Laser diagnostics such as laser-induced breakdown spectroscopy (LIBS) makes it possible to monitor these parameters due to their fast response, high sensitivity, and non-contact features. In this study, a new collinear long and short double pulse LIBS method was developed to improve the detection ability and the measurement accuracy by the control of the plasma cooling process using the long pulse-width laser radiation. The plasma generated by the short pulse-width laser is stabilized and maintained at high temperature during the plasma cooling process by long pulse-width laser radiation. The method was demonstrated to have better measurement stability and quantitative measurement characteristics for Manganese and Carbon measurement in the steel samples compared to the normal single pulse LIBS method.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本光学会","subitem_publisher_language":"ja"}]},"item_10001_source_id_9":{"attribute_name":"収録物ID","attribute_value_mlt":[{"subitem_source_identifier":"03896625","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AN00080324","subitem_source_identifier_type":"NCID"}]},"item_10001_version_type_20":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_1715043197608":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access"}]},"item_1718868208704":{"attribute_name":"備考","attribute_value_mlt":[{"subitem_textarea_language":"ja","subitem_textarea_value":"著者英表記誤記あり　(誤)Mincho Cui→(正)Minchao Cui"}]},"item_1723180141928":{"attribute_name":"EID","attribute_value_mlt":[{"subitem_identifier_type":"URI","subitem_identifier_uri":"349350"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"出口, 祥啓","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"412","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wang, Zhenzhen","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Cui, Minchao","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"藤田, 裕貴","creatorNameLang":"ja"},{"creatorName":"フジタ, ユウキ","creatorNameLang":"ja-Kana"},{"creatorName":"Fujita, Yuki","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"田中, 誠也","creatorNameLang":"ja"},{"creatorName":"タナカ, セイヤ","creatorNameLang":"ja-Kana"},{"creatorName":"Tanaka, Seiya","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2020-04-28"}],"displaytype":"detail","filename":"kogaku_48_1_8.pdf","filesize":[{"value":"1.17 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://tokushima-u.repo.nii.ac.jp/record/2007385/files/kogaku_48_1_8.pdf"},"version_id":"6854cedc-40ad-443d-82c3-58344ec3e761"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"laser-induced breakdown spectroscopy","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"long and short double pulse LIBS","subitem_subject_language":"en","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ロングショートダブルパルスを用いたレーザーブレークダウン分光による元素定量分析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ロングショートダブルパルスを用いたレーザーブレークダウン分光による元素定量分析","subitem_title_language":"ja"}]},"item_type_id":"40001","owner":"7","path":["1713853295607"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2020-04-28"},"publish_date":"2020-04-28","publish_status":"0","recid":"2007385","relation_version_is_last":true,"title":["ロングショートダブルパルスを用いたレーザーブレークダウン分光による元素定量分析"],"weko_creator_id":"7","weko_shared_id":-1},"updated":"2024-10-30T09:19:26.816113+00:00"}
