Ikoranabuhanga n'iterambere rya laser za attosecond mu Bushinwa

Iterambere ry'ikoranabuhanga n'iterambere ryalaser za attosecondmu Bushinwa

Ikigo cya Fiziki, Ishuri Rikuru ry’Ubumenyi ry’Abashinwa, cyatangaje ibyavuye mu gupima 160 nk’ama-pulse ya attosecond yihariye mu 2013. Ama-pulse ya attosecond yihariye (IAPs) y’iri tsinda ry’ubushakashatsi yakozwe hashingiwe ku mikorere yo mu rwego rwo hejuru iyobowe na ma-pulse ya laser ya sub-5 femtosecond yatujwe na CEP, hamwe n’umuvuduko wo gusubiramo wa 1 kHz. Imiterere y’ama-pulse ya attosecond yagaragajwe na spectroscopy yo kugorora ya attosecond. Ibisubizo bigaragaza ko uyu murongo w’imirasire ushobora gutanga ama-pulse ya attosecond yihariye afite igihe cyo guhorora cya attosecond 160 n’uburebure bw’umurambararo bwa 82eV. Itsinda ryakoze iterambere mu gukora isoko ya attosecond n’ikoranabuhanga rya spectroscopy yo kugorora ya attosecond. Inkomoko y’urumuri rwa ultraviolet rwinshi rufite ubushobozi bwo kugaragaza attosecond izafungura amashami mashya yo gukoresha muri fiziki y’ibintu bivanze. Mu 2018, Ikigo cya Fiziki, Ishuri Rikuru ry’Ubumenyi ry’Abashinwa, nacyo cyatangaje gahunda y’ubwubatsi bw’igikoresho gipima igihe kirekire cyane gihuza amasoko y’urumuri ya attosecond n’ibipimo bitandukanye. Ibi bizafasha abashakashatsi gukora ibipimo by’imikorere y’igihe kirekire (attosecond to femtosecond time-resolved) mu bintu, ariko kandi bikagira umuvuduko n’ubushobozi bwo gukemura ikibazo cy’ikirere. Kandi bifasha abashakashatsi gusesengura no kugenzura imikorere ya elegitoroniki ikora mu buryo bwa microscopic ultrafast mu atome, molekile, ubuso n’ibikoresho bikomeye. Ibi bizatanga inzira yo gusobanukirwa no gushyira mu bikorwa ibintu bifatika birimo ubushakashatsi bwinshi nka fiziki, chimie na biology.

Mu 2020, Kaminuza y’Ubumenyi n’Ikoranabuhanga ya Huazhong yatanze igitekerezo cyo gukoresha uburyo bwo gupima no gusana neza imiyoboro ya attosecond binyuze mu ikoranabuhanga rya optique gating rishobora gusubizwaho inshuro nyinshi. Mu 2020, Ishuri Rikuru ry’Ubumenyi ry’Abashinwa ryatangaje kandi ko ryashoboye gukora imiyoboro ya attosecond yihariye binyuze mu gushushanya umuyoboro wa femtosecond pulse photoelectric binyuze mu gukoresha ikoranabuhanga rya dual-light selective pass-gate. Mu 2023, itsinda ryaturutse muri Kaminuza Nkuru y’Igihugu y’Ikoranabuhanga ry’Ingabo ryatanze igitekerezo cyihuse cyo kugaragaza imiyoboro ya attosecond yihariye, yitwa qPROOF, kugira ngo hamenyekane imiyoboro ya attosecond yihariye ifite umurambararo mwinshi.

Mu 2025, abashakashatsi bo mu Ishuri Rikuru ry’Ubumenyi ry’Abashinwa i Shanghai bakoze ubushakashatsi kulaserIkoranabuhanga ryo guhuza rishingiye kuri sisitemu yo guhuza igihe yubatswe ku giti cyayo, ituma habaho gupima igihe neza cyane no gusubiza ibitekerezo bya laser za picosecond mu gihe nyacyo. Ibi ntibyagenzuraga gusa igihe cya sisitemu mu cyiciro cya attosecond ahubwo byanazamuye uburyo bwo kwizerwa bwasisitemu ya lasermu gihe cy'imikorere y'igihe kirekire. Sisitemu yo gusesengura no kugenzura yakozwe ishobora gukora ikosora ry'igihe mu buryo bwihuse. Muri uwo mwaka, abashakashatsi banakoresheje laser za STOV (relativistic intensity spacetime vortices) kugira ngo bakore imirasire ya gamma-ray ya attosecond ifite umuvuduko wa angular lateral orbital.

Urwego rwa laser za attosecond ruri mu gihe cy’iterambere ryihuse, rikubiyemo ibintu byinshi kuva ku bushakashatsi bw’ibanze kugeza ku guteza imbere ikoreshwa ryarwo. Binyuze mu mbaraga z’amatsinda y’ubushakashatsi mu bya siyansi, kubaka ibikorwa remezo, gushyigikira politiki z’igihugu, n’ubufatanye bw’imbere mu gihugu no ku rwego mpuzamahanga n’ubuhahirane, imiterere y’Ubushinwa mu bijyanye na laser za attosecond izagira amahirwe menshi yo gutera imbere. Uko za kaminuza nyinshi n’ibigo by’ubushakashatsi bifatanya n’ubushakashatsi kuri laser za attosecond, itsinda ry’abahanga mu bushakashatsi mu bya siyansi bafite icyerekezo mpuzamahanga n’ubushobozi bwo guhanga udushya rizahingwa, bigateza imbere iterambere rirambye rya siyansi ya attosecond. Ikigo cy’igihugu cy’ubushakashatsi mu bya siyansi cya Attosecond kizanatanga urubuga rw’ubushakashatsi ku muryango w’abahanga mu bya siyansi kandi kigire uruhare runini mu iterambere rya siyansi n’ikoranabuhanga.
