Igikoresho cya mbere cya laser cyo mu Bushinwa kirimo gukorwa

Igishinwambereigikoresho cya laser cya attosecondirimo kubakwa

Pan Yiming yagize ati: “Ku bashakashatsi, ubushakashatsi bwa attosecond ni ngombwa, hamwe na attosecond, ubushakashatsi bwinshi bwa siyansi mu mikorere y’ibipimo bya atome buzaba busobanutse neza, abantu barebe poroteyine z’ibinyabuzima, imiterere y’ubuzima, ibipimo bya atome n’ubundi bushakashatsi bifitanye isano burusheho kuba bwiza.”

Wei Zhiyi, umushakashatsi mu Kigo cya Fiziki cy’Ishuri Rikuru ry’Ubumenyi bw’Abashinwa, yizera ko iterambere ry’urumuri ruhuza kuva kuri femtoseconds kugera kuri attoseconds atari intambwe yoroshye mu gihe, ahubwo ikiruta byose, ubushobozi bw’abantu bwo kwiga imiterere y’ibintu, kuva ku rujya n’uruza rwa atome na molekile kugera imbere muri atome, bushobora kumenya urujya n’uruza rwa electron n’imyitwarire bifitanye isano, byateje impinduka ikomeye mu bushakashatsi bw’ibanze bwa fiziki. Ni imwe mu ntego z’ingenzi za siyansi abantu bakurikirana kugira ngo bapime neza urujya n’uruza rwa electron, bamenye neza imiterere yazo, hanyuma bagenzure imikorere ya electron muri atome. Hamwe n’imivuduko ya attosecond, dushobora gupima ndetse no gukoresha utunyangingo twa microscopic ku giti cyacu, bityo tugakora isuzuma ry’ibanze kandi ry’umwimerere n’ibisobanuro by’isi ya microscopic, isi yiganjemo quantum mechanics.

Nubwo ubu bushakashatsi bukiri kure gato y’abaturage muri rusange, gushyira ahagaragara "amababa y'ikinyugunyugu" bizageza ku bushakashatsi bwa siyansi "inkubi y'umuyaga". Mu Bushinwa, attosecondlaserUbushakashatsi bujyanye nabyo bwashyizwe mu cyerekezo cy’ingenzi cy’iterambere ry’igihugu, sisitemu y’igerageza ijyanye nabyo yarubatswe kandi igikoresho cya siyansi kirimo gutegurwa, kizatanga uburyo bushya bw’ingenzi bwo kwiga imiterere ya attosecond, binyuze mu kwitegereza imikorere ya electron, kizaba "microscope ya electron" nziza mu cyiciro cy’igihe kizaza.

Dukurikije amakuru ya rubanda, umusegondaigikoresho cya laserBiteganyijwe ko muri Laboratwari y’ibikoresho bya Songshan Lake mu gace ka Guangdong-Hong Kong-Macao mu Bushinwa. Nk’uko amakuru abivuga, ikigo cy’ikoranabuhanga cya attosecond laser cyubatswe ku bufatanye n’Ikigo cya Fiziki cy’Ishuri Rikuru ry’Ubumenyi ry’Abashinwa n’Ikigo cya Xiguang cy’Ishuri Rikuru ry’Ubumenyi ry’Abashinwa, kandi Laboratwari y’ibikoresho bya Songshan Lake ifite uruhare mu bwubatsi. Binyuze mu gishushanyo mbonera cy’ahantu hirengeye, kubaka sitasiyo y’imirongo myinshi ifite frequency yo gusubiramo inshuro nyinshi, ingufu nyinshi za photon, flux nyinshi n’ubugari bugufi cyane bw’ingufu zitanga imirasire ihamye cyane ifite ubugari bugufi bwa pulse buri munsi ya 60as n’ingufu nyinshi za photon kugeza kuri 500ev, kandi ifite urubuga rw’ubushakashatsi rujyanye n’ibyo, kandi iki gipimo cyuzuye cyitezweho kugera ku isonga mpuzamahanga nyuma yo kurangiza.
