Both are electromagnetic waves whose frequency and phase are controlled by humans. In this study, as a third form of oscillation, we aimed to generate optical pulses like a group of noises and to change the frequency and phase in a disorderly manner. On the other hand, the brightness and directionality, which are the characteristics of lasers, were ensured. The resonator that generates these pulses has been newly developed. The developed noise-like pulses have been successfully used to generate high-brightness white light with a broad wavelength spread from 1200 nm to 2100 nm and with high spectral flatness, using the high nonlinearity obtained from the developed noisy pulses. New effects and applications are confirmed, such as obtaining stability that surpasses that of similar conventional light sources that have been done with a single short pulse train.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"研究分野：光ファイバ","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_30001_file22":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"20K05370seika.pdf","format":"application/pdf","mimetype":"application/pdf","url":{"url":"https://kindai.repo.nii.ac.jp/record/2000314/files/20K05370seika.pdf"},"version_id":"fd3c1416-4cc2-4c23-b0ad-baabffa03f27"}]},"item_30001_funding_reference15":{"attribute_name":"助成情報","attribute_value_mlt":[{"subitem_award_numbers":{"subitem_award_number":"20K05370","subitem_award_uri":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-20K05370/"},"subitem_award_titles":[{"subitem_award_title":"新しい加工･計測領域を開拓する雑音状パルスレーザーの発振機序解明と実用化要素研究","subitem_award_title_language":"ja"},{"subitem_award_title":"Oscillation mechanism elucidation and practical use elemental technology research on noise-like pulse laser that develops new processing and measurement region","subitem_award_title_language":"en"}],"subitem_funder_names":[{"subitem_funder_name":"独立行政法人日本学術振興会","subitem_funder_name_language":"ja"},{"subitem_funder_name":"Japan Society for the Promotion of Science","subitem_funder_name_language":"en"}]}]},"item_30001_language10":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_30001_subject7":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"光ファイバ","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"ファイバレーザー","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"パルスレーザー","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"雑音状パルス","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"パルス群","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"フェムト秒パルス","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"広帯域光源","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"非線形光学効果","subitem_subject_language":"ja","subitem_subject_scheme":"Other"}]},"item_30001_title0":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"新しい加工･計測領域を開拓する雑音状パルスレーザーの発振機序解明と実用化要素研究","subitem_title_language":"ja"},{"subitem_title":"Oscillation mechanism elucidation and practical use elemental technology research on noise-like pulse laser that develops new processing and measurement region","subitem_title_language":"en"}]},"item_30001_version_type12":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_title":"新しい加工･計測領域を開拓する雑音状パルスレーザーの発振機序解明と実用化要素研究","item_type_id":"40001","owner":"42","path":["1697004343623"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-11-08"},"publish_date":"2023-11-08","publish_status":"0","recid":"2000314","relation_version_is_last":true,"title":["新しい加工･計測領域を開拓する雑音状パルスレーザーの発振機序解明と実用化要素研究"],"weko_creator_id":"42","weko_shared_id":-1},"updated":"2024-10-23T00:49:15.430903+00:00"}
