Ko nga ahunga whakamua hou i roto i nga miihini whakangao laser me nga mea hourangahau taiaho
I tata nei, kua mahi tahi te roopu rangahau a Ahorangi Zhang Huaijin me Ahorangi Yu Haohai o te State Key Laboratory of Crystal Materials o te Whare Wananga o Shandong me Ahorangi Chen Yanfeng me Ahorangi He Cheng o te State Key Laboratory of Solid Microstructure Physics o te Whare Wananga o Nanjing ki te whakaoti i te raruraru me te whakaaro i te tikanga whakangao taiaho o te phoon-phonon mahi tahi, ka tango i te karaihe taiaho Nd:YVO4 tuku iho hei taonga rangahau.Ko te putanga taiaho tino pai o te superfluorescence ka puta ma te pakaru i te rohe taumata hiko hiko, ka whakaatuhia te hononga tinana i waenga i te paepae whakatipuranga taiaho me te pāmahana (he tata te hono o te waea waea), a he rite te ahua ki te ture a Curie.I whakaputaina te rangahau i roto i te Nature Communications (doi:10.1038/ S41467-023-433959-9) i raro i te ingoa "Photon-phonon collaboratively pumped laser".Ko Yu Fu raua ko Fei Liang, he akonga PhD o te Akomanga 2020, State Key Laboratory of Crystal Materials, Shandong University, he kaituhi tuatahi, Cheng He, State Key Laboratory of Solid Microstructure Physics, Nanjing University, te kaituhi tuarua, me Ahorangi Yu Ko Haohai me Huaijin Zhang, Te Whare Wananga o Shandong, me Yanfeng Chen, Te Whare Wananga o Nanjing, he kaituhi-kaituhi.
Mai i te wa i whakaarohia e Einstein te ariā iraruke whakahihiko o te marama i te rautau kua hipa, kua tino whakawhanakehia te miihini laser, a, i te tau 1960, i hangaia e Maiman te taiaho totoka-a-te-rangi tuatahi.I te wa o te whakatipuranga laser, ko te whakangā waiariki he ahuatanga tino nui e whai ana i te whakatipuranga laser, e tino pa ana ki te mahi taiaho me te mana taiaho e waatea ana.Ko te whakamaarama wera me te paanga o te waiariki kua kiia ko nga tawhā tino kino i roto i te mahi taiaho, me whakaheke e nga momo whakawhiti wera me nga hangarau whakamatao.Na reira, ko te hitori o te whanaketanga laser ka kiia ko te hitori o te pakanga ki te wera ururua.
Tirohanga ariā o te photon-phonon mahi tahi taiaho pamu
Kua roa te roopu rangahau e mahi ana ki te rangahau taiaho me te rangahau rauemi whatu kore, a, i nga tau tata nei, kua tino maarama te tikanga whakangao waiariki mai i te tirohanga o te ahupūngao o te whenua.I runga i te whakaaro taketake ko te wera (te pawera) kei roto i nga microcosmic phonons, ka whakaarohia ko te whakamaaramatanga waiariki ano he tukanga quantum o te hononga irahiko-phonon, e taea ai te whakarite i te rahinga o nga taumata hiko irahiko ma te hoahoa laser tika, ka whiwhi. nga hongere whakawhiti irahiko hou hei whakaputa i te roangaru houtaiaho.I runga i tenei whakaaro, ka whakaarohia he maataapono hou mo te whakangao taiaho hikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohikohiko, a, ko te ture whakawhiti irahiko i raro i te hononga irahiko-phonon ka puta mai ma te tango i te Nd:YVO4, he karaihe taiaho taketake, hei taonga tohu.I te wa ano, ka hangaia he taiaho whakapoipoi kore-kore, e whakamahi ana i te hangarau whakamaarama taiaho.Taiaho ki te roangaru onge 1168nm me 1176nm kua hoahoa.I runga i tenei kaupapa, i runga i te kaupapa taketake o te whakatipuranga taiaho me te hono irahiko-phonon, ka kitea ko te hua o te paepae whakatipuranga taiaho me te pāmahana he pumau tonu, he rite tonu ki te whakaaturanga o te ture a Curie i roto i te aukumetanga, me te whakaatu ano hoki. te ture tinana taketake i roto i te tukanga whakawhiti wahanga raruraru.
Te whakatinanatanga o te mahi tahi photon-phononte pupuhi laser
Ko tenei mahi he tirohanga hou mo te rangahau tapahi-mata mo te miihini whakangao laser,laser ahupūngao, me te taiaho kaha teitei, e tohu ana i te taha hoahoa hou mo te hangarau roha roangaru taiaho me te torotoro karaihe taiaho, a tera pea ka kawe mai he whakaaro rangahau hou mo te whanaketanga oquantum optics, rongoa laser, whakaaturanga laser me etahi atu mara tono e pa ana.
