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 kaha teitei o te superfluorescence ka puta ma te pakaru i te rohe taumata hiko irahiko, ka kitea te hononga tinana i waenga i te paepae whakangao laser me te pāmahana (he tata te hono o te waea waea), a he rite te ahua o 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, Te Whare Taiwhanga Matua o nga Rawa Crystal, Te Whare Wananga o Shandong, he kaituhi tuatahi, ko Cheng He, Te Whare Taiwhanga Matua o te Hangarau Ahumahi Toka, Te Whare Wananga o Nanjing, te kaituhi tuarua, a ko 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 whakahekehia 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 pamahana) kei roto i nga microcosmic phonons, e kiia ana 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 na roto i te hoahoa taiaho tika, me te 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,taiaho ahupūngao, me te taiaho kaha teitei, e tohu ana i te ahua hoahoa hou mo te hangarau roha roangaru taiaho me te torotoro karaihe taiaho, a tera pea e kawe mai he whakaaro rangahau hou mo te whanaketanga oquantum optics, rongoa laser, whakaaturanga laser me etahi atu mara tono e pa ana.
