Inkqubela phambili yamva nje kwindlela yokuvelisa i-laser kunye nentshauphando lwelaser
Kungekudala, iqela lophando likaNjingalwazi uZhang Huaijin kunye noNjingalwazi uYu Haohai we-State Key Laboratory ye-Crystal Materials yeYunivesithi yaseShandong kunye noNjingalwazi u-Chen Yanfeng kunye noNjingalwazi u-He Cheng we-State Key Laboratory ye-Solid Microstructure Physics yeYunivesithi yaseNanjing baye basebenza kunye ukusombulula ingxaki kwaye bacebisa ukuba i-laser ivelise i-laser ye-phoon-phonon ye-colla ye-laser, kunye ne-laser ye-laser. into yophando olumele. Imveliso ye-laser esebenzayo ephezulu ye-superfluorescence ifunyanwa ngokuqhekeza umda wenqanaba lamandla e-electron, kunye nobudlelwane bomzimba phakathi kwe-laser generation threshold kunye nobushushu (inombolo yephonon inxulumene ngokusondeleyo) iyatyhilwa, kwaye ifom yentetho iyafana nomthetho kaCurie. Uphononongo lupapashwe kwiNdawo yoNxibelelwano lweNdalo (doi: 10.1038 / S41467-023-433959-9) phantsi kwegama elithi "Photon-phonon collaboratively pumped laser". U-Yu Fu noFei Liang, umfundi we-PhD weKlasi ye-2020, i-State Key Laboratory ye-Crystal Materials, iYunivesithi yaseShandong, ngababhali bokuqala, u-Cheng He, i-State Key Laboratory ye-Solid Microstructure Physics, iYunivesithi yaseNanjing, ungumbhali wesibini, kunye noNjingalwazi uYu Haohai kunye no-Huaijin Zhang, iYunivesithi yaseShandongpong, kunye neYunivesithi yaseNanjing, kunye neYunivesithi yaseNanjing ababhali.
Ukusukela oko u-Einstein ecebise ithiyori yokukhanya evuselelweyo kwinkulungwane edlulileyo, indlela yelaser iphuhliswe ngokupheleleyo, kwaye ngo-1960, uMaiman wayila i-laser yokuqala ye-optically pumped solid-state. Ngexesha lokwenziwa kwelaser, ukuphumla kwe-thermal yinto ebalulekileyo yomzimba ehamba nesizukulwana selaser, esichaphazela kakhulu ukusebenza kwelaser kunye namandla e-laser akhoyo. Ukuphumla kwe-thermal kunye nefuthe le-thermal lihlala lithathwa njengeyona nto iphambili yeparameters eyingozi kwinkqubo ye-laser, ekufuneka incitshiswe ngokutshintshwa kobushushu obuhlukeneyo kunye nobuchwepheshe befriji. Ngoko ke, imbali yophuhliso lwe-laser ithathwa njengembali yomzabalazo kunye nokushisa kwenkunkuma.
Isishwankathelo sethiyori ye-photon-phonon cooperative pumping laser
Iqela lophando kudala libandakanyeka kwi-laser kunye ne-nonlinear optical materials research, kwaye kwiminyaka yakutshanje, inkqubo yokuphumla kwe-thermal iye yaqondwa ngokunzulu kwimbono ye-fiziksi yombuso oqinileyo. Ngokusekwe kumbono osisiseko wokuba ubushushu (ubushushu) bufakwe kwiiphononi ze-microcosmic, kucingwa ukuba ukuphumla kwe-thermal ngokwayo kuyinkqubo ye-quantum yokudibanisa i-electron-phonon, enokuqonda ukulungelelaniswa kwe-quantum yamanqanaba ombane we-electron ngoyilo olufanelekileyo lwe-laser, kunye nokufumana amajelo amatsha okutshintsha i-electron ukuvelisa ubude obutsha.laser. Ngokusekelwe kule ngcinga, umgaqo omtsha we-electron-phonon cooperative pumping laser generation ucetywayo, kwaye umgaqo we-electron transition phantsi kwe-electron-phonon coupling uthathwe ngokuthatha i-Nd: YVO4, i-crystal ye-laser eyisiseko, njengento emele. Ngelo xesha, i-photon-phonon cooperative laser pumping engapheliyo yakhiwe, esebenzisa iteknoloji ye-laser diode pumping technology. I-Laser enobude obunqabileyo be-1168nm kunye ne-1176nm iyilwe. Ngesi siseko, ngokusekwe kumgaqo osisiseko wokuvelisa i-laser kunye ne-electron-phonon coupling, kufumaniseka ukuba imveliso ye-laser generation threshold kunye nobushushu buhlala buhleli, obufana nokubonakaliswa komthetho kaCurie kwimagnetism, kwaye ikwabonisa nomthetho osisiseko wenyama kwinkqubo yotshintsho lwesigaba esiphazamisekileyo.
Ukuzaliseka kovavanyo lwentsebenziswano ye-photon-phononukumpompa laser
Lo msebenzi ubonelela ngombono omtsha wophando olutsha kwindlela yokuvelisa i-laser,laser physics, kunye ne-laser yamandla aphezulu, ikhomba idimension entsha yoyilo lolwandiso lwetekhnoloji yolwandiso lwamaza e-laser kunye nokuhlola ikristale yelaser, kwaye inokuzisa izimvo ezintsha zophando kuphuhliso lwe.i-quantum optics, iyeza le-laser, ukubonisa i-laser kunye nezinye iindawo ezihambelanayo zesicelo.
