Fiber lasers nyob rau hauv lub tshav pob ntawm optical fiber kev sib txuas lus

CovFiber Laserhais txog lub laser uas siv lub ntiaj teb tsis tshua muaj doped iav fibers raws li qhov nruab nrab nce. Fiber lasers tuaj yeem tsim los ntawm fiber ntau amplifiers, thiab lawv txoj haujlwm ua haujlwm yog: siv lub tshuab nqus fiber ntau ntev ua piv txwv. Ib ntu ntawm fiber ntau doped nrog lub ntiaj teb tsis tshua muaj hlau ions yog muab tso rau ntawm ob daim iav nrog xaiv qhov kev xav. Lub twj tso kua mis teeb ua khub rau hauv cov fiber ntau los ntawm daim iav sab laug. Daim iav sab laug xa tag nrho cov twj tso kua mis lub teeb thiab qhia txog lub laser tag nrho, yog li siv lub teeb pom kev zoo thiab tiv thaiv lub teeb pom kev ntawm lub teeb ntawm resonating thiab ua rau lub teeb tsis ruaj khov. Txoj cai endoscope tso cai rau lub laser ib feem mus rau hauv thiaj li yuav tsim lub tswv yim ntawm laser beam thiab tau txais cov zis laser. Photons ntawm lub twj tso kua mis wavelength yog absorbed los ntawm qhov nruab nrab, tsim ion tooj inversion, thiab thaum kawg tsim stimuled emission nyob rau hauv lub doped fiber nruab nrab rau cov zis laser.

Cov yam ntxwv ntawm fiber ntau lasers: High coupling efficiency vim lub laser nruab nrab nws tus kheej yog lub waveguide nruab nrab. High conversion efficiency, tsawg pib thiab zoo tshav kub dissipation nyhuv; Nws muaj ntau yam kev sib koom tes, zoo dispersion thiab stability. Fiber lasers kuj tuaj yeem nkag siab tias yog qhov hloov pauv wavelength ua tau zoo, uas yog, hloov lub wavelength ntawm lub twj tso kua mis lub teeb rau hauv lub lasing wavelength ntawm doped tsawg lub ntiaj teb ions. Qhov no lasing wavelength yog precisely cov zis lub teeb wavelength ntawm lub fiber laser. Nws tsis yog tswj los ntawm lub twj tso kua mis wavelength thiab tsuas yog txiav txim los ntawm lub ntiaj teb tsis tshua muaj doping ntsiab nyob rau hauv cov khoom. Yog li ntawd, semiconductor lasers ntawm txawv luv wavelengths thiab siab zog sib haum mus rau lub absorption spectra ntawm tsawg ntiaj teb ions yuav siv tau raws li cov twj tso kua mis qhov chaw kom tau txais laser outputs ntawm txawv wavelengths.

Fiber laser classification: Muaj ntau hom fiber ntau lasers. Raws li qhov nce nruab nrab, lawv tuaj yeem raug cais raws li: lub ntiaj teb tsis tshua muaj doped fiber ntau lasers, nonlinear effect fiber lasers, ib leeg siv lead ua fiber ntau lasers, thiab yas fiber ntau lasers. Raws li cov qauv fiber ntau, lawv tuaj yeem muab faib ua: ib leeg-clad fiber ntau lasers thiab ob-clad fiber ntau lasers. Raws li cov khoom siv doped, lawv tuaj yeem muab faib ua ntau tshaj kaum hom xws li erbium, neodymium, praseodymium, thiab lwm yam. Raws li txoj kev siv, nws tuaj yeem raug cais raws li: fiber ntau optical kawg lub ntsej muag, micro prism sab optical coupling pumping, nplhaib siv, thiab lwm yam. "8" zoo li kab noj hniav lasers, thiab lwm yam. Raws li hom kev ua haujlwm, lawv tuaj yeem raug cais raws li: pulsed optical fiber thiab nruam laser, thiab lwm yam. Txoj kev loj hlob ntawm fiber ntau lasers yog accelerating.lasers muaj zog heev, Ultrashort mem tes lasers, thiabnqaim-linewidth tunable laserstab tom tshwm sim ib tom qab. Tom ntej no, fiber ntau lasers yuav txuas ntxiv txhim kho nyob rau hauv cov lus qhia ntawm cov zis ntau zog, zoo beam zoo, thiab siab dua pulse peaks.
