Mudziyo wekutanga weChina we attosecond laser uri kugadzirwa

ChiChinesechekutangamudziyo weattosecond laseriri kuvakwa

Attosecond yava chishandiso chitsva chevaongorori chekuongorora nyika yemagetsi. "Kune vaongorori, tsvakiridzo yeattosecond inofanirwa, neattosecond, kuyedza kwakawanda kwesainzi mumaitiro akakodzera eatomic scale dynamics kuchave kwakajeka, vanhu vemapuroteni ezvipenyu, zviitiko zvehupenyu, atomic scale nezvimwe tsvakiridzo zvine chekuita nazvo zvichave zvakanyatsojeka." Pan Yiming akadaro.

Wei Zhiyi, muongorori paInstitute of Physics yeChinese Academy of Sciences, anotenda kuti kufambira mberi kwekufamba kwechiedza kubva kumafemtoseconds kuenda kumaattoseconds hakusi kungofambira mberi kuri nyore muchiyero chenguva, asi chinonyanya kukosha, kugona kwevanhu kudzidza chimiro chezvinhu, kubva pakufamba kwemaatomu nemamorekuru kuenda mukati memaatomu, kunogona kuona kufamba kwemaerekitironi uye maitiro akafanana, izvo zvakakonzera shanduko huru mukutsvagisa kwefizikisi. Ndiyo imwe yezvinangwa zvakakosha zvesainzi zvinoteverwa nevanhu kuyera nemazvo kufamba kwemaerekitironi, kunzwisisa hunhu hwavo hwepanyama, uye kudzora maitiro anochinja emaerekitironi mumaatomu. Neattosecond pulses, tinogona kuyera uye kutoshandisa zvidimbu zve microscopic, uye nekudaro tichiita ongororo dzakakosha uye dzepakutanga uye tsananguro yenyika microscopic, nyika inotongwa nequantum mechanics.

Kunyangwe tsvakiridzo iyi ichiri kure zvishoma neveruzhinji, kukurudzirwa kwe "mapapiro eshavishavi" kuchatungamira pakusvika kwe "dutu" resainzi. MuChina, attosecondlaserTsvagiridzo dzakabatana dzakabatanidzwa mugwara rakakosha rekusimudzira nyika, sisitimu yekuedza yakakodzera yakavakwa uye chishandiso chesainzi chiri kurongwa, chichapa nzira itsva yekudzidza attosecond dynamics, kuburikidza nekutarisa kufamba kwemaerekitironi, kuve "electron microscope" yakanakisa muchikamu chekugadzirisa nguva mune ramangwana.

Zvinoenderana neruzivo rweveruzhinji, attosecondmudziyo welaserZviri kurongwa kuSongshan Lake Materials Laboratory muGuangdong-Hong Kong-Macao Greater Bay Area muChina. Sekureva kwemishumo, nzvimbo yepamusoro yeattosecond laser yakavakwa pamwe chete neInstitute of Physics of the Chinese Academy of Sciences neXiguang Institute of the Chinese Academy of Sciences, uye Songshan Lake Materials Laboratory iri kushanda mukuvaka. Kuburikidza nedhizaini yepamusoro yekutanga, kuvakwa kwechiteshi chemitsetse ine mabhanzi akawanda chine frequency yakakwira, simba re photon rakawanda, flux yakakwira uye pulse width pfupi kwazvo zvinopa mwaranzi yakapfava ine hupamhi hwe pulse hupfupi husingasviki 60as uye simba re photon rakakwirira rinosvika 500ev, uye ine puratifomu yekutsvagisa application inoenderana, uye indekisi yakazara inotarisirwa kusvika pakutungamira pasi rose mushure mekupedzwa.
