ʻO nā holomua hou i ka mīkini hana laser a me nā mea hounoiʻi laser
I kēia mau lā, ua hana pū ka hui noiʻi o Professor Zhang Huaijin a me Professor Yu Haohai o ka State Key Laboratory of Crystal Materials o ke Kulanui o Shandong a me Professor Chen Yanfeng a me Professor He Cheng o ka State Key Laboratory of Solid Microstructure Physics o ke Kulanui o Nanjing e hoʻoponopono i ka pilikia. pilikia a noi aku i ka mīkini hana hoʻomohala laser o ka phoon-phonon collaborative pumping, a lawe i ka Nd: YVO4 laser crystal ma ke ʻano he mea noiʻi ʻelele.Loaʻa ka kiʻekiʻe o ka laser hoʻopuka o superfluorescence ma ka uhaki ʻana i ka palena o ka ikehu electron, a ua hōʻike ʻia ka pilina kino ma waena o ka paepae hanauna laser a me ka mahana (pili pono ka helu phonon), a ua like ke ʻano hōʻike me ke kānāwai Curie.Ua paʻi ʻia ke aʻo ʻana ma Nature Communications (doi: 10.1038/ S41467-023-433959-9) ma lalo o ka inoa "Photon-phonon collaboratively pumped laser".ʻO Yu Fu lāua ʻo Fei Liang, haumāna PhD o ka Papa 2020, State Key Laboratory of Crystal Materials, Shandong University, nā mea kākau mua, ʻo Cheng He, State Key Laboratory of Solid Microstructure Physics, Nanjing University, ʻo ia ka lua o ka mea kākau, a ʻo Professors Yu ʻO Haohai lāua ʻo Huaijin Zhang, Shandong University, a me Yanfeng Chen, Nanjing University, nā mea kākau like.
Ma muli o ka manaʻo ʻana o Einstein i ke kumumanaʻo radiation hoʻoulu ʻia o ka mālamalama i ke kenekulia i hala, ua hoʻomohala piha ʻia ka mīkini laser, a i ka makahiki 1960, ua hoʻokumu ʻo Maiman i ka laser paʻa paʻa o ka optically pumped mua.I ka wā o ka hoʻoulu ʻana i ka laser, ʻo ka hoʻomaha wela he mea koʻikoʻi koʻikoʻi i ke kino e pili ana i ka hanauna laser, e hoʻopilikia nui i ka hana laser a me ka mana laser i loaʻa.ʻO ka hoʻomaha wela a me ka hopena wela ua noʻonoʻo mau ʻia ʻo ia nā ʻāpana kino kino nui i ke kaʻina laser, pono e hoʻemi ʻia e nā ʻenehana hoʻoili wela a me nā ʻenehana refrigeration.No laila, ua manaʻo ʻia ka mōʻaukala o ka hoʻomohala ʻana i ka laser ʻo ia ka mōʻaukala o ka hakakā ʻana me ka wela wela.

ʻO ka manaʻo manaʻo o ka photon-phonon cooperative pumping laser

Ua lōʻihi ka hana ʻana o ka hui noiʻi i ka noiʻi laser a me ka nonlinear optical material, a i nā makahiki i hala iho nei, ua hoʻomaopopo loa ʻia ke kaʻina hana hoʻomaha wela mai ka ʻike o ka physics state solid.Ma muli o ka manaʻo kumu i hoʻokomo ʻia ka wela (mahana) i loko o nā microcosmic phonons, ua manaʻo ʻia ʻo ka hoʻomaha hoʻomaha ʻana iho he kaʻina hana quantum o ka hoʻohui ʻana o ka electron-phonon, hiki ke hoʻomaopopo i ka hoʻopili ʻana i nā pae ikehu electron ma o ka hoʻolālā laser kūpono, a loaʻa. nā ala hoʻololi electron hou e hana i ka lōʻihi hawewe houlaser.Ma muli o kēia noʻonoʻo, ua manaʻo ʻia kahi kumu hou o ka hoʻokumu ʻana i ka uila uila uila-phonon cooperative pumping laser, a ua loaʻa ke kānāwai hoʻololi electron ma lalo o ka hoʻohui ʻana electron-phonon ma ka lawe ʻana iā Nd:YVO4, kahi aniani laser kumu, ma ke ʻano he mea ʻelele.I ka manawa like, ua kūkulu ʻia kahi laser hoʻoheheʻe ʻole ʻia o ka photon-phonon cooperative pumping laser, kahi e hoʻohana ai i ka ʻenehana laser diode pumping.Hoʻolālā ʻia ʻo Laser me 1168nm a me 1176nm.Ma keia kumu, ma muli o ke kumu kumu o ka laser hanauna a me ka electron-phonon hui 'ana, ua ike ia i ka huahana o ka laser hanauna paepae a me ka mahana mea he mau, i ka mea like me ka hoike ana o Curie i ke kanawai ma magnetism, a hoike no hoi. ke kānāwai kino maʻamau i ke kaʻina hoʻololi pae ʻino.

ʻO ka ʻike hoʻāʻo ʻana o ka hui photon-phononka paila ʻana i ka laser

Hāʻawi kēia hana i kahi hiʻohiʻona hou no ka noiʻi ʻoki ʻana i ka mīkini hana laser,physics laser, a me ka laser ikehu kiʻekiʻe, e kuhikuhi ana i kahi ana hoʻolālā hou no ka ʻenehana hoʻonui ʻana i ka lōʻihi hawewe laser a me ka ʻimi ʻana i nā aniani aniani, a hiki ke lawe mai i nā manaʻo noiʻi hou no ka hoʻomohala ʻana oquantum optics, lāʻau lapaʻau laser, hōʻike laser a me nā kahua noi pili ʻē aʻe.
