Kev nce qib tshiab hauv ntau - wavelength picosecond fiber ntau
Tsis ntev los no, pab neeg ntawm ZHUD JIAQI, ib tug kws tshawb fawb los ntawm qhov chaw Laser Laser thiab kev kawm ua haujlwm hauv MultiS- wavel syn pengthous picosecond fiber ntau.
Multi - wavelength lasers nrog synchronized rov qab cov ntawv thov nyob rau hauv Raman scation, kaw lus hluavtaws, thiab sib txawv ntau tiam neeg. Tam sim no, cov hau kev rau tsim ntau - wavel pulser thev naus laus zis thiab tsis muaj zog hloov kho tshuab. Hom kev siv tshuab xauv yog tsuas yog raws cov qauv realonant, thiab kev tsis sib haum ntawm cov kab noj hniav ntev ntawm lub wavelengths loj yog txwv rau theem ib nrab. Lub hom phiaj yoj pulse lub zog ncaj qha tsim los ntawm cov tsis muaj zog hloov kho thiab kho dua tshiab}}} doped fiber ntau yog qhov yuav tsum tau ua kom sov. Lub wavelengtengting ua haujlwm tsuas yog txwv rau lub emission spectrum ntau ntawm qhov tsawg ntawm lub ntiaj teb ions.
Raws li cov teeb meem cascaded Raman Fiberno AmpliDier nrog ib qho kev tshawb fawb muaj cov noob ua kom muaj kev kho kom tsis tu ncua Hauv kev sim, siv ib qho ntxiv {{6} hloov cov txiaj ntsig Raman scationing bultes nyob rau ntawm 1065 nm, 1121 nm, thiab 1178 nm, feem. Lub Raman Fiber Amplifier nrog ib leeg- cov kab tsuag tsis xav tau kev hloov pauv ntawm qhov rov ua dua. Siv qhov nce {{15} evered diode li lub twj tso kua mis, qhov kev rov ua dua tshiab {mHz txog 50 mhz (daim duab 2). Cov tshuab no muab txoj hauv kev tshiab los tsim cov synchronized multure} wavel mus ua cov khoom siv hluav taws xob zoo li cas, thiab kev pom zoo, thiab ntau lub zog hluav taws xob.
