The fasaha da ci gaban trends na attosecond Laser a kasar Sin
Cibiyar nazarin ilimin lissafi, Cibiyar Kimiyya ta kasar Sin, ta ba da rahoton sakamakon ma'auni na 160 a matsayin keɓaɓɓen bugun jini a cikin 2013. Ƙwararren ƙwayar ƙwayar cuta (IAPs) na wannan ƙungiyar bincike an samar da su bisa ga babban tsari mai jituwa wanda aka yi ta hanyar ƙananan 5 femtosecond Laser bugun jini da aka daidaita ta hanyar CEP, tare da adadin kuzari 1. Halayen ɗan lokaci na bugun jini na attosecond an siffanta su ta hanyar duban gani na attosecond stretch spectroscopy. Sakamakon ya nuna cewa wannan katako na iya samar da keɓaɓɓen bugun jini na attosecond tare da tsawon lokacin bugun jini na 160 attoseconds da tsakiyar zangon 82eV. Ƙungiyar ta yi nasara a cikin ƙarni na farko na attosecond da kuma attosecond stretch spectroscopy technology. Matsanancin hasken ultraviolet tare da ƙuduri na biyu kuma zai buɗe sabbin filayen aikace-aikacen don ilimin kimiyyar kwayoyin halitta. A shekarar 2018, Cibiyar Nazarin Kimiya ta kasar Sin, Cibiyar Kimiyya ta kasar Sin, ta kuma ba da rahoton wani shiri na gina na'urar mai amfani da ma'aunin lokaci mai tsauri mai tsauri wanda ya hada hanyoyin hasken attosecond tare da tashoshi daban-daban. Wannan zai baiwa masu bincike damar gudanar da m attosecond zuwa femtosecond lokaci-tsare ma'auni na ultrafast matakai a cikin kwayoyin halitta, yayin da kuma samun lokaci da kuma sarari ƙuduri. Kuma yana ba masu bincike damar bincika da sarrafa ƙaramar ultrafast lantarki kuzarin kuzari a cikin zarra, kwayoyin halitta, filaye da ƙaƙƙarfan kayan. Wannan zai ba da hanya don fahimta da amfani da abubuwan da suka dace na macroscopic da suka shafi fannonin bincike da yawa kamar kimiyyar lissafi, sunadarai da ilmin halitta.
A cikin 2020, Jami'ar Kimiyya da Fasaha ta Huazhong ta ba da shawarar yin amfani da duk wata hanya ta gani don auna daidai da sake gina bugun jini a karo na biyu ta hanyar fasahar gating da aka warware akai-akai. A shekarar 2020, Cibiyar Nazarin Kimiyya ta kasar Sin ta kuma ba da rahoton cewa, ta samu nasarar samar da keɓancewar bugun jini a karo na biyu ta hanyar tsara filin lantarki na femtosecond na bugun jini ta hanyar yin amfani da fasahar zaɓe mai haske biyu. A cikin 2023, wata tawaga daga Jami'ar Tsaro ta Kasa ta ba da shawarar aiwatar da saurin PROF, wanda ake kira qPROOF, don keɓance nau'ikan ɓarke a karo na biyu.
A cikin 2025, masu bincike daga Kwalejin Kimiyya ta kasar Sin da ke Shanghai sun ɓullo da fasahar haɗin gwiwa ta Laser bisa tsarin daidaita lokaci mai zaman kansa, yana ba da damar ma'aunin madaidaicin lokacin jitter da amsa ainihin-lokaci na lasers picosecond. Wannan ba wai kawai sarrafa tsarin lokacin jitter a cikin kewayon attosecond ba amma kuma ya inganta amincin tsarin laser yayin aiki na dogon lokaci. Ƙididdigar haɓakawa da tsarin sarrafawa na iya yin gyare-gyare na lokaci-lokaci don jitter lokaci. A cikin wannan shekarar, masu binciken sun kuma yi amfani da na'urori masu ƙarfi na sararin samaniya (STOV) don samar da keɓantaccen bugun gamma-ray na biyu wanda ke ɗauke da motsin kusurwa na orbital na gefe.
Filin Laser na attosecond yana cikin saurin haɓakawa, yana rufe abubuwa da yawa daga bincike na asali zuwa haɓaka aikace-aikacen. Bisa kokarin da kungiyoyin binciken kimiyya suka yi, da gina ababen more rayuwa, da goyon bayan manufofin kasa, da hadin gwiwa da mu'amala da juna a cikin gida da na kasa da kasa, tsarin kasar Sin a fannin na'urar laser na biyu za ta samu kyakkyawan ci gaba. Yayin da ƙarin jami'o'i da cibiyoyin bincike ke shiga cikin bincike kan laser na biyu, za a haɓaka ƙungiyar ƙwararrun bincike na kimiyya tare da hangen nesa na ƙasa da ƙasa da sabbin damar damar, haɓaka ci gaba mai dorewa na kimiyyar attosecond. Babban cibiyar kimiyya ta Attosecond ta ƙasa kuma za ta samar da babban dandalin bincike ga al'ummar kimiyya tare da ba da babbar gudummawa ga ci gaban kimiyya da fasaha.
