In our scheme, we employed multi-pulse irradiation technique, where 16 pulse train, pulse width of each pulse: 100 ps (FWHM), pulse separation between each pulse: 200ps, and total energy: <3 J) were irradiated onto the Al slab target. The lasing of this transition was already demonstrated in a high-density and low-temperature Al laser plasma with a low gain coefficient. However, the gain coefficient was as low as 3.2 cm-1 at pump laser energy of 2 J. In order to improve the gain coefficient, we change the seed laser pulse from 100 ps to 400 ps for further heating the laser plasmas. Consequently, it was found that at the laser energy of 3 J, the gain coefficients (g~8.6, 5.5 cm^[-1}) were significantly improved by using longer seed pulse.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"The 11th International Conference on Inertial Fusion Sciences and Applications (IFSA 2019)","subitem_description_type":"Other"}]},"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":"Namba, Shinichi"}],"nameIdentifiers":[{"nameIdentifier":"812908","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"John, Chrisitain"}],"nameIdentifiers":[{"nameIdentifier":"812909","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kubo, Nobuyuki"}],"nameIdentifiers":[{"nameIdentifier":"812910","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kishimoto, Maki"}],"nameIdentifiers":[{"nameIdentifier":"812911","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsumoto, Yasauhiro"}],"nameIdentifiers":[{"nameIdentifier":"812912","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Morishita, Kakehiro"}],"nameIdentifiers":[{"nameIdentifier":"812913","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kakunaka, Noboru"}],"nameIdentifiers":[{"nameIdentifier":"812914","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hasegawa, Noboru"}],"nameIdentifiers":[{"nameIdentifier":"812915","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishikino, Masaharu"}],"nameIdentifiers":[{"nameIdentifier":"812916","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kishimoto, Maki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"812917","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hasegawa, Noboru","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"812918","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishikino, Masaharu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"812919","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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Observation of Gain Coefficient of 15.5 Nm Li-Like al Soft X-Ray Laser in a Recombining Plasma Pumped by a Compact YAG Laser","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Observation of Gain Coefficient of 15.5 Nm Li-Like al Soft X-Ray Laser in a Recombining Plasma Pumped by a Compact YAG Laser"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-10-29"},"publish_date":"2019-10-29","publish_status":"0","recid":"77229","relation_version_is_last":true,"title":["Observation of Gain Coefficient of 15.5 Nm Li-Like al Soft X-Ray Laser in a Recombining Plasma Pumped by a Compact YAG Laser"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:31:36.071982+00:00"}
