Kev vuam yog ib txoj kev sib txuas ob lossis ntau dua cov hlau ua ke los ntawm kev siv cua sov. Feem ntau kev vuam yuav tsum ua kom cov khoom siv sov mus txog rau qhov chaw yaj kom cov hlau hauv paus yaj kom puv qhov sib txawv ntawm cov pob qij txha, tsim kom muaj kev sib txuas zoo. Kev vuam laser yog ib txoj kev sib txuas uas siv laser ua qhov chaw kub.
Piv txwv li, siv lub roj teeb fais fab plaub fab: lub hauv paus roj teeb txuas nrog laser los ntawm ntau qhov chaw. Thaum lub sijhawm vuam laser tag nrho, lub zog sib txuas ntawm cov khoom siv, kev ua haujlwm zoo, thiab qhov tsis zoo yog peb qhov teeb meem uas kev lag luam txhawj xeeb ntau dua. Lub zog sib txuas ntawm cov khoom siv tuaj yeem pom los ntawm qhov tob thiab dav ntawm metallographic nkag mus (cuam tshuam nrog lub teeb laser); qhov ua haujlwm zoo tshaj plaws yog cuam tshuam nrog lub peev xwm ua tiav ntawm lub teeb laser; qhov tsis zoo feem ntau yog cuam tshuam nrog kev xaiv lub teeb laser; yog li ntawd, tsab xov xwm no tham txog cov khoom siv feem ntau hauv khw. Kev sib piv yooj yim ntawm ntau lub teeb laser tau ua tiav, vam tias yuav pab cov neeg tsim khoom lag luam.
Vim tiaslaser vuamyog qhov tseem ceeb ntawm kev hloov pauv lub teeb mus rau cua sov, ntau qhov tseem ceeb uas koom nrog yog raws li nram no: qhov zoo ntawm lub teeb (BBP, M2, lub kaum sab xis sib txawv), lub zog ceev, lub cheeb ntawm lub hauv paus, daim ntawv faib hluav taws xob, lub taub hau vuam hloov kho tau, cov qhov rai txheej txheem thiab cov ntaub ntawv ua tau feem ntau yog siv los tshuaj xyuas thiab sib piv cov teeb pom kev zoo laser los ntawm cov kev taw qhia no.
Kev Sib Piv ntawm Laser Singlemode-Multimode
Ib hom ntau hom txhais:
Ib hom yog hais txog ib qho qauv faib tawm ntawm lub zog laser ntawm ob-dimensional dav hlau, thaum ntau hom yog hais txog qhov chaw faib tawm ntawm lub zog tsim los ntawm kev sib tshooj ntawm ntau hom kev faib tawm. Feem ntau, qhov loj ntawm lub beam zoo M2 factor tuaj yeem siv los txiav txim seb cov zis laser fiber yog ib hom lossis ntau hom: M2 tsawg dua 1.3 yog ib hom laser ntshiab, M2 ntawm 1.3 thiab 2.0 yog ib hom laser quasi-ib hom (ob peb hom), thiab M2 loj dua 2.0. Rau multimode lasers.

Raws li pom hauv daim duab: Daim duab b qhia txog kev faib zog ntawm ib hom yooj yim, thiab kev faib zog hauv txhua qhov kev taw qhia hla lub plawv ntawm lub voj voog yog nyob rau hauv daim ntawv ntawm Gaussian nkhaus. Daim duab a qhia txog kev faib zog ntau hom, uas yog kev faib zog qhov chaw tsim los ntawm kev sib tshooj ntawm ntau hom laser ib leeg. Qhov tshwm sim ntawm kev sib tshooj ntau hom yog ib qho nkhaus tiaj tus.
Cov lasers ib hom uas siv ntau: IPG YLR-2000-SM, SM yog lub npe luv ntawm Ib Hom. Cov kev xam siv collimated focus 150-250 los xam qhov loj ntawm qhov chaw tsom, lub zog ceev yog 2000W, thiab qhov ceev zog tsom siv rau kev sib piv.
Kev sib piv ntawm ib hom thiab ntau homlaser vuamcov teebmeem
Ib hom laser: lub plawv me me, lub zog ceev ceev, muaj peev xwm nkag mus tau zoo, thaj chaw me me uas raug cua sov, zoo ib yam li riam ntse, tshwj xeeb tshaj yog tsim rau kev vuam cov phaj nyias thiab kev vuam ceev ceev, thiab siv tau nrog galvanometers los ua cov khoom me me thiab cov khoom uas muaj kev cuam tshuam zoo (cov khoom uas muaj kev cuam tshuam zoo heev), raws li pom hauv daim duab saum toj no, ib hom laser muaj lub qhov tseem ceeb me dua thiab muaj cov pa hlau sab hauv siab tsawg, yog li nws feem ntau tsis muaj qhov tsis zoo xws li cov qhov hauv. Ntawm qhov ceev qis, qhov tsos yog ntxhib yam tsis muaj cua tiv thaiv. Ntawm qhov ceev siab, kev tiv thaiv ntxiv. Qhov zoo ntawm kev ua roj zoo, qhov ua tau zoo siab, cov welds du thiab tiaj tus, thiab qhov txiaj ntsig siab. Nws yog qhov tsim nyog rau kev vuam pawg thiab kev vuam nkag mus.
Laser ntau hom: Lub plawv loj, lub zog ceev me ntsis dua li ib hom laser, riam blunt, qhov loj dua, cov qauv hlau tuab dua, qhov tob me dua-rau-dav piv, thiab ntawm tib lub zog, qhov tob nkag mus yog 30% qis dua li ntawm ib hom laser, yog li nws tsim nyog rau kev siv Haum rau kev ua tiav vuam taub qab thiab kev ua tiav phaj tuab nrog cov sib dhos loj.
Composite-Ring Laser Contrast
Kev vuam sib xyaw: Lub teeb laser semiconductor nrog lub wavelength ntawm 915nm thiab lub teeb laser fiber nrog lub wavelength ntawm 1070nm tau muab tso ua ke hauv tib lub taub hau vuam. Ob lub teeb laser tau faib ua coaxially thiab cov dav hlau focal ntawm ob lub teeb laser tuaj yeem hloov kho tau yooj yim, yog li cov khoom muaj ob qho tib si semiconductorlaser vuammuaj peev xwm tom qab vuam. Cov nyhuv yog ci ntsa iab thiab muaj qhov tob ntawm fiberlaser vuam.
Cov khoom siv semiconductors feem ntau siv lub teeb loj ntawm ntau dua 400um, uas yog lub luag haujlwm tseem ceeb rau kev ua kom sov cov khoom siv, yaj qhov chaw ntawm cov khoom siv, thiab ua kom cov khoom siv nqus tau ntawm cov laser fiber ntau (cov khoom siv nqus tau ntawm laser nce ntxiv thaum qhov kub nce ntxiv)
Lub nplhaib laser: Ob lub fiber laser modules tso tawm lub teeb laser, uas yog kis mus rau qhov chaw ntawm cov khoom siv los ntawm cov khoom siv fiber ntau sib xyaw (lub nplhaib optical fiber hauv cylindrical optical fiber).
Ob lub teeb laser nrog lub qhov annular: lub nplhaib sab nraud yog lub luag haujlwm rau kev nthuav dav qhov qhib qhov tseem ceeb thiab yaj cov khoom, thiab lub nplhaib sab hauv laser yog lub luag haujlwm rau qhov tob nkag mus, ua rau muaj kev vuam spatter tsawg heev. Lub zog laser lub nplhaib sab hauv thiab sab nraud tuaj yeem sib phim tau yooj yim, thiab lub plawv txoj kab uas hla tuaj yeem sib phim tau yooj yim. Lub qhov rais txheej txheem muaj kev ywj pheej ntau dua li ntawm ib lub teeb laser.
Kev sib piv ntawm cov teebmeem sib xyaw ua ke-ncig vuam
Vim tias kev vuam sib xyaw yog kev sib xyaw ua ke ntawm kev vuam thermal conductivity semiconductor thiab fiber optic tob tob vuam, qhov nkag mus rau sab nraud yog qhov ntiav dua, cov qauv metallographic yog ntse dua thiab nyias dua; tib lub sijhawm, qhov tsos yog thermal conductivity, lub pas dej molten muaj qhov hloov pauv me me, ntau yam loj, thiab lub pas dej molten ruaj khov dua, cuam tshuam rau qhov zoo li du.
Vim tias lub nplhaib laser yog kev sib xyaw ua ke ntawm kev vuam tob thiab kev vuam tob, lub nplhaib sab nraud kuj tseem tuaj yeem tsim qhov tob tob, uas tuaj yeem nthuav qhov qhib qhov tseem ceeb. Lub zog tib yam muaj qhov tob tob dua thiab cov metallography tuab dua, tab sis tib lub sijhawm, qhov ruaj khov ntawm lub pas dej molten yog me ntsis tsawg dua Qhov kev hloov pauv ntawm cov khoom siv fiber ntau semiconductor yog me ntsis loj dua li ntawm kev vuam sib xyaw, thiab qhov roughness yog qhov loj heev.
