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 Ishuri Rikuru ry’Ubugenge ry’Ishuri Rikuru ry’Ubumenyi ry’Ubushinwa, yemeza ko iterambere ry’imisemburo yoroheje iva kuri femtosekond kugeza kuri attoseconds atari iterambere ryoroshye gusa mu gihe cyagenwe, ariko cyane cyane, ubushobozi bw’abantu kwiga imiterere yibintu, uhereye kumyuka ya atome na molekile kugera imbere muri atome, irashobora kumenya urujya n'uruza rwa electron hamwe nimyitwarire ifitanye isano, byateje impinduramatwara ikomeye mubushakashatsi bwibanze bwa fiziki.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 harateganijwe igikoresho cya siyansi, kizatanga uburyo bushya bwo guhanga udushya twiga imbaraga za attosekond, binyuze mu kureba icyerekezo cya electron, kibe cyiza "Electron microscope" murwego rwo gukemura igihe kizaza.

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, iyubakwa rya sitasiyo-yumurongo wa radiyo ifite inshuro nyinshi zisubiramo, ingufu za fotone nyinshi, flux nini nubugari bugufi cyane itanga imishwarara ya ultrafine coherent hamwe nubugari bugufi bwa pulse butarenze 60as hamwe ningufu za fotone ndende hejuru kugeza kuri 500ev, kandi ifite ibikoresho bijyanye nubushakashatsi bukoreshwa, kandi indangagaciro yuzuye iteganijwe kugera ku muyobozi mpuzamahanga nyuma yo kurangiza.
