Therefore, the range of the application has been limited. To solve this problem, we have developed a technology that individually amplifies the pulses branched to multiple amplification fibers, aligns the phases of the light waves, and combines them. It has become possible to control the length of an optical fiber with a length of several tens of meters with an accuracy of several tens of nanometers. And the pulse addition was successful.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：基盤研究(C);  研究期間：2017～2019;   課題番号：17K05085;   研究分野：ファイバ光学   科研費の分科・細目：","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ(WEKO2)","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"},{"subitem_text_value":"連携研究者"},{"subitem_text_value":"連携研究者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Yoshida, Minoru"},{"subitem_text_language":"en","subitem_text_value":"Amano, Ryo"},{"subitem_text_language":"en","subitem_text_value":"Nskayama, Keizo"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学理工学部; 教授"},{"subitem_text_value":"近畿大学理工学部電気電子工学科; 助教"},{"subitem_text_value":"近畿大学理工学部電気電子工学科; 講師"}]},"item_8_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kindai University"},{"subitem_text_value":"Kindai University"},{"subitem_text_value":"Kindai University"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"吉田, 実"},{"creatorName":"ヨシダ, ミノル","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"天野, 亮"},{"creatorName":"アマノ, リョウ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"中山, 敬三"},{"creatorName":"ナカヤマ, ケイゾウ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-03-15"}],"displaytype":"detail","filename":"17K05085seika.pdf","filesize":[{"value":"941.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"17K05085seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/21438/files/17K05085seika.pdf"},"version_id":"818f44ad-5084-4109-919c-9f5e1c78da3c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ファイバレーザー","subitem_subject_scheme":"Other"},{"subitem_subject":"フェムト秒パルス","subitem_subject_scheme":"Other"},{"subitem_subject":"ファイバ中の位相制御","subitem_subject_scheme":"Other"},{"subitem_subject":"コヒーレント加算","subitem_subject_scheme":"Other"},{"subitem_subject":"コヒーレント共振","subitem_subject_scheme":"Other"},{"subitem_subject":"器結合","subitem_subject_scheme":"Other"},{"subitem_subject":"光ファイバ","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"全ファイバ型フェムト秒パルスレーザーの産業応用に資する高エネルギー化と髙安定化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"全ファイバ型フェムト秒パルスレーザーの産業応用に資する高エネルギー化と髙安定化","subitem_title_language":"ja"},{"subitem_title":"Research on high energy and high stabilization for all-fiber femtosecond pulsed lasers for industrial applications","subitem_title_language":"en"}]},"item_type_id":"8","owner":"3","path":["4613"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-03-15"},"publish_date":"2021-03-15","publish_status":"0","recid":"21438","relation_version_is_last":true,"title":["全ファイバ型フェムト秒パルスレーザーの産業応用に資する高エネルギー化と髙安定化"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-09-13T04:45:03.297631+00:00"}
