ChiChinesechekutangaattosecond laser mudziyoiri kuvakwa

Iyo attosecond yave chishandiso chitsva chevanoongorora kuongorora nyika yemagetsi."Kuvaongorori, kutsvagisa kweatosecond kunofanirwa, neatosecond, kuyedza kwakawanda kwesainzi mune yakakodzera atomic scale dynamics process kuchave kwakajeka, vanhu kune biological mapuroteni, zviitiko zvehupenyu, chiyero cheatomu uye kumwe kutsvagisa kwakabatana."Pan Yiming akadaro.

Wei Zhiyi, muongorori paInstitute of Physics of the Chinese Academy of Sciences, anotenda kuti kufambira mberi kwemapuruzi emwenje anowirirana kubva kufemtoseconds kuenda kumaattoseconds hakusi kungofambira mberi kuri nyore muchiyero chenguva, asi chinonyanya kukosha, kugona kwevanhu kudzidza. maumbirwo echinhu, kubva pakufamba kwemaatomu nemamorekuru kusvika mukati memaatomu, anogona kuona kufamba kwemaerekitironi nemafambiro ane hukama, izvo zvakakonzera shanduko huru mukutsvaga kwefizikisi yekutanga.Ndicho chimwe chezvinangwa zvesainzi zvakakosha izvo vanhu vanoteedza kuyera nemafambiro emaerekitironi, kuona kunzwisisa kwehunhu hwavo hwemuviri, uyezve kudzora mafambiro ane simba emaerekitironi mumaatomu.Tine attosecond pulses, tinogona kuyera uye kunyange kushandura zvidimbu zvidiki zvidiki, uye nekudaro togadzira zvakakoshesesa uye zvepakutanga zvakacherechedzwa uye tsananguro yenyika ine microscopic, nyika inotongwa nequantum mechanics.
Kunyange zvazvo tsvakurudzo iyi ichiri kure zvishoma kubva kuvanhu vose, kukurudzirwa kwe "butterfly mapapiro" zvechokwadi kuchatungamirira pakusvika kwekutsvakurudza kwesayenzi "dutu".MuChina, attosecondlasertsvakiridzo yakabatana yakaverengerwa mugwara rebudiriro rakakosha renyika, hurongwa hwekuyedza hwakakodzera hwakavakwa uye mudziyo wesainzi uri kurongwa, uchapa nzira yakakosha yekudzidza yeattosecond dynamics, kuburikidza nekuona kwema electron kufamba, ive yakanyanya kunaka. "electron microscope" mune ramangwana rekugadzirisa nguva chikamu.

Zvinoenderana neruzhinji ruzivo, an attosecondLaser mudziyoiri kurongwa paSongshan Lake Materials Laboratory kuChina kuGuangdong-Hong Kong-Macao Greater Bay Area.Sekureva kwemishumo, iyo yepamusoro attosecond laser nzvimbo inovakwa pamwe chete neInstitute of Physics yeChinese Academy yeSainzi uye Xiguang Institute yeChinese Academy yeSainzi, uye Songshan Lake Materials Laboratory inobatanidzwa mukuvaka.Kuburikidza neiyo yakakwirira yekutanga nzvimbo dhizaini, kuvakwa kweakawanda-beam chiteshi chiteshi chine yakakwirira yekudzokorora frequency, yakakwira photon simba, yakakwira flux uye yakanyanyisa kupfupika kwepurusi upamhi inopa ultrafine inopindirana nemwaranzi ine ipfupi pulse hupamhi isingasviki 60as uye yakakwirira photon simba kumusoro. kusvika ku500ev, uye yakashongedzerwa neinowirirana application yekutsvagisa chikuva, uye yakazara indekisi inotarisirwa kuwana mutungamiri wenyika mushure mekupedza.
