Kua ahu whakamua te tīma Reiti Irahiko Koreutu o te Whare Wānanga Pūtaiao o Haina i roto i te rangahau i ngā reiti irahiko koreutu tino piripono. I runga i te Shanghai Soft X-ray Free Electron Laser Facility, kua manatokohia te tikanga hou o te reiti irahiko koreutu echo harmonic cascade i whakaarohia e Haina, ā, kua riro mai te irahiko piripono X-ray ngohengohe me te mahi tino pai. Nō nā tata nei, i whakaputaina ngā hua ki Optica i raro i te taitara Coherent and ultra-short soft X-ray pulses from echo-enabled harmonic cascade electronic lasers.
Ko te taiaho irahiko kore-X tētahi o ngā pūtake mārama matatau rawa atu o te ao. I tēnei wā, ko te nuinga o ngā taiaho irahiko kore-X o te ao e ahu mai ana i te tikanga tukunga ā-whaiaro (SASE), he tino teitei te kanapa o te SASE me te whānui o te pāoro poto-iti taumata femto me ētahi atu mahi tino pai, engari ko te wiri SASE i te haruru, te ōritetanga me te pumau o tana pāoro irahiko kāore i te teitei, ehara i te "taiaho" roopu hihi-X. Ko tētahi o ngā huarahi whanaketanga tino nui i roto i te mara o te taiaho irahiko kore-X o te ao ko te whakaputa i te irahiko X-X tino ōrite me te kounga taiaho tikanga, ā, ko te huarahi nui ko te whakamahi i te tikanga whakahaere taiaho irahiko kore-kākano o waho. Ko te irahiko o te taiaho irahiko kore-kākano o waho e whiwhi ana i ngā āhuatanga o te taiaho irahiko, ā, he āhuatanga tino pai pērā i te ōritetanga katoa, te whakahaere ā-wāhanga me te tukutahi tika me te taiaho papu o waho. Heoi, nā te herenga o te roangaru me te whānui o te pāoro o te taiaho irahiko kore-kākano, he iti te whānuitanga o te kapinga roangaru poto me te roangaru o te pāoro o te taiaho irahiko kore-kākano o waho. Hei whakawhānui ake i te kapinga o te roanga ngaru poto o te taiaho irahiko kore purapura o waho, kei te kaha te whakawhanake i ngā momo whakahaere taiaho irahiko kore utu hou pēnei i te whakaputa harmony whakaata i roto i te ao i ngā tau tata nei.
Ko te taiaho irahiko kore purapura o waho tētahi o ngā huarahi hangarau matua hei whakawhanake i te taiaho irahiko kore hua teitei i Haina. I tēnei wā, kua whakamahia e ngā taputapu taiaho irahiko kore hua teitei e whā i Haina te aratau whakahaere purapura o waho. I runga i te Shanghai Deep Ultraviolet Free Laser Facility me te Shanghai Soft X-ray Free Electron Laser Facility, kua tutuki i ngā kaipūtaiao te whakakaha rama taiaho irahiko kore momo whakaata tuatahi o te ao me te whakakaha rama taiaho irahiko kore momo whakaata ultraviolet tino nui tuatahi. Hei whakatairanga ake i te taiaho irahiko kore purapura o waho ki te roangaru poto, i whakaarohia motuhaketia e te rōpū rangahau he tikanga hou o te taiaho irahiko kore taurite katoa me te rerenga hāmoni whakaata, i tangohia e te taputapu Shanghai Soft X-ray Free Electronic Laser hei kaupapa taketake, ā, i oti te tukanga katoa mai i te manatoko matua ki te whakakaha rama i roto i te roopu hihi-X ngohengohe. E whakaatu ana ngā hua rangahau, ki te whakatauritea ki te tikanga whakahaere momo purapura o waho tuku iho, he tino pai ngā āhuatanga ā-tirotiro o tēnei tikanga, nā te whakamahi a ngā kairangahau i te whanaketanga motuhake o te hangarau tātaritanga pāwera hihi-X tino tere (https://doi.org/10.1016/j.fmre.2022.01.027), kua manatokohia anō te mahi pai o tēnei tikanga hou i roto i te whakahaere roa pāwera me te whakaputa pāwera tino tere. Mā ngā hua rangahau e tika ana ka whakaratohia he ara hangarau whaihua mō te whakaputa i ngā taiaho irahiko kore utu tino piripono i roto i te roopu subnanometer, ā, ka whakaratohia he taputapu rangahau pai mō ngā mara o ngā whatu kore-raina hihi-X me te matū ā-tinana tino tere.
He tino pai te mahi a te taiaho irahiko kore utu o te reima harmony echo: ko te ahua maui ko te aratau cascade tikanga, ā, ko te ahua matau ko te aratau cascade harmony echo.
Ka taea te whakatutuki i te whakatikatika roa o te pā o te hihi-X me te whakaputa pā tere rawa mā te rerenga hākoritanga orooro.
