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 kwemapombi emwenje akabatana kubva kufemtoseconds kuenda kumaattoseconds hakusi kungofambira mberi kuri nyore muchiyero chenguva, asi zvinonyanya kukosha, kugona kwevanhu kudzidza chimiro chechinhu, kubva pakufamba kwemaatomu nemamorekuru kuenda mukati meiyo maatomu uye mafambiro ane hukama. shanduko 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 yakabatanidzwa mugwara rebudiriro rakakosha renyika, hurongwa hwekuyedza hwakakodzera hwakavakwa uye mudziyo wesainzi uri kurongwa, uchapa nzira yakakosha yekudzidza yeattosecond dynamics, kuburikidza nekuona kwekufamba kweelectron, inova yakanakisa "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 hupamhi inopa ultrafine inopindirana nemwaranzi ine pfupi pfupi pulse hupamhi isingasviki makumi matanhatu uye iyo yepamusoro photon simba inosvika 500ev, uye yakashongedzerwa inoenderana inoenderana application yekutsvaga chikuva, uye inotarisirwa kuzadzisa indekisi yepasirese.
