Inqubekela phambili yakamuva ngendlela yesizukulwane se-laser kanye okushaUcwaningo lwe-Laser
Muva nje, iqembu elicwaningayo likaSolwazi Zhang Huaijin noProfessor Yu Hahahai we-State key Lantory of elestrust yunivesithi ye-Shendong University ye-Shandong University basebenza ndawonye ukuxazulula inkinga futhi bahlongoza ngendabuko I-ND: I-Yvo4 Laser Crystal njengento yokucwaninga okumele. Ukukhishwa kweLaser okuphezulu kwe-superfluescence kutholakala ngokuphuka umkhawulo we-Electron Energy Level, kanye nobudlelwano bomzimba phakathi kwesizukulwane se-laser nomkhawulo (Inombolo ye-Phonon ihlobene kakhulu) iyavela, futhi ifomu lokubonisa liyefana nomthetho kaCurie. Lolu cwaningo lushicilelwe ezokuxhumana ngemvelo (DOI: 10.1038 / S41467-023-433959-9) Ngaphansi kwegama elithi "Photon-Phonon ngokubambisana i-Laser". I-Yu FU ne-FUI LUGH, STEEN STUDIT ye-PHD ye-Class 2020, i-State Key Laboratory yezinto zokwakha ama-crystal, i-shaijin zhang, i-shandong zhang, ne-nanjing University, ne-Nanjing University, abalobi abahambisanayo.
Njengoba u-Einstein ahlongoza umbono wokukhanya wemisebe evuselelwa ngekhulu leminyaka elidlule, indlela ye-laser yathuthukiswa ngokuphelele, kwathi ngo-1960, iMaiman yasungulwa i-laser eyokuqala eqinile eqinile. Ngesikhathi sesizukulwane se-laser, ukuphumula okushisayo kuyinto ebalulekile yomzimba ehambisana ne-laser Generation, okuthinta kakhulu ukusebenza kwe-laser namandla ama-laser atholakalayo. Ukuphumula okushisayo kanye nomphumela we-thermal bekulokhu kubhekwa njengemingcele esemqoka engokomzimba enqubweni ye-laser, okumele incishiswe ngokudluliswa okuhlukahlukene kokushisa kanye nobuchwepheshe besiqandisi. Ngakho-ke, umlando wokuthuthuka kwe-laser uthathwa njengowumlando womzabalazo wokushisa udoti.
Ukubuka konke kwe-theoretical of Photon-Phonon Cooperative Pumpleng laser
Ithimba lokucwaninga selivele lihlanganyele eLaser nase-Nonlinear Optical Material Research, kwathi eminyakeni yamuva nje, inqubo yokuphumula eshisayo ibikaqondakali ngokujulile ngombono we-solic physics eqinile. Kususelwa kumqondo oyisisekelo wokuthi ukushisa (lokushisa) kufakwe emidlalweni ye-microcosmic, kubhekwa ukuthi ukuphumula okushisayo ngokwayo kuyinqubo ye-quantum yamazinga we-elektroni, futhi athole iziteshi ezintsha ze-elektroni ukukhiqiza i-wavelength entshai-laser. Ngokusekelwe kulokhu kucabanga, umgomo omusha we-elektroni-phonon counter ukupompa isizukulwane sokuphamba, futhi umthetho wokuguqulwa we-elektroni ngaphansi kokuhlangana kwe-electron-phonen utholakala ngokuthatha i-ND: yvo4 crystal, njengento emele. Ngasikhathi sinye, phonson-photon-phonon counter laser yokupompa yakhiwa, esebenzisa ubuchwepheshe be-Laser Diode yendabuko ye-Laser Diode. I-Laser ne-Rave Wavelength 1168NM ne-1176NM yakhelwe. Ngalesi sisekelo, ngokusekelwe kwisisekelo esiyisisekelo sesizukulwane se-laser kanye ne-elektroni-shon coupling, kutholakala ukuthi umkhiqizo wokugcina umkhawulo we-laser kanye nokushisa okufanayo, okufana nokubonisa umthetho oyisisekelo wezesikhundla elungiselelweni.
Ukuqashelwa kokuhlola kwe-Photon-Phonon Cooperativeukupompa i-laser
Lo msebenzi uhlinzeka ngombono omusha wokucwaninga okunqenqemeni kwe-Laser Generation Mechanism,I-Laser Physics, kanye ne-laser ephezulu yamandla, kukhombisa ubukhulu bokuklama okusha kweLaser Wavelength Technology kanye nokuhlolwa kweLaser Crystal, futhi kungaletha imibono emisha yocwaningo yokuthuthuka kweI-Quantum Optics, umuthi we-laser, ukubonisa kwe-laser kanye nezinye izinkambu zohlelo lokusebenza ezihlobene.
