Intuthuko yakamuva endleleni yokwenza i-laser kanye nentshaucwaningo lwe-laser
Muva nje, iqembu locwaningo likaSolwazi Zhang Huaijin kanye noSolwazi Yu Haohai we-State Key Laboratory of Crystal Materials yaseShandong University kanye noSolwazi Chen Yanfeng kanye noSolwazi He Cheng we-State Key Laboratory of Solid Microstructure Physics yaseNanjing University basebenze ndawonye ukuxazulula inkinga futhi baphakamisa indlela yokukhiqiza i-laser yokupompa ngokubambisana kwe-phoon-phonon, futhi bathatha ikristalu ye-laser yendabuko ye-Nd:YVO4 njengento emele ucwaningo. Ukukhishwa kwe-laser esebenza kahle kakhulu kwe-superfluorescence kutholakala ngokudlula umkhawulo wamandla e-electron, futhi ubudlelwano obungokoqobo phakathi komkhawulo wokukhiqiza i-laser kanye nokushisa (inombolo ye-phonon ihlobene eduze) buyavezwa, futhi ifomu lokuveza lifana nomthetho kaCurie. Ucwaningo lushicilelwe ku-Nature Communications (doi:10.1038/ S41467-023-433959-9) ngaphansi kwegama elithi “i-Photon-phonon collaboratively pumped laser”. UYu Fu noFei Liang, umfundi we-PhD ekilasini lika-2020, i-State Key Laboratory of Crystal Materials, eShandong University, bangababhali bokuqala, uCheng He, i-State Key Laboratory of Solid Microstructure Physics, eNanjing University, ungumbhali wesibili, kanti oSolwazi uYu Haohai noHuaijin Zhang, eShandong University, noYanfeng Chen, eNanjing University, bangababhali abahambisanayo.
Kusukela u-Einstein aphakamisa inkolelo-mbono yokukhanya evuselelwe ngemisebe yokukhanya ekhulwini leminyaka elidlule, indlela ye-laser isithuthukisiwe ngokuphelele, kwathi ngo-1960, uMaiman wasungula i-laser yokuqala yesimo esiqinile epompelwe ngokubona. Ngesikhathi sokukhiqizwa kwe-laser, ukuphumula kokushisa kuyinto ebalulekile engokwenyama ehambisana nokukhiqizwa kwe-laser, ethinta kakhulu ukusebenza kwe-laser kanye namandla e-laser atholakalayo. Ukuphumula kokushisa kanye nomphumela wokushisa bekulokhu kubhekwa njengemingcele ebalulekile eyingozi engokwenyama enqubweni ye-laser, okumele incishiswe ubuchwepheshe obuhlukahlukene bokudlulisa ukushisa kanye nokushisa. Ngakho-ke, umlando wokuthuthukiswa kwe-laser ubhekwa njengomlando wokulwa nokushisa okulahliwe.

Ukubuka konke kwethiyori kwe-laser yokupompa ngokubambisana ye-photon-phonon

Ithimba locwaningo selilokhu lihilelekile ocwaningweni lwezinto ezibonakalayo ze-laser kanye ne-nonlinear, futhi eminyakeni yamuva nje, inqubo yokuphumula kokushisa iqondwe ngokujulile ngokombono we-solid state physics. Ngokusekelwe emcabangweni oyisisekelo wokuthi ukushisa (izinga lokushisa) kufakwe kuma-phononi amancane, kubhekwa ukuthi ukuphumula kokushisa ngokwako kuyinqubo ye-quantum yokuxhumanisa i-electron-phonon, engafeza ukulungiswa kwe-quantum kwamazinga wamandla e-electron ngokuklama kwe-laser okufanele, futhi ithole iziteshi ezintsha zokuguqula i-electron ukuze ikhiqize ubude obusha be-wavelength.i-laser. Ngokusekelwe kulokhu kucabanga, kuphakanyiswa isimiso esisha sokukhiqizwa kwe-laser yokupompa ngokubambisana kwe-electron-phonon, futhi umthetho wokuguquka kwe-electron ngaphansi kokuhlanganiswa kwe-electron-phonon utholakala ngokuthatha i-Nd:YVO4, ikristalu ye-laser eyisisekelo, njengento emele. Ngesikhathi esifanayo, kwakhiwa i-laser yokupompa ngokubambisana ye-photon-phonon engapholi, esebenzisa ubuchwepheshe bendabuko bokupompa i-laser diode. I-Laser enobude obungavamile obungu-1168nm no-1176nm yaklanywa. Ngalesi sisekelo, ngokusekelwe esimisweni esiyisisekelo sokukhiqizwa kwe-laser kanye nokuhlanganiswa kwe-electron-phonon, kutholakala ukuthi umkhiqizo womkhawulo kanye nokushisa kwe-laser kuyinto engaguquki, efana nokubonakaliswa komthetho kaCurie kumagnetism, futhi ikhombisa nomthetho oyisisekelo wezinto eziphilayo enqubweni yokuguqulwa kwesigaba esingahlelekile.

Ukuqashelwa kokuhlola kokubambisana kwe-photon-phononi-laser yokupompa

Lo msebenzi unikeza umbono omusha wocwaningo olusezingeni eliphezulu mayelana nendlela yokukhiqiza i-laser,ifiziksi ye-laser, kanye ne-laser enamandla aphezulu, ikhomba ubukhulu obusha bomklamo wobuchwepheshe bokukhulisa ubude be-laser kanye nokuhlola ikristalu ye-laser, futhi ingaletha imibono emisha yocwaningo yokuthuthukiswa kwei-quantum optics, umuthi we-laser, isibonisi se-laser kanye nezinye izinkambu zohlelo lokusebenza ezihlobene.
