Tsis ntev los no kev hloov kho hauv laser tiam thiab kev tshawb fawb tshiab

Tsis ntev los no kev hloov kho hauv laser tiam thiab tshiabKev Tshawb Fawb Laser
Tsis ntev los no, pab pawg tshawb fawb txog xibfwb Zhang Hu Hao Crystal ua tus sawv cev tus neeg tshawb xyuas khoom. Qhov siab ua tau zoo liner ntawm superfluorescence yog tau txais los ntawm kev sib tw hauv lub zog laser thiab kub thiab txias rau kev sib hais yog tib txoj cai. Txoj kev tshawb no tau luam tawm hauv kev sib txuas lus (DOI: 10.1038 / s41467-023-433333-433333-433333-433333-433333-433333-433333-433333 Yu Fu thiab FEIG, PHD tub ntxhais kawm ntawm chav kawm quystal, thiab cov xib hwb tseem ceeb,
Txij li thaum Einstein tau thov kom muaj hluav taws xob ntsuas qhov teeb pom kev ntawm lub sijhawm, thiab xyoo 1960, Maiman tau tsim kho dua tshiab, thiab xyoo 1960 Thaum lub sij hawm ua las voos, thermal so yog qhov kev ua haujlwm tseem ceeb ntawm lub cev ua lag luam, uas cuam tshuam rau laser thiab muaj laser fais fab. Thermal so thiab thermal effect yeej ib txwm tau txiav txim siab raws li tus yuam sij uas muaj teeb meem rau cov txheej txheem laser, uas yuav tsum raug txo los ntawm ntau qhov hloov cua sov thiab tub yees txias. Yog li ntawd, keeb kwm ntawm Laser kev txhim kho yog suav tias yog keeb kwm ntawm kev tawm tsam nrog cov khib nyiab.

Theoretical txheej txheem ntawm Photon-Phonon Sib Koom Tes Ua Laser Laser

Cov pab pawg tshawb fawb tau ua ntev koom nrog Laser cov txheej txheem kev tshawb fawb, thiab hauv cov txheej txheem tshiab, lub thermal so kom tob tob los ntawm kev pom ntawm lub xeev cov khoom noj muaj zog. Raws li cov tswv yim yooj yim uas kub (kub) tau pom tias hluav taws xob rov qab, thiab muab cov kev hloov hluav taws xob tsim nyog, thiab muab cov kev hloov hluav taws xob tsim nyoglaserCov. Raws li qhov kev xav no, lub hauv paus ntsiab lus tshiab ntawm electron-phonon confloting yog muab los ntawm kev coj ntawm electron Nyob rau tib lub sijhawm, ib lub phonon sib koom tes nqus plua plav laser yog tsim, uas siv cov tsoos laser diode tso tshuab. Laser nrog tsis tshua muaj wavelength 1168nm thiab 1176NM yog tsim. Ntawm lub hauv paus no, raws li lub ntsiab lus tseem ceeb ntawm lasercing ecolling, nws pom tias cov kev qhia ntawm kev cai lij choj, thiab tseem ua rau pom kev cai lij choj hauv theem kev hloov pauv.

Kev sim ua kom paub tseeb ntawm Photon-Phonon sib koom tesTso rau laser

Qhov haujlwm no muab kev pom zoo tshiab rau kev tshawb fawb-ntug ntawm Laser tiam Laser,laser physics, thiab muaj zog laser, cov ntsiab lus tawm qhov kev tsim qauv laser tshiab dua rau cov thev naus laus zis txhim kho, thiab tuaj yeem nqa cov tswv yim tshawb fawb tshiab rau kev txhim kho ntawmQuantum Optics, Cov tshuaj laser, laser tso tawm thiab lwm daim ntawv thov cuam tshuam nrog.
