Nyob rau hauv lub sijhawm niaj hnub no ntawm kev loj hlob sai ntawm laser kev siv tshuab, ua kom muaj kev lag luam zoo li kev lag luam thiab kev tshawb fawb ua tub rog ..
{{01.} Cov ntsiab lus thiab kev ua tau zoo sib txawv
Tau txais nruab nrab
Fiber ntau siv lub ntiaj teb tsis tshua muaj hluav taws xob zoo li muaj cov khoom siv roj teeb, thiab laser aycillation yog tsim nyob rau hauv lub teeb ci ntsa iab tau tsim nyob rau hauv lub teeb ci ntsa iab yog tsim nyob rau hauv lub teeb ci ntsa iab yog tsim nyob rau hauv lub teeb ci ntsa iab yog tsim nyob rau hauv lub teeb ci ntsa iab yog tsim nyob rau hauv lub teeb ci ntsa iab yog tsim nyob rau hauv lub teeb ci ntsa iab yog tsim nyob rau hauv lub teeb ci ntsa iab yog tsim nyob rau hauv lub teeb ci ntsa iab tau tsim muaj cov qauv fiber ntau muaj cov qauv sib xyaw thiab tsis tas yuav muaj ib qho nyuaj cua txias kaw lus . Qhov hloov kho kho qhov muag ua rau nws tau zoo dua hauv ntau qhov chaw ua tiav .
Ntawm lub plawv ntawm cov fiber ntau laser yog cov ntsuas hluav taws xob, cov plaub hau tsis sib xws nrog cov khoom siv tsis sib xws thiab tsis zoo li, cov muaj zog} Txawm li cas los xij, cov fiber ntau} Txawm li cas los xij, cov roj hmab} Txawm li cas los xij, cov fiber ntau} Txawm li cas los xij, cov fiber ntau} Txawm tsis muaj cov kev ua haujlwm ntawm cov khoom siv fiber ntau thiab, siv cov roj hmab uas tsis muaj zog ntxiv nrog rau cov fiber ntau cov ntsiab lus, xws li erbium lossis ytterbium . doping qhia txog lub zog laser, tso cai rau kev coj lub teeb xwb tab sis tseem ua rau nws {}}
Tau-xeev laser (SSL) yog nyob rau ntawm nws cov khoom txawv, thiab cov khoom siv hloov tshiab, thiab cov khoom siv kho qhov muag tau ua tiav (NECH) doped sab hauv nws (xws li nd³n (xws li nd³n) ua tiav cov haujlwm ua haujlwm hauv lub teeb ua si, yog li tsim kho qhov hluav taws xob kev ua haujlwm ntawm lub teeb ci, ua kom muaj zog txheej txheem ntawm cov duab cua sov monochromatic thiab tseeb tiag tiag liaser nqaj .
② Kev ua tau zoo thiab efficiency
Cov tshuaj lom neeg tau paub rau lawv cov hluav taws xob tshwj xeeb, ua tsaug rau cov khoom siv hluav taws xob tsawg, feem ntau ua tiav cov txiaj ntsig zoo tshaj plaws, ua tiav cov txiaj ntsig zoo tshaj 30%.
Cov khoom siv-lub xeev muaj feem ntau tsis tshua muaj txiaj ntsig ntawm lawv cov ntau dua nce teeb rau kev tso pa .
③ Beam Zoo: cuam tshuam ncaj qha rau cov txiaj ntsig ntawm lasers hauv cov ntawv thov precision hauv cov ntawv thov
Ib qho kev ua haujlwm ib-lasers muaj cov nqaj muaj txiaj ntsig zoo, cov cim los ntawm nruj tsom thiab minimal divergence {}}
Cov kab-lub xeev-lub sij hawm, thaum muaj peev xwm muab cov teeb pom kev zoo, feem ntau muaj cov nqaj muaj zog ntawm cov qib fiber ntau, tshwj xeeb tshaj yog cov qib siab dua.
Txawm hais tias lawv qis dua kev ua tau zoo thiab cov khoom siv hluav taws xob tsis muaj peev xwm ua tau kom muaj zog ntau ntxiv los ntawm kev txwv cov kev txwv tsis pub dhau cov kev txwv kom muaj zog thiab kub dissipation .
Rasit fiber ntau cov hmoov av muaj qhov ruaj khov .
Nws cov qauv fiber ntau yog cov kev hloov pauv ntawm ib puag ncig (yog li cov av noo, yog li lawv tau hloov kho qhov ruaj khov kho tshiab thiab hloov kho kom muaj kev hloov pauv ib puag ncig. {}}
Lub hauv paus ruaj khov ntawm lub xeev cov lasers tsis zoo, thiab kev hloov pauv hauv cov kev ib puag ncig tej zaum yuav muaj feem ntau rau lawv qhov kev ua tau zoo.
⑤ Thaum tshav kub kub ua tsis tau
Lasers Lasers muaj cov cua sov zoo tshaj plaws . nws tuaj yeem ua haujlwm rau lub sijhawm ntev thiab tuaj yeem tiv thaiv lub zog loj {}}
Cov khoom siv-lub xeev tau yooj yim rau cov teebmeem cua sov dissipate, thiab nquag nquag ua haujlwm kub, cuam tshuam rau kev ua tau zoo thiab lub neej ntawm laser.
Qhov loj thiab txij nkawm nqi fasters fiber ntau lasers yog kev cog lus heev thiab xav tau yuav luag tsis muaj kev txij nkawm .
Qhov me me ntawm cov fiber thiab qhov tsis muaj cov iav sab nraud uas muaj feem xyuam rau kev khiav dej num ua haujlwm vim tias lub fiber ntau ntxiv, txo qis kev pheej hmoo ntawm kev sib tsoo nthuav tawm .
Cov kev ua yeeb yam ntawm cov tsom iav hauv lub xeev yog qhov tseem ceeb rau kev tswj hwm lub zog ntawm lub zog, tab sis kuj yuav tsum muaj kev kho kom zoo dua qub lasers . Qhov xav tau rau cov tsom iav sab nraud thiab qhov hnyav ntxiv rau cov kev siv nrog kev siv tsawg {}}
2.} Daim Ntawv Thov
Fiber ntau Ci ntsa iab hauv lub teb kev lag luam txiav thiab ua kom muaj zog ntawm cov khoom siv thiab kev hloov kho kom zoo nkauj heev thiab kho kom zoo nkauj . tib lub sijhawm, lub siab kam rau ntawm fiber ntau ua hauj lwm ib puag ncig muaj ntau qhov chaw muaj kev sib tw ua haujlwm hauv cov teb no .
Cov khoom siv hluav taws xob-lub xeev muaj qhov tshwj xeeb hauv kev ua haujlwm zoo nkauj xws li cov khoom siv dav dav thiab cov khoom siv dav dav}}} High-precision vuam thiab lub teeb-meting 3D cov khoom siv uas tsis yog siv cov khoom siv me me uas tsis yog cov khoom siv me me vim lawv cov khoom siv hlau vim lawv lub siab luv luv (ultraviolet, tob ultraviolet), luv mem tes dav (picosecond dav (picosecond dav (femtosecond) thiab siab-lub zog-lub xeev kev tshawb fawb hauv thaj chaw ib puag ncig, tshuaj, tub rog thiab yog li ntawm {21}.
3.} kev ua lag luam
Kuv lub teb chaws nyob rau hauv tus txheej txheem ntawm kev hloov pauv thiab kev tsim kho ntawm kev tsim khoom los ntawm cov khoom lag luam qis {} Lub khw muag khoom siab} Yog li ntawd, kev ua lag luam muaj peev xwm ntawm cov lis haujlwm fiber ntau loj.
Cov qib ntawm cov qauv ntawm cov khoom lag luam uas muaj zog tsawg, thiab muaj ntau yam kev lag luam kev lag luam loj xws li cov khoom lag luam zoo nkauj tag nrho; Nyob rau hauv cov nqe lus ntawm nruab nrab-lub zog txuas ntxiv cov lasers, hauv tsev zoo tsis muaj qhov tsis zoo, cov nqi kom zoo dua, thiab kev sib tw ua lag luam yog sib npaug; Nyob rau hauv cov nqe lus ntawm high-power nruam fiber ntau lasers, cov hom hauv tsev tau ua tiav cov muag khoom ib nrab {}}
Raws li rau cov khoom khov kho, vim tias kev tsim kho lig nyob hauv Suav teb, tam sim no tsis muaj cov tuam txhab npe nrog cov khoom lag luam no ua lawv cov lag luam tseem ceeb, thiab lawv feem ntau yuav cov khoom lag luam txawv teb chaws .
Cov lis dej khov yog tsuas yog siv hauv thaj chaw macro vim yog cov khoom siv ua haujlwm ntawm cov khoom lag luam laser ntawm cov khoom ua nyob rau hauv millimeter ntau); cov lasers khoom siv tau dav hauv kev ua kom muaj micrometer los hais txog qhov loj me, thiab ntau lub zog ntawm cov neeg siv khoom lag luam thiab lub zog me me
Feem ntau, cov lasers khoom thiab cov lis dej num muaj cov khoom siv sib tw sib txawv, thaum cov hlau ua kom zoo nkauj vim tias cov khoom siv coj ncaj qha rau kev siv nyiaj ntau scenes nrog nyias hlau tuab los yog cov kev ua haujlwm siab thiab cov ntaub ntawv sib tw, thiab lwm yam ntawm cov ntaub ntawv hlau, lawv tau siv hauv cov scenes nrog siab cov kev xav tau precision thiab kuj tsis muaj peev xwm them tus nqi .
