Chipangizo choyamba cha laser cha attosecond cha China chikumangidwa

Chitchainizichoyambachipangizo 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, amakhulupirira kuti kupita patsogolo kwa mphamvu yolumikizana yowala kuchokera ku femtoseconds kupita ku attoseconds sikungopita patsogolo pang'onopang'ono pamlingo wa nthawi, koma chofunikira kwambiri, kuthekera kwa anthu kuphunzira kapangidwe ka zinthu, kuchokera pakuyenda kwa ma atomu ndi mamolekyu kupita mkati mwa ma atomu omwe amatha kuzindikira ma atomu akulu ndi ma atomu ogwirizana. chisinthiko mu kafukufuku woyambira wa sayansi. Ndi chimodzi mwa zolinga zofunika za sayansi zomwe anthu amatsata kuti ayeze molondola kayendedwe ka ma elekitironi, 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 timazindikira zofunikira kwambiri komanso zofotokozera zapadziko lapansi, 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 wakhala m'gulu la dziko malangizo zofunika chitukuko, dongosolo zoyeserera zoyenerera wamangidwa ndi chipangizo sayansi ikukonzekera, adzapereka njira zofunika nzeru za phunziro la mphamvu attosecond, kudzera kuonerera mayendedwe elekitironi, kukhala yabwino "electron maikulosikopu" m'tsogolo gulu kusamvana nthawi.

Malinga ndi chidziwitso cha anthu, attosecondchipangizo cha laserikukonzekera ku Songshan Lake Materials Laboratory ku Guangdong-Hong Kong-Macao ku China ku Greater Bay Area. Malinga ndi malipoti, malo apamwamba a attosecond laser amamangidwa 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 nawo ntchito yomanga. Kupyolera mu mapangidwe apamwamba oyambira, kumanga malo opangira mizere ambiri omwe amakhala ndi ma frequency apamwamba, mphamvu ya photon yayikulu, kuthamanga kwambiri komanso kugunda kwafupipafupi kwambiri kumapereka ma radiation owoneka bwino kwambiri okhala ndi m'lifupi wamfupi kwambiri wosakwana 60as ndi mphamvu yapa photon yapamwamba kwambiri mpaka 500ev, ndipo imakhala ndi nsanja yofananira yofufuzira, ndipo mtsogoleri wapadziko lonse lapansi akuyembekezeka kukwaniritsa.
