Ngā whanaketanga hou o te pūnaha whakaputa laser me ngā mea hourangahau taiaho
Nō nā tata nei, kua mahi tahi te rōpū rangahau a Ahorangi Zhang Huaijin rāua ko Ahorangi Yu Haohai o te Whare Wānanga o Shandong, me Ahorangi Chen Yanfeng rāua ko Ahorangi He Cheng o te Whare Wānanga o Nanjing, ki te whakaoti i te raruraru, ā, kua whakaarohia te tikanga whakaputa laser o te pupuhi tahi phoon-phonon, ā, kua tangohia te karaihe laser Nd:YVO4 tuku iho hei kaupapa rangahau mā te tangata. Ka whiwhihia te putanga laser tino pai o te superfluorescence mā te pakaru i te rohe taumata pūngao irahiko, ā, ka whakakitea te whanaungatanga ā-tinana i waenga i te paepae whakaputa laser me te pāmahana (he hononga tata te tau phonon), ā, he rite te āhua o te kīanga ki te ture a Curie. I whakaputaina te rangahau ki Nature Communications (doi:10.1038/ S41467-023-433959-9) i raro i te ingoa "Photon-phonon collaboratively pumped laser". Ko Yu Fu rāua ko Fei Liang, he tauira PhD o te Akomanga 2020, State Key Laboratory of Crystal Materials, Te Whare Wānanga o Shandong, ngā kaituhi tuatahi, ko Cheng He o State Key Laboratory of Solid Microstructure Physics, Te Whare Wānanga o Nanjing, te kaituhi tuarua, ā, ko Ahorangi Yu Haohai rāua ko Huaijin Zhang o Te Whare Wānanga o Shandong, me Yanfeng Chen o Te Whare Wānanga o Nanjing, ngā kaituhi hoa mahi.
Mai i te whakaaro o Einstein mō te ariā irahiko whakaohooho o te mārama i te rautau kua taha ake nei, kua tino whanakehia te tikanga taiaho, ā, i te tau 1960, i hangaia e Maiman te taiaho totoka tuatahi e pupuhihia ana e te whatu. I te wā e whakaputahia ana te taiaho, he āhuatanga ā-tinana nui te whakangā wera e haere tahi ana me te whakaputanga taiaho, e tino pā kino ana ki te mahi taiaho me te mana taiaho e wātea ana. Kua whakaarohia tonutia te whakangā wera me te pānga wera hei ngā tawhā ā-tinana kino matua i roto i te tukanga taiaho, me whakaiti e ngā hangarau whakawhiti wera me te whakamatao. Nō reira, ko te hītori o te whanaketanga taiaho e kiia ana ko te hītori o te pakanga ki te wera para.
Tirohanga ariā o te taiaho papu mahi tahi photon-phonon
Kua roa te rōpū rangahau e mahi ana i ngā rangahau rauemi whatu rēseri me te kore-raina, ā, i ngā tau tata nei, kua tino mārama te tukanga whakangā wera mai i te tirohanga a te ahupūngao āhua totoka. I runga i te ariā taketake ko te wera (pāmahana) kei roto i ngā phonon moroiti, e whakaarohia ana ko te whakangā wera tonu he tukanga kuantum o te hononga irahiko-phonon, ka taea te whakatutuki i te whakaritenga kuantum o ngā taumata pūngao irahiko mā te hoahoa rēseri tika, me te whiwhi i ngā hongere whakawhiti irahiko hou hei whakaputa i ngā roangaru hou.rēseriI runga i tēnei whakaaro, ka whakaarohia he mātāpono hou mō te whakaputanga taiaho pupuhi tahi irahiko-phonon, ā, ka ahu mai te ture whakawhiti irahiko i raro i te hononga irahiko-phonon mā te tango i te Nd:YVO4, he tioata taiaho taketake, hei mea tohu. I taua wā anō, ka hangaia he taiaho pupuhi tahi photon-phonon kāore i whakamataohia, e whakamahi ana i te hangarau pupuhi taiaho diode tuku iho. Ka hangaia te taiaho me te roanga ngaru onge 1168nm me te 1176nm. I runga i tēnei, i runga i te mātāpono taketake o te whakaputanga taiaho me te hononga irahiko-phonon, ka kitea ko te hua o te paepae whakaputa taiaho me te pāmahana he pūmau, he rite ki te whakaaturanga o te ture a Curie i roto i te aukumetanga, ā, e whakaatu ana hoki i te ture ā-tinana taketake i roto i te tukanga whakawhiti wāhanga koretake.
Te whakatinanatanga whakamātautau o te mahi tahi photon-phononte pūwero laser
Mā tēnei mahi ka whakaratohia he tirohanga hou mō ngā rangahau matatau mō te tikanga whakaputa taiaho,te ahupūngao taiaho, me te taiaho pūngao teitei, e tohu ana i tētahi taha hoahoa hou mō te hangarau whakawhānui roangaru taiaho me te tūhuratanga karaihe taiaho, ā, tera pea ka kawea mai he whakaaro rangahau hou mō te whanaketanga ongā whatu matū, rongoā taiaho, whakaaturanga taiaho me ētahi atu mara tono e pā ana.
