Chipangizo choyamba cha laser cha attosecond cha ku China chikupangidwa

Chitchainachoyambachipangizo cha laser cha attosecondikumangidwa

Attosecond yakhala chida chatsopano kwa ofufuza kuti afufuze dziko lamagetsi. "Kwa ofufuza, kafukufuku wa attosecond ndi wofunikira, ndi attosecond, kuyesa kwa sayansi kochuluka mu njira yoyenera ya atomiki kudzakhala komveka bwino, anthu a mapuloteni a zamoyo, zochitika za moyo, sikelo ya atomiki ndi kafukufuku wina wofanana nawo adzakhala olondola kwambiri." Pan Yiming adatero.

Wei Zhiyi, wofufuza ku Institute of Physics of the Chinese Academy of Sciences, amakhulupirira kuti kupita patsogolo kwa ma pulse a coherent light kuchokera ku femtoseconds kupita ku attoseconds sikuti ndi kupita patsogolo kokha mu nthawi, koma chofunika kwambiri, kuthekera kwa anthu kuphunzira kapangidwe ka zinthu, kuyambira kuyenda kwa ma atomu ndi mamolekyu kupita mkati mwa ma atomu, kumatha kuzindikira kuyenda kwa ma elekitironi ndi machitidwe ena ofanana, zomwe zayambitsa kusintha kwakukulu mu kafukufuku woyambira wa fizikisi. Ndi chimodzi mwa zolinga zofunika kwambiri zasayansi zomwe anthu amatsata kuti ayesere molondola kuyenda kwa ma elekitironi, kuzindikira kumvetsetsa kwa makhalidwe awo akuthupi, kenako kuwongolera machitidwe amphamvu a ma elekitironi mu ma atomu. Ndi ma pulse a attosecond, titha kuyeza komanso kusintha tinthu tating'onoting'ono ta munthu payekha, motero kupanga zowonera zofunika kwambiri komanso zoyambirira ndi mafotokozedwe a dziko laling'ono kwambiri, dziko lolamulidwa ndi makina a quantum.

Ngakhale kuti kafukufukuyu akadali kutali pang'ono ndi anthu onse, kuyambitsa "mapiko a gulugufe" kudzatsogolera ku kubwera kwa kafukufuku wa sayansi "storm". Ku China, attosecondlaserKafukufuku wokhudzana ndi izi waphatikizidwa mu njira yofunika kwambiri ya chitukuko cha dziko, njira yoyenera yoyesera yamangidwa ndipo chipangizo cha sayansi chikukonzedwa, chipereka njira yatsopano yophunzirira mphamvu za attosecond, kudzera mu kuwona kayendedwe ka ma elekitironi, kukhala "maikulosikopu a elekitironi" abwino kwambiri m'gulu la nthawi yamtsogolo.

Malinga ndi chidziwitso cha anthu onse, attosecondchipangizo cha laserKukukonzekera ku Songshan Lake Materials Laboratory ku Guangdong-Hong Kong-Macao Greater Bay Area ku China. Malinga ndi malipoti, malo apamwamba opangira laser a attosecond amangidwa pamodzi ndi Institute of Physics of the Chinese Academy of Sciences ndi Xiguang Institute of the Chinese Academy of Sciences, ndipo Songshan Lake Materials Laboratory ikugwira ntchito yomanga. Kudzera mu kapangidwe ka malo oyambira, kumanga siteshoni ya mizere yambiri yokhala ndi ma frequency ambiri obwerezabwereza, mphamvu yayikulu ya photon, flux yayikulu komanso m'lifupi mwake wa pulse waufupi kwambiri kumapereka kuwala kolimba kwambiri komwe kumachepa kwambiri kuposa 60as ndi mphamvu yayikulu kwambiri ya photon mpaka 500ev, ndipo ili ndi nsanja yofufuzira yofananira, ndipo index yonse ikuyembekezeka kukhala mtsogoleri wapadziko lonse lapansi ikamalizidwa.
