Ntev npaum li cas Fiber Laser Ntev?

Feem ntau cov chaw hauv online hais tias fiber ntau lasers kav ntev li 100, 000 teev thaum CO2 lasers dhau 30, 000 teev. Qhov no tsis yog tseeb kiag li. Cov lej no hais txog tus nqi hu ua "lub sijhawm nruab nrab ntawm kev ua tsis tiav" (MTBF), uas tsis zoo ib yam rau txhua qhov fiber ntau lasers. Hauv kev muaj tiag, koj yuav pom cov lej sib txawv rau ntau hom fiber ntau lasers.
MTBF ntsuas qhov kev ntseeg siab ntawm lub laser los ntawm kev qhia tias pes tsawg teev lub laser yuav tsum ua haujlwm ua ntej qhov tsis ua tiav. Nws tau txais los ntawm kev sim ntau lub laser units, thiab tom qab ntawd faib tag nrho cov sijhawm ua haujlwm los ntawm tag nrho cov kev ua tsis tiav.
Nov yog yam koj yuav tsum paub yog tias koj lub laser kev ua tsis tiav ntawm ib lub sijhawm no:
● Lub neej thaum ntxov:Yog hais tias fiber ntau laser muaj fabrication yuam kev, nws yuav muaj tsis ua hauj lwm thaum ntxov. Koj yuav tsum xyuas kom meej tias koj muaj kev yuav khoom lav uas npog fabrication yuam kev kom lub laser tuaj yeem hloov tau yam tsis muaj nqi.
●Lub neej li qub:Thaum koj tau dhau thawj lub sijhawm tseem ceeb ntawm lub neej thaum ntxov, tus nqi MTBF muab koj lub tswv yim zoo ntawm koj lub laser txoj kev ua tsis tiav. Lub siab MTBF yog qhov kev lees paub zoo tias txhua yam yuav mus zoo, tab sis tsis yog qhov lav. Koj tuaj yeem npaj rau kev ua tsis tiav thaum lub neej ib txwm muaj nyob hauv ntau txoj hauv kev: muaj lub laser seem uas yooj yim, xauj lub laser thaum koj li raug kho, lossis muaj kev lav phib xaub ntev.
● Thaum kawg ntawm lub neej:Thaum fiber ntau lasers nyob ze lawv lub neej kawg, txoj hauv kev tsis ua haujlwm nce siab heev. Txawm li cas los xij, kev lag luam zoo laser feem ntau tuaj yeem ua haujlwm dhau los ntawm nws cov MTBF.

Yuav Ua Li Cas Lub Hwj Chim ntawm Fiber Laser Scale?

Fiber lasers 'muaj peev xwm mus teev nyob rau hauv lub hwj chim yog txwv los ntawm Brillouin thiab Raman scattering raws li zoo raws li lub luv luv ntawm lub lasers lawv tus kheej. Ntau yam khoom, suav nrog amplifiers, keyboards, thiab cov ntsiab lus logic, xav tau cov kev teeb tsa uas tsis yog-linear.

Muaj ob chav kawm ntawm cov teebmeem nonlinear hauv optical fibers. Thawj qhov yog coj los ntawm Kerr nyhuv, lossis qhov kev siv zog ntawm qhov nruab nrab qhov ntsuas qhov ntsuas. Qhov tshwm sim no tshwm sim raws li ib qho ntawm peb qhov teebmeem, nyob ntawm seb hom teeb liab tawm tswv yim: cross-theem kev hloov pauv (CPM), tus kheej-theem kev hloov pauv (SPM), lossis plaub-yoj sib xyaw (FWM).

Qhov thib ob nonlinear nyhuv tshwm sim thaum qhov chaw kho qhov muag hloov qee qhov ntawm nws lub zog mus rau qhov nruab nrab nonlinear ntawm inelastic scattering. Xws li inelastic scattering tuaj yeem ua rau muaj tshwm sim xws li stimulated Brillouin scattering (SBS) thiab stimulated Raman scattering (SRS).

Txhua daim ntawv ntawm kev ua kom muaj zog tawg tuaj yeem ua rau muaj txiaj ntsig zoo rau cov fiber ntau. Nyob rau hauv ob qho tib si txheej txheem, yog hais tias qhov teeb meem fais fab nce siab tshaj ib qho chaw pib, qhov kev siv ntawm dispersed lub teeb nce exponentially. Vim hais tias ntawm qhov sib piv loj zaus hloov thiab qhov dav nce bandwidth, Raman amplification yog qhov zoo dua. Qhov sib txawv tseem ceeb ntawm lawv yog tias nyob rau hauv Brillouin, lub optical yoj cuam tshuam nrog tsawg zaus acoustic phonons, whereas nyob rau hauv Raman, qhov taw qhia optical yoj cuam tshuam nrog high-frequency optical phonons. Lwm qhov kev sib txawv tseem ceeb yog tias SRS tuaj yeem tshwm sim hauv ob qho kev qhia thaum SBS tsuas yog tshwm sim nyob rau hauv kev coj rov qab hauv cov fibers optical.

Ntev npaum li cas Fiber Laser Txiav?

Qhov tob ntawm fiber ntau laser txiav yog nyob ntawm ntau yam, nrog rau lub zog ntawm lub laser, hom khoom raug txiav, lub kaum sab xis ntawm kev txiav, qhov zoo ntawm lub lens tsom, thiab qhov ceev ntawm lub laser txav. .
Feem ntau, Fiber lasers tuaj yeem txiav cov hlau mus txog ob peb centimeters tuab. Txawm li cas los xij, qhov tseeb qhov tob uas Fiber laser txiav tuaj yeem sib txawv raws li cov ntawv thov tshwj xeeb thiab cov xwm txheej ntawm cov txheej txheem laser txiav.

Lub Fiber Laser Ua Haujlwm li cas (Thiab Nws Cov Cheebtsam) yog dab tsi?

Lub teeb yog tsim nyob rau hauv Laser Diodes
Lub laser diode emitting lub teeb yuav tsum tau pumped rau hauv fiber ntau laserLaser diodes hloov hluav taws xob rau hauv photons-los yog lub teeb-mus rau hauv lub fiber-optic cable. Vim li no, lawv tseem hu ua "tswj qhov chaw"
Txhawm rau tsim lub teeb, diodes siv ob lub tshuab hluav taws xob sib txawv:
● Thawj tus raug them zoo, uas txhais tau hais tias nws xav tau ib qho hluav taws xob ntxiv.
● Qhov thib ob yog them tsis zoo, uas txhais tau hais tias nws muaj ib qho hluav taws xob ntxiv, lossis ib qho hluav taws xob dawb.

Pump Light yog coj hauv Fiber-Optic Cable
Nyob rau hauv qhov xwm txheej, lub teeb mus rau txhua qhov chaw. Txhawm rau kom pom lub teeb rau hauv ib qho kev taw qhia thiab tau txais lub teeb ci laser, fiber ntau-optic cables siv ob yam tseem ceeb: cov tub ntxhais fiber ntau thiab cladding.
● Lub hauv paus yog qhov chaw uas lub teeb mus. Nws yog ua los ntawm silica iav thiab tsuas yog ib feem ntawm cov cable uas suav nrog lub ntiaj teb tsis tshua muaj.
● Cov cladding yog cov khoom uas nyob ib puag ncig lub hauv paus. Thaum lub teeb hits lub cladding, nws bounces rov qab rau hauv lub hauv paus. Qhov no tshwm sim vim hais tias lub cladding muab tag nrho cov sab hauv xav txog.

Lub teeb yog Amplified nyob rau hauv Laser Cavity
Raws li lub teeb twj tso kua mis mus los ntawm fiber ntau-optic cable, nws thiaj li nkag mus rau hauv lub laser kab noj hniav - ib cheeb tsam me me ntawm cable uas tsuas yog lub teeb ntawm ib lub wavelength tshwj xeeb tsim. Cov kws kho mob lub cev hais tias cov fiber ntau yog "doped" hauv cheeb tsam no vim tias nws tau raug tov nrog cov khoom tsis tshua muaj hauv ntiaj teb.
Raws li hais los ntawm doped fiber cuam tshuam nrog lub teeb, lawv cov electrons nce mus rau qib siab zog. Thaum lawv poob rov qab rau lawv lub xeev yooj yim, lawv tso tawm lub zog hauv daim ntawv ntawm photons lossis lub teeb. Lub cev engineers xa mus rau cov phenomena xws li "electron excitation" thiab "electron so".

Lub teeb laser ntawm ib qho tshwj xeeb wavelength yog tsim
Lub wavelength uas ua los ntawm doped fiber ntau txawv raws li lub doping lub caij ntawm lub laser kab noj hniav. Qhov no yog ib qho tseem ceeb heev, vim hais tias sib txawv wavelengths yog siv rau kev siv sib txawv. Cov khoom siv doping tuaj yeem yog erbium, ytterbium, neodymium, thulium, thiab lwm yam. Ytterbium-doped fiber ntau lasers, piv txwv li, tsim lub wavelength ntawm 1064 nm thiab siv rau cov ntawv thov xws li laser npav thiab laser tu.

Lub Laser Beam yog zoo li tus thiab tso tawm
Photons uas tawm ntawm lub resonant kab noj hniav tsim ib tug laser beam uas yog heev zoo collimated (los yog ncaj) vim lub fiber lub teeb coj lub zog. Nyob rau hauv qhov tseeb, nws yog heev collimated rau feem ntau laser daim ntaub ntawv.
Txhawm rau muab cov kab teeb ci laser ib qho kev xav tau, cov khoom sib txawv tuaj yeem siv tau, xws li lo ntsiab muag thiab kab teeb nthuav dav. Piv txwv li, peb cov fiber ntau lasers tau nruab nrog 254 hli focal ntev lens rau laser daim ntaub ntawv uas khawb rau hauv cov khoom (piv txwv li, laser engraving thiab laser texturing). Qhov no yog vim lawv qhov ntev focal ntev tso cai rau peb tsom mus rau lub zog ntau dua mus rau thaj chaw kom muaj kev txhoj puab heev ntawm laser ablation.

Dab tsi yog Beam Zoo ntawm Fiber Lasers?

Ib qho fiber ntau laser beam zoo nyob ntawm ob lub zog ntawm intracavity distortions thiab qee yam ntawm tus qauv resonator. Qhov zoo tshaj plaws, cov cuab yeej yuav tsim qhov hu ua Gaussian beam, tab sis qhov tseeb beam zoo yog ib txwm tsis zoo tag nrho. Qhov kev qhia lej rau qhov zoo meej beam zoo yog M2=1. Lub teeb pom kev zoo laser tsom ntau lub zog rau hauv qhov chaw me me. Qee cov txheej txheem zoo li laser welding zam beam zoo meej kom lawv tsis ablate ntau cov khoom. Txawm li cas los xij, feem ntau (xws li laser engraving thiab tu) xav tau cov kab teeb zoo.
