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 pamwe chete kugadzirisa dambudziko uye vakaronga nzira yekugadzira laser ye phoon-phonon crystal, YVO, uye yakatora laser yechinyakare nzira mumiririri tsvakurudzo 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 Yunivhesiti yeNanjingpong, uye Cheng Hee. vanyori.
Sezvo Einstein akakurudzira yakasimudzwa dzidziso 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 neyakasiyana-siyana 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) kunowanikwa mune microcosmic phonons, inofungidzirwa kuti kuzorora kwekupisa pachayo inzira yehuwandu hwekubatanidza maelectron-phonon, iyo inogona kuona quantum kugadzirwa kwemazinga emagetsi emagetsi kuburikidza neakakodzera dhizaini yelaser, uye kuwana nzira nyowani dzekuchinja erekitironi kuti dzigadzire hutsva hutsva.laser. 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 wekutanga wekugadzirwa kwelaser uye electron-phonon coupling, zvinowanikwa kuti chigadzirwa chelaser chizvarwa chikumbaridzo uye tembiricha chinogara chiripo, chakafanana nekuratidzwa kwemutemo waCurie mune magineti, uye zvakare inoratidza iwo mutemo wekutanga wemuviri mune yakakanganisika chikamu shanduko 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.
