Kua ahu whakamua te roopu Laser irahiko kore utu o te Hainamana Academy of Sciences i roto i te rangahau o nga taiaho hiko kore utu.I runga i te Shanghai Soft X-ray Free Electron Laser Facility, ko te tikanga hou o te echo harmonic cascade free electron laser i whakaarohia e Haina kua pai te manatoko, a kua whiwhihia te whakamarumaru X-ray iraruke me nga mahi tino pai.I tata nei, I whakaputaina nga hua i roto i te Optica i raro i te taitara Coherent and ultra-poto ngawari X-ray pulses from echo-enabled harmonic cascade free electron lasers.
Ko te X-ray free electron laser ko tetahi o nga puna marama tino matatau o te ao.I tenei wa, ko te nuinga o nga taiaho irahiko koreutu X-ray o te ao e ahu mai ana i runga i te tikanga whakahiato mahorahora (SASE), he tino teitei te kanapa o te SASE me te taumata femto ultra-poto te whanui puihi poto me etahi atu mahi pai, engari ko te wiri SASE. na te ngangau, kaore i te teitei te hono me te pumau o tana pupuhi radiation, ehara i te roopu X-ray "taiaho".Ko tetahi o nga ahunga whanaketanga tino nui i roto i te mara o te taiaho irahiko kore utu o te ao ko te whakaputa i te radiation X-ray tino hono me te kounga taiaho tikanga, a ko te huarahi nui ko te whakamahi i te punaha whakahaere taiaho hiko korekore o waho.Ko te iraruke o te taiaho irahiko kore kakano o waho ka whakawhiwhia ki nga ahuatanga o te taiaho kakano, a he tino pai nga ahuatanga penei i te whakakotahitanga katoa, te whakahaere wahanga me te tukutahi tika me te taiaho papua o waho.Heoi, na te iti o te roangaru me te whanui o te puihi o te taiaho kakano, he iti te kapinga roangaru poto me te awhe whakatikatika o te roangaru o te taiaho hiko korekore o waho.Hei whakawhānui ake i te roangaru poto o te kakano taiaho irahiko korekore o waho, kei te kaha whakawhanakehia nga momo mahi taiaho hiko kore utu penei i te reanga haruru o te ao i nga tau tata nei.
Ko te taiaho irahiko kore he uri o waho ko tetahi o nga huarahi hangarau matua ki te whakawhanake taiaho irahiko kore utu nui i Haina.I tenei wa, ko nga taputapu taiaho hiko kore utu e wha i Haina kua whakamahi i te aratau mahi uri o waho.I runga i te Shanghai Deep Ultraviolet Free electron Laser Facility me te Shanghai Soft X-ray Free Electron Laser Facility, kua tutuki nga kaiputaiao te tuatahi o te ao echo type free electron electron laser amplification me te tuatahi o nga ultraviolet echo type free electron taiaho whakakaha whakakaha.Hei whakatairanga ake i te taiaho irahiko korekore o waho ki te roangaru poto, i whakaarohia e te roopu rangahau he tikanga hou o te taiaho irahiko korekore tino hono me te haruru oro, i tangohia e te Shanghai Soft X-ray Free electron Laser device as te kaupapa taketake, me te whakaoti i te katoa o te mahi mai i te manatoko maataapono ki te whakanui marama i roto i te roopu X-ray ngawari.Ko nga hua rangahau e whakaatu ana ka whakatauritea ki te momo momo kakano o waho e rere ana, he tino pai rawa atu nga ahuatanga o tenei miihini, na roto i te tangohanga a nga kairangahau o te whakawhanake motuhake o te hangarau whakamaaramatanga o te hiihi X-ray ultrafast (https://doi.org/10.1016). /j.fmre.2022.01.027), Ko te mahi pai ake o tenei tikanga hou i roto i te whakahaere i te roanga o te putere me te whakangao tere tere ka whakamanahia.Ko nga hua rangahau e tika ana he huarahi hangarau ka taea mo te whakangao i nga taiaho irahiko kore utu i roto i te roopu subnanometer, a ka whakaratohia he taputapu rangahau pai mo nga mara o te X-ray nonlinear optics me te ultrafast matū tinana.
Ko te echo harmonic cascade free electron laser he tino pai te mahi: ko te ahua maui ko te aratau cascade tikanga, a ko te ahua matau ko te echo harmonic cascade.
Ko te whakarereketanga o te roanga o te hiihi X-ray me te whakaputanga tere tere ka taea e te echo harmonic cascade
