Idivayisi yokuqala ye-laser ye-attosecond yaseShayina iyakhiwa

IsiShayinakuqalaidivayisi ye-laser ye-attosecondkusakhiwa

I-attosecond isibe ithuluzi elisha labacwaningi lokuhlola umhlaba we-elekthronikhi. “Kubacwaningi, ucwaningo lwe-attosecond luyinto ebalulekile, nge-attosecond, izivivinyo eziningi zesayensi enqubweni efanele ye-athomu scale dynamics zizocaca kakhudlwana, abantu bamaprotheni ebhayoloji, izenzakalo zokuphila, isikali se-athomu kanye nolunye ucwaningo oluhlobene luzoqondakala kakhudlwana.” kusho uPan Yiming.

UWei Zhiyi, umcwaningi e-Institute of Physics of the Chinese Academy of Sciences, ukholelwa ukuthi inqubekela phambili yama-pulse okukhanya ahambisanayo kusukela kuma-femtoseconds kuya kuma-attoseconds akuyona nje inqubekela phambili elula esikalini sesikhathi, kodwa okubaluleke kakhulu, ikhono labantu lokufunda isakhiwo sezinto, kusukela ekuhambeni kwama-athomu nama-molecule kuya ngaphakathi kwama-athomu, lingabona ukunyakaza kwama-electron kanye nokuziphatha okuhlobene, okubangele inguquko enkulu ocwaningweni oluyisisekelo lwe-physics. Kungenye yezinhloso zesayensi ezibalulekile abantu abaziphishekelayo ukulinganisa ngokunembile ukunyakaza kwama-electron, ukuqonda ukuqonda izakhiwo zawo zomzimba, bese belawula ukuziphatha okuguquguqukayo kwama-electron kuma-athomu. Ngama-pulse e-attosecond, singalinganisa futhi siphathe ngisho nezinhlayiya ezincane ngazinye, ngaleyo ndlela senze ukubonwa okuyisisekelo nokwangempela kanye nezincazelo zomhlaba omncane, umhlaba obuswa yi-quantum mechanics.

Nakuba lolu cwaningo lusaqhelelene kancane nomphakathi jikelele, ukugqugquzelwa “kwamaphiko ebhabhathane” ngokuqinisekile kuzoholela ekufikeni kocwaningo lwesayensi “isiphepho”. EShayina, i-attosecondi-laserUcwaningo oluhlobene lufakiwe esiqondisweni esibalulekile sentuthuko kazwelonke, uhlelo lokuhlola olufanele selwakhiwe futhi idivayisi yesayensi iyahlelwa, izohlinzeka ngezindlela ezibalulekile ezintsha zokufunda i-attosecond dynamics, ngokubuka ukunyakaza kwama-electron, ibe "yi-electron microscope" engcono kakhulu esigabeni sesisombululo sesikhathi esizayo.

Ngokusho kolwazi lomphakathi, i-attosecondidivayisi ye-laserKuhlelwa eSongshan Lake Materials Laboratory eGuangdong-Hong Kong-Macao Greater Bay Area eShayina. Ngokusho kwemibiko, isikhungo se-attosecond laser esithuthukisiwe sakhiwe ngokubambisana yi-Institute of Physics of the Chinese Academy of Sciences kanye ne-Xiguang Institute of the Chinese Academy of Sciences, kanti i-Songshan Lake Materials Laboratory ihilelekile ekwakheni. Ngomklamo wezindawo zokuqala eziphakeme, ukwakhiwa kwesiteshi somugqa we-multi-beam esinemvamisa ephezulu yokuphindaphinda, amandla aphezulu e-photon, i-flux ephezulu kanye nobubanzi obufushane kakhulu be-pulse buhlinzeka ngemisebe eqondile kakhulu enobubanzi obufushane be-pulse obungaphansi kwama-60as kanye namandla aphezulu e-photon afinyelela ku-500ev, futhi ifakwe ipulatifomu yocwaningo lwesicelo ehambisanayo, futhi inkomba ephelele kulindeleke ukuthi ifinyelele umholi wamazwe ngamazwe ngemuva kokuqedwa.
