Munguva pfupi yapfuura, boka rekutsvagisa raProfessor Zhang Huaijin naProfessor Yu Haohai veState Key Laboratory yeCrystal Materials yeShandong University naProfessor Chen Yanfeng naProfessor He Cheng veState Key Laboratory yeSolid Microstructure Physics yeNanjing University vakashanda pamwechete kugadzirisa dambudziko uye akakurudzira iyo laser chizvarwa meshini yephoon-phonon yekubatana kupomba, uye yakatora yechinyakare Nd: YVO4 laser crystal semumiriri wekutsvaga chinhu. Iyo yepamusoro inoshanda laser kubuda kwe superfluorescence inowanikwa nekutyora muganho wemagetsi emagetsi, uye hukama hwepanyama pakati peiyo laser chizvarwa chikumbaridzo uye tembiricha (nhamba yephonon ine hukama hwepedyo) inoburitswa, uye fomu rekutaura rakafanana nemutemo waCurie. Chidzidzo chakabudiswa mukati Nature Communications (doi:10.1038/ S41467-023-433959-9) pasi pezita rokuti "Photon-phonon collaboratively pumped laser". Yu Fu naFei Liang, mudzidzi wePhD weKirasi 2020, State Key Laboratory yeCrystal Materials, Shandong University, vanyori vekutanga, Cheng He, State Key Laboratory yeSolid Microstructure Physics, Nanjing University, ndiye munyori wechipiri, uye Mapurofesa Yu. Haohai naHuaijin Zhang, Shandong University, uye Yanfeng Chen, Nanjing University, vanyori vanowirirana.
Sezvo Einstein akakurudzira dzidziso yemwaranzi yechiedza muzana ramakore rapfuura, iyo laser michina yakagadziridzwa zvizere, uye muna 1960, Maiman akagadzira yekutanga optically pumped solid-state laser. Munguva yekugadzirwa kwelaser, kuzorora kwekupisa chinhu chakakosha chemuviri chinoperekedza chizvarwa chelaser, icho chinokanganisa zvakanyanya kushanda kwelaser uye iripo laser simba. Kuzorora kwekupisa uye mhedzisiro yekupisa kwagara ichionekwa seyakakosha inokuvadza yemuviri paramita mune laser process, iyo inofanirwa kuderedzwa neakasiyana kupisa kupisa uye firiji matekinoroji. Naizvozvo, nhoroondo yekuvandudzwa kwelaser inoonekwa senhoroondo yekurwa nekupisa kwemarara.

Theoretical overview ye photon-phonon cooperative pumping laser

Chikwata chekutsvagisa chakagara chiri kuita laser uye nonlinear optical materials research, uye mumakore achangopfuura, iyo yekuzorora yekuzorora yave ichinzwisiswa zvakadzama kubva pamaonero eiyo solid state fizikisi. Kubva pane zano rekutanga rekuti kupisa (tembiricha) yakamisikidzwa mune microcosmic phonons, inofungidzirwa kuti kuzorora kwekupisa pachayo inzira yehuwandu hwekubatanidza maelectron-phonon, iyo inogona kuona quantum kugadzirwa kwemazinga emagetsi emagetsi kuburikidza neakakodzera dhizaini, uye kuwana. matsva erekitironi ekuchinja nzira kugadzira hutsva hwewavelengthlaser. Zvichienderana nekufunga uku, musimboti mutsva we electron-phonon cooperative pumping laser generation inokurudzirwa, uye electron transition mutemo pasi pe electron-phonon coupling inotorwa nekutora Nd: YVO4, basic laser crystal, sechinhu chinomiririra. Panguva imwecheteyo, iyo isina kuvharwa photon-phonon cooperative pumping laser inovakwa, iyo inoshandisa yechinyakare laser diode kupomba tekinoroji. Laser ine isingawanzo wavelength 1168nm uye 1176nm yakagadzirwa. Pahwaro uhwu, zvichibva pamusimboti weiyo laser chizvarwa uye electron-phonon coupling, inowanikwa kuti chigadzirwa che laser chizvarwa chikumbaridzo uye tembiricha inoramba iripo, iyo yakafanana nekutaura kwemutemo waCurie mumagnetism, uye zvakare inoratidza. iwo mutemo wekutanga wemuviri mune kusagadzikana kwechikamu chekuchinja maitiro.

Kuzadzikiswa kwekuyedza kwephoton-phonon cooperativekupomba laser

Iri basa rinopa maonero matsva ekucheka-kumucheto kutsvagisa pane laser kugadzirwa michina,laser physics, uye yakakwira simba laser, inonongedza dhizaini nyowani yelaser wavelength yekuwedzera tekinoroji uye laser crystal yekuongorora, uye inogona kuunza mitsva yekutsvagisa mazano ekuvandudzaquantum optics, laser mushonga, laser kuratidza uye mamwe ane hukama mashandisirwo minda.
