Igikoresho cya mbere cyabashinwa cya attosecond laser kirimo kubakwa

Igishinwambereigikoresho cya laseririmo kubakwa

Atosekond yabaye igikoresho gishya kubashakashatsi gushakisha isi ya elegitoroniki. Ati: "Ku bashakashatsi, ubushakashatsi bwa attosecond ni ngombwa, hamwe na attosecond, ubushakashatsi bwinshi bwa siyanse mu bikorwa bijyanye na dinamike ya atomike buzagenda busobanuka neza, abantu kuri poroteyine z'ibinyabuzima, ibinyabuzima, urugero rwa atome n'ubundi bushakashatsi bujyanye nabyo." Pan Yiming ati.

Wei Zhiyi, umushakashatsi mu kigo cy’ubugenge cy’ishuri ry’ubumenyi ry’Ubushinwa, yemeza ko iterambere ry’imisemburo yoroheje iva kuri femtosekond kugeza kuri attoseconds atari iterambere ryoroheje gusa mu gihe cyagenwe, ariko icy'ingenzi cyane, ni uko ubushobozi bw’abantu bwo kwiga imiterere y’ibintu, uhereye ku kugenda kwa atome na molekile kugeza imbere muri atome, bishobora gutahura urujya n'uruza rw'ibintu bya elegitoronike hamwe na moteri bifitanye isano na moteri. Nimwe mumigambi yingenzi yubumenyi abantu bakurikirana kugirango bapime neza imikorere ya electron, bamenye gusobanukirwa imiterere yumubiri wabo, hanyuma bagenzure imyitwarire yimikorere ya electron muri atome. Hamwe na pulse ya attosecond, turashobora gupima ndetse no gukoresha uduce duto twa microscopique, bityo tugakora ibintu byibanze kandi byumwimerere hamwe nibisobanuro byisi ya microscopique, isi yiganjemo ubukanishi bwa kwant.

Nubwo ubu bushakashatsi bukiri kure gato yabaturage muri rusange, gutangiza "amababa yikinyugunyugu" rwose bizatuma habaho ubushakashatsi bwa siyansi "umuyaga". Mubushinwa, attosecondlaserubushakashatsi bujyanye nabwo bwashyizwe mubyerekezo byingenzi byiterambere byigihugu, sisitemu yubushakashatsi ijyanye nayo yubatswe kandi harategurwa igikoresho cya siyansi, kizatanga uburyo bwingenzi bushya bwo kwiga imbaraga za attosecond, binyuze mu kureba icyerekezo cya electron, gihinduka "microscope ya electron" nziza mubyiciro bizaza.

Dukurikije amakuru rusange, attosecondigikoresho cya laserirategurwa muri Laboratwari y’ibiyaga bya Songshan mu Bushinwa bwa Guangdong-Hong Kong-Macao Greater Bay. Nk’uko amakuru abitangaza, ikigo cya lazeri cyateye imbere cyubatswe ku bufatanye n’ikigo cya fiziki cy’ishuri ry’ubumenyi ry’Ubushinwa n’ikigo cya Xiguang cy’ubumenyi bw’ubushinwa, kandi Laboratoire y’ibikoresho bya Lake Songshan igira uruhare mu iyubakwa. Binyuze mu gishushanyo mbonera cyo gutangiriraho, kubaka umurongo wa beam-imirongo myinshi ifite inshuro nyinshi zisubiramo, ingufu za fotone nyinshi, flux nini nubugari bugufi cyane bitanga imirasire ya ultrafine coherent ifite ubugari bugufi butarenze 60as hamwe ningufu za fotone ndende zigera kuri 500ev, kandi ifite ibikoresho byubushakashatsi bujyanye nibikorwa, kandi biteganijwe ko ibipimo ngenderwaho byuzuye bizagera kubayobozi mpuzamahanga nyuma yo kurangiza.
