In this project, a carrier to envelope phase (CEP) stabilized mid-infrared light source is necessary to stabilize the CEP of the FEL. This light source is required to have the repetition frequency of about 20 MHz and the output energy of a few tens milliwatts. To meet these requirements, we are developing the mid-infrared light source based on the difference frequency generation driven by an ytterbium doped fiber laser system. Up to now, we have constructed a modelocked fiber laser oscillator with the frequency of 23.5 MHz, 3-W class preamplifier and 20-W class amplifier. We show the present status of developments of the laser system in this report.", "subitem_description_type": "Abstract"}]}, "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": "川瀬, 啓悟"}], "nameIdentifiers": [{"nameIdentifier": "904013", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "羽島, 良一"}], "nameIdentifiers": [{"nameIdentifier": "904014", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "永井, 良治"}], "nameIdentifiers": [{"nameIdentifier": "904015", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kawase, Keigo", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "904016", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Hajima, Ryoichi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "904017", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nagai, Ryoji", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "904018", "nameIdentifierScheme": "WEKO"}]}]}, "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": "conference paper", "resourceuri": "http://purl.org/coar/resource_type/c_5794"}]}, "item_title": "差周波中赤外光源のためのファイバーレーザーの開発", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "差周波中赤外光源のためのファイバーレーザーの開発"}]}, "item_type_id": "10003", "owner": "1", "path": ["2"], "permalink_uri": "https://repo.qst.go.jp/records/81116", "pubdate": {"attribute_name": "公開日", "attribute_value": "2020-08-25"}, "publish_date": "2020-08-25", "publish_status": "0", "recid": "81116", "relation": {}, "relation_version_is_last": true, "title": ["差周波中赤外光源のためのファイバーレーザーの開発"], "weko_shared_id": -1}
