Chipangizo choyamba cha laser cha attosecond cha China chikumangidwa

China woyambachipangizo cha laser cha attosecondikumangidwa

Attosecond yakhala chida chatsopano kwa ofufuza kuti afufuze dziko lamagetsi."Kwa ochita kafukufuku, kafukufuku wa attosecond ndi wofunika, ndi attosecond, kuyesa zambiri za sayansi pazochitika za atomiki kudzakhala zomveka bwino, anthu a mapuloteni achilengedwe, zochitika zamoyo, masikelo a atomiki ndi kafukufuku wina wokhudzana ndi izi."Pan Yiming adati.

Wei Zhiyi, wofufuza ku Institute of Physics of the Chinese Academy of Sciences, akukhulupirira kuti kupita patsogolo kwa mphamvu yolumikizana yowala kuchokera ku femtoseconds kupita ku attoseconds sikungopita patsogolo pang'onopang'ono mu sikelo ya nthawi, koma chofunikira kwambiri, kuthekera kwa anthu kuphunzira. kapangidwe ka zinthu, kuchokera kumayendedwe a ma atomu ndi mamolekyu kupita mkati mwa ma atomu, amatha kuzindikira kusuntha kwa ma elekitironi ndi machitidwe ogwirizana, omwe adayambitsa kusintha kwakukulu mu kafukufuku woyambira wa sayansi.Ndi chimodzi mwa zolinga zofunika za sayansi zomwe anthu amatsata kuti ayeze molondola kayendedwe ka ma electron, kuzindikira kumvetsetsa kwa thupi lawo, ndiyeno kulamulira khalidwe lamphamvu la ma elekitironi mu maatomu.Ndi ma attosecond pulses, timatha kuyeza komanso kuwongolera tinthu tating'onoting'ono tating'onoting'ono, ndipo potero timawona zofunikira kwambiri komanso zofotokozera za dziko losawoneka bwino, dziko lolamulidwa ndi makina a quantum.
Ngakhale kuti kafukufukuyu akadali patali pang'ono ndi anthu wamba, kulimbikitsidwa kwa "mapiko a butterfly" kudzatsogolera kufika kwa "mkuntho" wa kafukufuku wa sayansi.Ku China, attosecondlaserkafukufuku wokhudzana waphatikizidwa mu malangizo a dziko lofunikira lachitukuko, njira yoyenera yoyesera yamangidwa ndipo chipangizo chasayansi chikukonzedwa, chidzapereka njira yofunikira yophunzirira mphamvu za attosecond, kupyolera mukuwona kayendetsedwe ka electron, kukhala yabwino kwambiri. "Ma electron microscope" m'gulu lazosankha zamtsogolo.

Malinga ndi chidziwitso cha anthu, attosecondchipangizo cha laserikukonzekera ku Songshan Lake Materials Laboratory ku China ku Guangdong-Hong Kong-Macao Greater Bay Area.Malinga ndi malipoti, malo apamwamba a attosecond laser amamangidwa pamodzi ndi Institute of Physics ya Chinese Academy of Sciences ndi Xiguang Institute of the Chinese Academy of Sciences, ndipo Songshan Lake Materials Laboratory ikugwira nawo ntchito yomanga.Kupyolera mu mapangidwe apamwamba oyambira, kumangidwa kwa malo opangira mizere yambiri yobwerezabwereza, mphamvu zambiri za photon, kusinthasintha kwakukulu komanso kuphulika kwafupipafupi kwambiri kumapereka ma radiation a ultrafine ogwirizana omwe ali ndi mphamvu zazifupi kwambiri zosakwana 60as komanso mphamvu ya photon yapamwamba kwambiri. ku 500ev, ndipo ili ndi nsanja yofananira yofufuzira, ndipo mndandanda wathunthu ukuyembekezeka kukwaniritsa mtsogoleri wapadziko lonse akamaliza.
