Nā holomua hou i ka ʻōnaehana hana laser a me nā mea hounoiʻi laser
I kēia mau lā aku nei, ua hana pū ka hui noiʻi o Polopeka Zhang Huaijin lāua ʻo Polopeka Yu Haohai o ke Keʻena Hoʻokolohua Kī Mokuʻāina o nā Mea Crystal o ke Kulanui ʻo Shandong a me Polopeka Chen Yanfeng lāua ʻo Polopeka He Cheng o ke Keʻena Hoʻokolohua Kī Mokuʻāina o ka Physics Microstructure Solid o ke Kulanui ʻo Nanjing e hoʻoponopono i ka pilikia a ua hāpai i ka ʻano hana hana laser o ka pumping hui pū ʻana o phoon-phonon, a ua lawe i ka kristal laser Nd:YVO4 kuʻuna ma ke ʻano he mea noiʻi ʻelele. Loaʻa ka hopena laser kiʻekiʻe o ka superfluorescence ma ka uhaki ʻana i ka palena pae ikehu electron, a ua hōʻike ʻia ka pilina kino ma waena o ka paepae hana laser a me ka mahana (pili pono ka helu phonon), a ua like ke ʻano o ka hōʻike ʻana me ke kānāwai o 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, he haumāna PhD o ka Papa 2020, State Key Laboratory of Crystal Materials, ke Kulanui ʻo Shandong, nā mea kākau mua, ʻo Cheng He, State Key Laboratory of Solid Microstructure Physics, ke Kulanui ʻo Nanjing, ka mea kākau ʻelua, a ʻo Polopeka Yu Haohai lāua ʻo Huaijin Zhang, ke Kulanui ʻo Shandong, a me Yanfeng Chen, ke Kulanui ʻo Nanjing, nā mea kākau like.
Mai ka wā i hāpai ai ʻo Einstein i ke kumumanaʻo radiation stimulated o ka mālamalama i ke kenekulia i hala, ua hoʻomohala piha ʻia ke ʻano laser, a i ka makahiki 1960, ua hana ʻo Maiman i ka laser solid-state mua i hoʻopili ʻia e ka optically. I ka wā o ka hana laser, ʻo ka hoʻomaha wela he hanana kino koʻikoʻi e hele pū ana me ka hana laser, kahi e hoʻopilikia nui ai i ka hana laser a me ka mana laser i loaʻa. Ua manaʻo mau ʻia ka hoʻomaha wela a me ka hopena wela ʻo ia nā ʻano kino koʻikoʻi i ke kaʻina hana 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 o ka laser ʻo ia ka mōʻaukala o ka hakakā ʻana me ka wela ʻōpala.

ʻIke kumumanaʻo o ka laser pumping cooperative photon-phonon

Ua lōʻihi ka hana a ke kime noiʻi i ka noiʻi ʻana i nā mea laser a me nā mea optical nonlinear, a i nā makahiki i hala iho nei, ua hoʻomaopopo hohonu ʻia ke kaʻina hana hoʻomaha wela mai ka manaʻo o ka physics solid state. Ma muli o ka manaʻo kumu e hoʻokomo ʻia ka wela (mahana) i loko o nā phonons microcosmic, ua manaʻo ʻia ʻo ka hoʻomaha wela ponoʻī he kaʻina hana quantum o ka hoʻopili ʻana o ka electron-phonon, hiki ke hoʻokō i ka quantum tailoring o nā pae ikehu electron ma o ka hoʻolālā laser kūpono, a loaʻa nā kahawai hoʻololi electron hou e hana i ka nalu hou.laserMa muli o kēia manaʻo, ua hāpai ʻia kahi kumumanaʻo hou o ka hanauna laser pumping cooperative electron-phonon, a ua loaʻa ke kānāwai hoʻololi electron ma lalo o ka hoʻopili ʻana o electron-phonon ma ka lawe ʻana iā Nd:YVO4, kahi kristal laser kumu, ma ke ʻano he mea hōʻike. I ka manawa like, ua kūkulu ʻia kahi laser pumping cooperative photon-phonon uncooled, kahi e hoʻohana ai i ka ʻenehana pumping diode laser kuʻuna. Ua hoʻolālā ʻia ka laser me ka nalu kakaikahi 1168nm a me 1176nm. Ma kēia kumu, ma muli o ke kumumanaʻo kumu o ka hanauna laser a me ka hoʻopili ʻana o electron-phonon, ua ʻike ʻia ʻo ka huahana o ka paepae hanauna laser a me ka mahana he mau, ʻo ia ka mea like me ka hōʻike ʻana o ke kānāwai o Curie i ka magnetism, a hōʻike pū i ke kānāwai kino kumu i ke kaʻina hoʻololi pae maʻamau.

Hoʻokō hoʻokolohua o ka hui pū ʻana o ka photon-phononlaser pamu

Hāʻawi kēia hana i kahi kuanaʻike hou no ka noiʻi ʻoi loa ma ka ʻōnaehana hana laser,ke kālaikūlohea laser, a me ka laser ikehu kiʻekiʻe, kuhikuhi i kahi ana hoʻolālā hou no ka ʻenehana hoʻonui nalu laser a me ka ʻimi ʻana i ke aniani laser, a hiki ke lawe mai i nā manaʻo noiʻi hou no ka hoʻomohala ʻana onā ʻike maka kuantum, lāʻau lapaʻau laser, hōʻike laser a me nā kahua noi pili ʻē aʻe.
