Hanyoyin fasaha da ci gaba nalasers na attoseconda China
Cibiyar Nazarin Lissafi, Kwalejin Kimiyya ta Sin, ta ba da rahoton sakamakon aunawa na 160 a matsayin bugun attosecond da aka ware a shekarar 2013. An samar da bugun attosecond da aka ware (IAPs) na wannan ƙungiyar bincike bisa ga manyan harmonics da aka jagoranta ta hanyar bugun laser na femtosecond na ƙasa da 5 wanda CEP ya daidaita, tare da saurin maimaitawa na 1 kHz. An siffanta halayen lokaci na bugun attosecond ta hanyar gwajin attosecond. Sakamakon ya nuna cewa wannan layin beamline na iya samar da bugun attosecond da aka ware tare da tsawon bugun attosecond na 160 da kuma tsawon rai na tsakiya na 82eV. Ƙungiyar ta sami ci gaba a cikin samar da tushen attosecond da fasahar spectroscopy mai shimfiɗa attosecond. Tushen hasken ultraviolet mai ƙarfi tare da ƙudurin attosecond kuma za su buɗe sabbin filayen aikace-aikace don kimiyyar lissafi mai rikitarwa. A cikin 2018, Cibiyar Nazarin Lissafi, Kwalejin Kimiyya ta Sin, ta kuma ba da rahoton shirin gini don na'urar mai amfani da aunawa mai sauri-lokaci wacce ke haɗa tushen hasken attosecond tare da tashoshin aunawa daban-daban. Wannan zai ba masu bincike damar gudanar da ma'aunin sassauƙa na attosecond zuwa femtosecond wanda aka warware a lokaci-lokaci na hanyoyin ultrafast a cikin abubuwa, yayin da kuma ke da ƙarfin motsi da ƙudurin sarari. Kuma yana ba masu bincike damar bincika da kuma sarrafa ƙananan ƙwayoyin lantarki masu saurin gaske a cikin ƙwayoyin halitta, ƙwayoyin halitta, saman da kayan ƙarfi masu yawa. Wannan a ƙarshe zai buɗe hanyar fahimtar da amfani da abubuwan da suka shafi macroscopic da suka shafi fannoni daban-daban na bincike kamar kimiyyar lissafi, sunadarai da ilmin halitta.
A shekarar 2020, Jami'ar Kimiyya da Fasaha ta Huazhong ta gabatar da shawarar amfani da hanyar gani-gani don aunawa da sake gina bugun attosecond daidai ta hanyar fasahar gate mai haske da aka warware ta mita. A shekarar 2020, Kwalejin Kimiyya ta kasar Sin ta kuma bayar da rahoton cewa ta samu nasarar samar da bugun attosecond da aka ware ta hanyar tsara filin daukar hoto na femtosecond ta hanyar amfani da fasahar shiga ta hanyar amfani da fasahar shiga ta hanyar haske mai haske biyu. A shekarar 2023, wata kungiya daga Jami'ar Tsaro ta Kasa ta gabatar da wani tsari mai sauri na PROOF, wanda ake kira qPROF, don tantance bugun attosecond da aka ware mai fadi-fadi.
A shekarar 2025, masu bincike daga Kwalejin Kimiyya ta kasar Sin da ke Shanghai sun yi nazari kan yadda ake amfani da na'urarlaserfasahar daidaitawa bisa tsarin daidaitawar lokaci mai zaman kansa, wanda ke ba da damar auna jitter na lokaci mai inganci da kuma amsawar lasers na picosecond a ainihin lokaci. Wannan ba wai kawai yana sarrafa jitter na tsarin a cikin kewayon attosecond ba, har ma yana haɓaka amincintsarin lasera lokacin aiki na dogon lokaci. Tsarin bincike da sarrafawa da aka haɓaka zai iya yin gyara na ainihin lokaci don jitter na lokaci. A cikin wannan shekarar, masu bincike suna amfani da lasers na relativistic intensity spacetime vortices (STOV) don samar da bugun gamma-ray na attosecond wanda aka ware wanda ke ɗauke da motsi na kusurwar orbital angular.
Fannin laser na attosecond yana cikin wani lokaci mai sauri, wanda ya shafi fannoni da dama, tun daga bincike na asali zuwa haɓaka aikace-aikace. Ta hanyar ƙoƙarin ƙungiyoyin bincike na kimiyya, gina ababen more rayuwa, goyon bayan manufofin ƙasa, da haɗin gwiwa da musayar ra'ayi na cikin gida da na ƙasashen waje, tsarin da China ke bi a fannin laser na attosecond zai ji daɗin fa'idodin ci gaba. Yayin da ƙarin jami'o'i da cibiyoyin bincike suka shiga cikin binciken laser na attosecond, za a haɓaka ƙungiyar ƙwararrun masu bincike na kimiyya waɗanda ke da hangen nesa na duniya da ƙwarewar kirkire-kirkire, wanda ke haɓaka ci gaban kimiyya mai ɗorewa. Babban cibiyar kimiyya ta ƙasa Attosecond kuma za ta samar da babban dandamalin bincike ga al'ummar kimiyya kuma ta ba da gudummawa sosai ga ci gaban kimiyya da fasaha.
