Kufambira mberi munguva pfupi yapfuura mukugadzira michina ye laser uye itsvatsvakurudzo yelaser
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 iri uye vakapa zano rekugadzira laser mechanism ye phoon-phonon collaborative pumping, uye vakatora kristaro ye laser yeNd:YVO4 sechinhu chinomiririra tsvakurudzo. Kubuda kwelaser inoshanda zvakanyanya kwe superfluorescence kunowanikwa nekupfuura nepakati pemuganhu wesimba rema electron, uye hukama hwepanyama pakati pechiyero chekugadzira laser netembiricha (nhamba yephonon ine hukama hwepedyo) hunoonekwa, uye chimiro chekutaura chakafanana nemutemo waCurie. Chidzidzo ichi chakaburitswa muNature Communications (doi:10.1038/ S41467-023-433959-9) pasi pezita rekuti "Photon-phonon collaboratively pumped laser". Yu Fu naFei Liang, mudzidzi wePhD weKirasi 2020, State Key Laboratory of Crystal Materials, Shandong University, ndivo vanyori vekutanga, Cheng He, State Key Laboratory of Solid Microstructure Physics, Nanjing University, ndiye munyori wechipiri, uye Mapurofesa Yu Haohai naHuaijin Zhang, Shandong University, naYanfeng Chen, Nanjing University, ndivo vanyori vanowirirana.
Kubva Einstein paakapa dzidziso yemwaranzi inokonzereswa nechiedza muzana remakore rapfuura, nzira ye laser yakagadzirwa zvizere, uye muna 1960, Maiman akagadzira laser yekutanga inopombwa nemaziso. Munguva yekugadzira laser, kuzorora kwekupisa chinhu chakakosha chemuviri chinoperekedza kugadzirwa kwe laser, icho chinokanganisa zvakanyanya mashandiro e laser uye simba re laser riripo. Kuzorodza kwekupisa uye mhedzisiro yekupisa zvagara zvichionekwa sezvinhu zvakakosha zvinokuvadza zvemuviri mukuita kwe laser, izvo zvinofanirwa kuderedzwa nehunyanzvi hwakasiyana-siyana hwekufambisa kupisa uye hwekuisa mufiriji. Nokudaro, nhoroondo yekuvandudzwa kwe laser inoonekwa senhoroondo yekurwisana nekupisa kwakarasika.

Ongororo yedzidziso ye photon-phonon cooperative pumping laser

Chikwata chekutsvagisa chave chichitora nguva refu chichiongorora zvinhu zve laser uye zvisiri zve optical, uye mumakore achangopfuura, maitiro ekuzorora kwekupisa ave achinzwisiswa zvakadzama kubva pamaonero efizikisi ye solid state. Zvichibva papfungwa huru yekuti kupisa (tembiricha) kuri muma microcosmic phonons, zvinofungidzirwa kuti kuzorora kwekupisa pachako inzira ye quantum yekubatanidza ma electron-phonon, iyo inogona kuita kuti quantum igadziriswe yemazinga esimba rema electron kuburikidza nekugadzirwa kwe laser kwakakodzera, uye kuwana nzira itsva dzekuchinja ma electron kuti dzigadzire wavelength itsva.laser. Zvichibva pakufunga uku, musimboti mutsva wekugadzirwa kwelaser yekubatana kwema electron-phonon unokurudzirwa, uye mutemo wekuchinja kwema electron pasi pekubatanidza ma electron-phonon unobva pakutora Nd:YVO4, kristaro yelaser yekutanga, sechinhu chinomiririra. Panguva imwe chete, laser yekubatana kwema photon-phonon isina kutonhodzwa inogadzirwa, iyo inoshandisa tekinoroji yekupomba yelaser diode yechinyakare. Laser ine wavelength isingawanzo 1168nm uye 1176nm yakagadzirwa. Pahwaro uhwu, zvichibva pamusimboti wekutanga wekugadzirwa kwema laser uye kubatana kwema electron-phonon, zvinowanikwa kuti chigadzirwa chemuganho wekugadzirwa kwema laser uye tembiricha chinoramba chiripo, icho chakafanana nekutaura kwemutemo waCurie mumagnetism, uye chinoratidzawo mutemo wekutanga wefizikisi mukuchinja kwechikamu chisina kurongeka.

Kuedza kwekushanda pamwe chete kwe photon-phononkupomba laser

Basa iri rinopa maonero matsva ekutsvagisa kwepamusoro-soro pamusoro penzira yekugadzira laser,fizikisi yelaser, uye laser ine simba rakawanda, inoratidza divi idzva rekugadzira tekinoroji yekuwedzera wavelength yelaser uye kuongorora kwekristaro yelaser, uye inogona kuunza mazano matsva ekutsvagisa ekuvandudzaquantum optics, mushonga we laser, laser display nedzimwe nzvimbo dzekushandisa dzakabatana.
