Intuthuko yakamuva kumshini wokukhiqiza i-laser nokushaucwaningo lwe-laser
Muva nje, iqembu locwaningo likaSolwazi Zhang Huaijin kanye noProfessor Yu Haohai we-State Key Laboratory ye-Crystal Materials yase-Shandong University kanye noSolwazi Chen Yanfeng kanye noProfessor He Cheng we-State Key Laboratory ye-Solid Microstructure Physics yase-Nanjing University basebenze ndawonye ukuxazulula inkinga. inkinga futhi kwahlongozwa indlela yokukhiqiza i-laser yokumpompa ngokuhlanganyela kwe-phoon-phonon, futhi kwathatha ikristalu ye-laser yendabuko ye-Nd:YVO4 njengento emele ucwaningo. Ukukhishwa kwe-laser esebenza kahle kakhulu ye-superfluorescence kutholakala ngokweqa umkhawulo wezinga lamandla e-electron, futhi ubudlelwano bomzimba phakathi komkhawulo wokukhiqiza i-laser nezinga lokushisa (inombolo yephonon ihlobene eduze) kuyembulwa, futhi ifomu lenkulumo liyafana nomthetho kaCurie. Ucwaningo lushicilelwe kuNature Communications (doi:10.1038/ S41467-023-433959-9) ngaphansi kwegama elithi “Photon-phonon collaboratively pumped laser”. U-Yu Fu no-Fei Liang, umfundi we-PhD we-Class 2020, i-State Key Laboratory ye-Crystal Materials, i-Shandong University, bangababhali bokuqala, u-Cheng He, i-State Key Laboratory ye-Solid Microstructure Physics, i-Nanjing University, umbhali wesibili, kanye noSolwazi Yu. U-Haohai no-Huaijin Zhang, i-Shandong University, kanye ne-Yanfeng Chen, i-Nanjing University, bangababhali abahambisanayo.
Kusukela u-Einstein ahlongoze ithiyori yokukhanya evuselelwe nge-radiation ekhulwini leminyaka elidlule, umshini we-laser usuthuthukiswe ngokugcwele, kwathi ngo-1960, uMaiman wasungula i-laser yokuqala ye-solid-state edonsa amehlo. Ngesikhathi sokukhiqizwa kwe-laser, ukuphumula okushisayo kuyinto ebalulekile yomzimba ehambisana nokukhiqizwa kwe-laser, okuthinta kakhulu ukusebenza kwe-laser namandla atholakalayo e-laser. Ukuphumula okushisayo kanye nomthelela wokushisa bekulokhu kubhekwa njengemingcele eyingozi yomzimba enqubweni ye-laser, okumele yehliswe ngokudluliswa kokushisa okuhlukahlukene kanye nobuchwepheshe besiqandisi. Ngakho-ke, umlando wokuthuthukiswa kwe-laser uthathwa njengomlando womzabalazo nokushisa kwemfucuza.

Uhlolojikelele lwetiyori ye-photon-phonon cooperative pumping laser

Ithimba labacwaningi sekuyisikhathi eside lizibandakanyile ocwaningweni lwe-laser kanye ne-nonlinear optical materials, futhi eminyakeni yamuva nje, inqubo yokuphumula okushisayo iye yaqondwa ngokujulile ngokombono we-solid state physics. Ngokusekelwe embonweni oyisisekelo wokuthi ukushisa (izinga lokushisa) kufakwe kumaphononi amancane, kucatshangwa ukuthi ukuphumula okushisayo ngokwakho kuyinqubo ye-quantum yokuhlanganisa i-electron-phonon, engakwazi ukubona ukuthungwa kwe-quantum yamazinga we-electron amandla ngomklamo ofanele we-laser, futhi uthole. amashaneli amasha okushintsha ama-electron ukukhiqiza ubude beza obushalaser. Ngokusekelwe kulokhu kucabanga, kuhlongozwa umgomo omusha wokukhiqiza i-laser yokupompa i-electron-phonon cooperative, futhi umthetho wokushintsha i-electron ngaphansi kokuhlanganisa i-electron-phonon utholakala ngokuthatha i-Nd:YVO4, i-laser crystal eyisisekelo, njengento emele. Ngesikhathi esifanayo, i-photon-phonon cooperative pumping laser engasetshenziswanga iyakhiwa, esebenzisa ubuchwepheshe bokumpompa be-laser diode bendabuko. I-laser enobude obuyivelakancane obuyi-1168nm no-1176nm yakhiwe. Ngalesi sisekelo, ngokusekelwe esimisweni esiyisisekelo sokukhiqizwa kwe-laser kanye ne-electron-phonon coupling, kutholakala ukuthi umkhiqizo we-laser generation threshold kanye nezinga lokushisa lihlala likhona, elifana nokuvezwa komthetho kaCurie kumagnetism, futhi libonisa. umthetho wemvelo oyisisekelo kunqubo yenguquko yesigaba esiphazamisekile.

Ukwenziwa kokuhlolwa kwe-photon-phonon cooperativeukupompa laser

Lo msebenzi uhlinzeka ngombono omusha wocwaningo olusezingeni eliphezulu mayelana nendlela yokukhiqiza i-laser,i-laser physics, kanye ne-laser yamandla aphezulu, ikhomba ubukhulu bomklamo omusha wobuchwepheshe bokunwetshwa kwe-laser wavelength kanye nokuhlola kwekristalu ye-laser, futhi ingase ilethe imibono emisha yocwaningo ukuze kuthuthukiswei-quantum optics, umuthi we-laser, isibonisi se-laser nezinye izinkambu zesicelo ezihlobene.
