Ikoranabuhanga niterambere ryiterambere rya lazeri ya attosecond mubushinwa

Ikigo cy’ubugenge, Ishuri ry’Ubumenyi ry’Ubushinwa, cyatangaje ibyavuye mu gupima 160 nk’imisemburo ya attosecond yitaruye mu mwaka wa 2013. Impiswi yihariye ya attosecond (IAPs) y’iri tsinda ry’ubushakashatsi yakozwe hashingiwe ku miterere yo mu rwego rwo hejuru itwarwa na sub-5 femtosekond laser pulses ihagaze neza na CEP, hamwe no gusubiramo inshuro 1 kHz. Ibiranga by'agateganyo impiswi ya attosecond yaranzwe na attosecond kurambura spekitroscopi. Ibisubizo byerekana ko iyi beamline ishobora gutanga impiswi yihariye ya attosecond hamwe na pulse yamara 160 ya attosekond hamwe nuburebure bwo hagati bwa 82eV. Iri tsinda ryateye intambwe mu kubyara isoko ya attosecond hamwe na tekinoroji ya attosekond. Umucyo ukabije ultraviolet urumuri rufite ibyemezo bya attosecond nabyo bizakingura imirima mishya yo gukoreshwa kubintu bifatika. Mu mwaka wa 2018, Ishuri Rikuru ry’Ubugenge, Ishuri Rikuru ry’Ubumenyi ry’Ubushinwa, naryo ryatangaje gahunda yo kubaka ibikoresho byifashishwa mu gupima ibikoresho bya ultrafast igihe byakemuwe n’ibikoresho bikoresha ibipimo bihuza amasoko y’umucyo wa attosecond hamwe n’ibipimo bitandukanye byo gupima. Ibi bizafasha abashakashatsi gukora attosecond yoroheje kuri femtosekond igihe cyakemuwe cyo gupima ibikorwa bya ultrafast mubintu, mugihe bifite imbaraga kandi zikemurwa. Kandi ituma abashakashatsi bakora ubushakashatsi no kugenzura microscopique ultrafast electronique ikora kuri atome, molekile, hejuru hamwe nibikoresho bikomeye. Ibi amaherezo bizatanga inzira yo gusobanukirwa no gushyira mubikorwa ibintu bifitanye isano na macroscopique ikubiyemo ibintu byinshi byubushakashatsi nka physics, chimie na biologiya.

Muri 2020, kaminuza y’ubumenyi n’ikoranabuhanga ya Huazhong yasabye ko hakoreshwa uburyo bwiza bwo gupima no kongera kubaka impiswi ya attosecond binyuze mu ikoranabuhanga ryakemuwe na optique. Mu mwaka wa 2020, Ishuri Rikuru ry’Ubushinwa naryo ryatangaje ko ryatsinze neza impiswi yihariye ya attosecond mu gushiraho umurima w’amafoto ya femtosekond ukoresheje amashanyarazi hifashishijwe ikoranabuhanga ry’amatara abiri. Mu 2023, itsinda ryaturutse muri kaminuza nkuru y’ingabo y’ikoranabuhanga ryasabye inzira yihuse ya PROOF, yitwa qPROOF, kugira ngo iranga ultra-Broadband yitaruye ya pulse ya attosecond.

Mu 2025, abashakashatsi bo mu Ishuri Rikuru ry’Ubumenyi ry’Ubushinwa muri Shanghai bateje imbere ikoranabuhanga rya laser syncronisation rishingiye kuri sisitemu yubatswe yigenga yigenga, ituma igihe cyo gupima igihe cyiza cyane hamwe n’ibitekerezo nyabyo byerekana lazeri ya picosekond. Ibi ntabwo byagenzuye gusa umwanya wa sisitemu mugihe cya attosecond ahubwo byanongereye ubwizerwe bwa sisitemu ya laser mugihe kirekire. Sisitemu yateye imbere yo kugenzura no kugenzura irashobora gukora igihe-cyo gukosora igihe cya jitter. Muri uwo mwaka, abashakashatsi banakoresheje lazeri ya relativistic ubukana bwimyanya ndangagitsina (STOV) kugirango babyare impanuka ya attosecond gamma-ray pulses itwara impande zombi za orbital.

Umwanya wa laseri ya attosecond uri mugihe cyiterambere ryihuse, ikubiyemo ibintu byinshi kuva mubushakashatsi bwibanze kugeza kuzamura porogaramu. Binyuze mu mbaraga z’itsinda ry’ubushakashatsi mu bya siyansi, kubaka ibikorwa remezo, gushyigikira politiki y’igihugu, ndetse n’ubufatanye bw’imbere mu gihugu ndetse n’amahanga ndetse no kungurana ibitekerezo, imiterere y’Ubushinwa mu bijyanye na laseri ya attosecond izagira amahirwe menshi y’iterambere. Mugihe kaminuza nyinshi nibigo byubushakashatsi bifatanya nubushakashatsi kuri laseri ya attosecond, hazashyirwaho itsinda ryimpano zubushakashatsi bwa siyanse zifite icyerekezo mpuzamahanga nubushobozi bushya bwo guhanga udushya, biteza imbere iterambere rirambye rya siyanse ya attosecond. Ikigo cy’igihugu cya Attosecond n’ubumenyi kizatanga kandi urubuga rw’ubushakashatsi ruyobora umuryango w’ubumenyi kandi rutange umusanzu munini mu iterambere rya siyansi n’ikoranabuhanga.
