Ngā au hangarau me ngā whanaketanga ongā taiaho attosecondi Haina
I te tau 2013, i ripoatahia e te Institute of Physics, Chinese Academy of Sciences, ngā hua ine o te 160 hei pāoro attosecond motuhake. I hangaia ngā pāoro attosecond motuhake (IAP) o tēnei rōpū rangahau i runga i ngā harmonics teitei-whakarite i peia e ngā pāoro laser femtosecond iti-5 i whakauhia e te CEP, me te tere tukurua o te 1 kHz. I whakaahuahia ngā āhuatanga wā o ngā pāoro attosecond e te spectroscopy totoro attosecond. E whakaatu ana ngā hua ka taea e tēnei raina hihi te whakarato i ngā pāoro attosecond motuhake me te roanga pāoro o te 160 attoseconds me te roangaru pokapū o te 82eV. Kua tutuki i te rōpū ngā whanaketanga hou i roto i te whakaputa pūtake attosecond me te hangarau spectroscopy totoro attosecond. Ka whakatuwherahia hoki e ngā pūtake mārama ultraviolet tino nui me te taumira attosecond ngā mara tono hou mō te ahupūngao matū whakapoto. I te tau 2018, i ripoatahia hoki e te Institute of Physics, Chinese Academy of Sciences, tētahi mahere hanga mō tētahi taputapu kaiwhakamahi ine tere-whakatau-wā whakawhiti-mātauranga e whakakotahi ana i ngā pūtake mārama attosecond me ngā momo pito ine. Mā tēnei ka taea e ngā kairangahau te whakahaere i ngā inenga ngāwari o ngā tukanga tino tere i roto i te rauemi, mai i te attosecond ki te femtosecond, me te whai i te nekehanga me te taumira ā-wāhi. Ā, ka taea e ngā kairangahau te tūhura me te whakahaere i ngā hihiri hiko tino tere i roto i ngā ngota, ngā ngota, ngā mata me ngā rauemi totoka papatipu. Hei whakamutunga, mā tēnei ka whakawātea i te ara mō te mārama me te whakamahi i ngā āhuatanga makroskopi e tika ana e kapi ana i ngā kaupapa rangahau maha pēnei i te ahupūngao, te matū me te koiora.
I te tau 2020, i whakaarohia e te Whare Wānanga Pūtaiao me te Hangarau o Huazhong te whakamahinga o tētahi huarahi whatu-katoa hei ine tika me te hanga anō i ngā pāta attosecond mā te hangarau kuaha whatu whakatau-auau. I te tau 2020, i pūrongo anō te Chinese Academy of Sciences kua angitu tā rātou whakaputa i ngā pāta attosecond motuhake mā te hanga i te mara whakaahua hiko pāta femtosecond mā te whakamahi i te hangarau kuaha whakawhiti-mārama-rua. I te tau 2023, i whakaarohia e tētahi tīma mai i te National University of Defense Technology tētahi tukanga PROOF tere, e kiia nei ko qPROOF, hei whakaahua i ngā pāta attosecond motuhake ultra-whānui.
I te tau 2025, i whakawhanakehia e ngā kairangahau o te Chinese Academy of Sciences i Shanghairēserihangarau tukutahitanga e hangai ana ki tētahi pūnaha tukutahitanga wā motuhake, e āhei ai te ine i te wiri wā tino tika me te urupare wā-tūturu o ngā taiaho picosecond. Kāore i te whakahaere noa i te wiri wā o te pūnaha i roto i te awhe attosecond engari i whakarei ake hoki i te pono o tepūnaha taiahoi te wā e mahi ana mō te wā roa. Ka taea e te pūnaha tātari me te whakahaere kua whakawhanakehia te mahi i te whakatikatika wā-tūturu mō te wiri wā. I taua tau anō, i whakamahia hoki e ngā kairangahau ngā taiaho STOV (ngā awhiowhio ā-wāhi-kaha relativistic) hei whakaputa i ngā pāoro hihi gamma attosecond motuhake e mau ana i te nekehanga koki taha taha.
Kei roto te mara o ngā taiaho attosecond i tētahi wā whanaketanga tere, e kapi ana i ngā āhuatanga maha mai i te rangahau taketake ki te whakatairanga tono. Mā ngā mahi a ngā tīma rangahau pūtaiao, te hanganga o ngā hanganga, te tautoko i ngā kaupapa here ā-motu, me te mahi tahi me ngā whakawhitiwhiti ā-rohe me te ao, ka kitea e Haina ngā tūmanakohanga whanaketanga whānui i roto i te mara o ngā taiaho attosecond. I te mea ka nui ake ngā whare wānanga me ngā whare rangahau e uru atu ana ki te rangahau mō ngā taiaho attosecond, ka whakatipuhia he rōpū pūkenga rangahau pūtaiao me te tirohanga ā-ao me ngā āheinga auaha, e whakatairanga ana i te whanaketanga pumau o te pūtaiao attosecond. Ka whakaratohia hoki e te whare pūtaiao nui ā-Motu a Attosecond tētahi tūāpapa rangahau matua mō te hapori pūtaiao, ā, ka nui ake ngā takoha ki te whakatairanga i te pūtaiao me te hangarau.
