Lub Adjustable Spot DOE Laser Module puas siv tau hauv Laser Vuam?

DOE Laser Moduletsim lub zog-kho qhov taw tes-ntiv nplhaib me ntsis uas tuaj yeem siv rau laser vuam. Tab sis yuav siv nws li cas? Cia peb kawm paub ua ke!

Lub laser vuam ceev tuaj yeem hloov kho los ntawm kev siv lub ntsiab lus Gaussian nplhaib laser zog faib, thiab lub nplhaib taw tes laser vuam nyhuv tuaj yeem ua tiav los ntawm kev kho qhov taw tes nplhaib qhov chaw lub zog txheej txheem, txhawm rau txhim kho vuam ceev thiab cov nyhuv. Nov yog lub tswv yim tshiab thiab yooj yim raws li laser diffraction kom paub txog qhov taw tes nplhaib qhov chaw shaping ntawm cov qauv fiber ntau lasers. Gaussian nplhaib laser shaping txoj kev raws li DOE muaj tsuas yog ob lub DOE lo ntsiab muag. Nws yog ib qho yooj yim mus use thiab muaj peev xwm tswj tau lub zog piv ntawm cov ntsiab lus thiab lub nplhaib lub teeb me ntsis los pab cov neeg siv ceev nrooj nrhiav qhov zoo tshaj plaws vuam nyhuv. Lub module tuaj yeem hloov tau ntawm 100 feem pua ​​​​lub zog ntawm qhov chaw nruab nrab thiab tsis muaj zog ntawm qhov chaw nruab nrab, tuaj yeem ua haujlwm nrog ib hom thiab ntau hom lasers, yog qhov sib zog heev (tsawg dua 20 hli ntev), thiab muaj lub siab Laser- induced puas threshold (LDT) ntawm passive diffractive ntsiab. Lub tswv yim no zam qhov kev xav tau tshwj xeeb Gaussian nplhaib laser fiber ntau laser thiab ua rau kev tsim ntawm lub taub hau welded laser ntau yooj yim.

Laser vuam yog ib qho cuab yeej siv dav hauv ntau cov txheej txheem kev lag luam hauv tsheb, nkoj tsim, roj teeb pob, thiab lwm yam lag luam, uas vuam ceev dhau los ua ib qho ntawm cov txheej txheem tseem ceeb tshaj plaws txwv tsis pub muaj ntau yam kev siv laser vuam. Lub laser vuam ceev yuav raug txwv los ntawm ntau lub cev tshwm sim thaum lub vuam txheej txheem, xws li spatter, hump, thiab nce porosity ntawm vuam. Kev txwv rau cov txheej txheem vuam no tuaj yeem txo qis heev thaum siv lub nplhaib laser vuam txoj kev. Rau cov txheej txheem sib txawv ntawm cov khoom siv vuam (xws li hlau thickness, hlau hom, thiab geometry), taw tes-ntiv nplhaib laser vuam yuav tsum tau sib txawv adjustable point-ring zog ratios nyob rau hauv thiaj li yuav muab cov txheej txheem zoo tshaj plaws nyob rau hauv high welding speeds. Yog li ntawd, rau ntau lub tshuab kho qhov muag, kev tswj hwm, kho tau beam fais fab kev daws teeb meem yog qhov zoo sib piv.

Raws li pom nyob rau hauv daim duab 1, nyob rau hauv no taw tes-ring qhov chaw shaping tswvyim, peb tus txheeb ze txoj hauj lwm (a, b, thiab c) ntawm ob DOE yog qhia upward: tus txheeb ze tig kaum sab xis ntawm ob DOE yog 0, 7.5, thiab 15 degrees feem. Lub hauv qab qhia tau hais tias qhov kev siv zog sib txuas nrog txhua qhov kev taw qhia ntawm kev sib hloov nyob rau hauv qhov siab: (d) nyob rau hauv uas txhua lub zog yog concentrated ntawm qhov chaw taw tes, (f) uas txhua lub zog yog concentrated ntawm lub nplhaib, thaum (e) yog qhov chaw. qhov twg ib qho adjustable taw tes nplhaib lub zog yog faib proportionally, nrog ib co ntawm lub zog yog ib feem ntawm qhov chaw taw tes thiab ib feem ntawm lub nplhaib ib ncig.

Nyob rau hauv Gaussian nplhaib laser shaping, raws li lub tswv yim ntawm adjustable taw tes nplhaib qhov chaw zog piv ntawm fiber ntau, ntau txoj kev ntawm taw tes nplhaib chaw shaping yog siv ib tug tshwj xeeb multi-mode fiber ntau laser, uas muaj ob los yog peb core, qhov chaw. core yog ib puag ncig los ntawm ib lossis ob lub nplhaib sib dhos, thiab txhua tus tub ntxhais tuaj yeem teeb tsa nws lub zog laser cais. Yog li, lub zog ntawm lub hauv paus teeb pom kev zoo thiab lub nplhaib ncig lub teeb pom kev tuaj yeem hloov kho. Piv nrog rau ntau hom high-power fiber lasers, qhov no laser system muaj ntau dua complexity thiab nqi. Qhov thib ob, lub siab Numerical Aperture (NA) ntawm xws li Gaussian nplhaib laser-zoo li tus fiber ntau txhais tau hais tias yuav tsum muaj ib qho tshwj xeeb collimator, feem ntau xav tau ib qho khoom siv kho qhov muag loj dua li tus qauv welded optical feem ntawm fiber ntau lasers tam sim no siv. Thaum kawg, feem ntau muaj kev txwv rau qhov sib piv ntawm qhov nruab nrab thiab lub voj voog. Hauv qhov taw tes-ntiv nplhaib laser vuam, txhawm rau kom tau txais lub zog ntau dua ntawm kev sib koom ua ke, nws yog qhov tsim nyog los ua kom lub zog hauv lub nplhaib. Feem ntau ntawm lub zog nkag mus rau hauv qhov chaw nruab nrab thiab tsuas yog ib feem me me nkag mus rau hauv lub nplhaib, yog li tag nrho lub zog laser tsis tuaj yeem siv rau qhov no tshwj tsis yog siv cov kev cai fiber ntau.

Daim duab no piav qhia txog lwm txoj hauv kev ntawm qhov taw tes-ntiv nplhaib raws li fiber ntau Gaussian nplhaib laser shaping, uas ua tiav cov ntsiab lus-ntiv nplhaib laser vuam nyhuv, ua kom tiav lub zog piv hloov, thiab tseem yog ib qho yooj yim, kev lag luam, thiab kev kho qhov muag ncaj qha. Raws li diffractive optics, txoj kev no tau muab cov kev daws teeb meem zoo rau qhov system qhov chaw loj ntawm ntau-kilowatt fiber ntau laser system thiab kov yeej qhov tsis zoo ntawm kev ntxiv lwm cov khoom rau qhov kho qhov muag.

Lub diffraction shaping scheme muaj ob qhov sib txawv diffraction ntsiab DOE, tseem hu ua phaj phaj, muab tso rau ntawm tib lub qhov muag axis. Los ntawm kev tig ib theem phaj mus rau lwm qhov, lub sijhawm ncua ntawm lub nplhaib thiab qhov chaw nruab nrab tuaj yeem tau txais. Thaum cov kev sib hloov ntawm theem phaj yog xoom thiab nruab nrab ntawm tag nrho cov ntu, tag nrho cov theem sib tshooj nyob rau hauv ib feem, raws li qhia nyob rau hauv daim duab 1b, uas ua rau ib feem ntawm lub zog nkag mus rau lub nplhaib, thaum lub sij hawm seem ntawm lub zog nkag mus rau hauv nruab nrab point, qhov kev faib ua feem ntawm uas tuaj yeem hloov kho tsis tu ncua.

Tag nrho cov kev ua tau zoo ntawm lub zog hloov ntawm qhov chaw taw tes-ntiv nplhaib sib txawv ntawm 100 feem pua ​​​​rau ib qho chaw nruab nrab rau 80 feem pua ​​​​rau ib lub nplhaib. Kev ua tau zoo yog ploj mus rau qhov kev sib kis ntau dua thiab zoo li lub nplhaib thib ob ntawm cov ces kaum siab dua. Tag nrho cov kev hloov pauv tshwm sim ntawm ib lub kaum sab xis, sib npaug rau ib lub kaum sab xis. Lub zog hloov pauv ntawm qhov chaw nruab nrab yog qhia hauv daim duab 2, uas muaj kev sib raug zoo nrog lub kaum sab xis.

Qhov kev ua kom zoo ntawm qhov taw tes-ntiv nplhaib qhov chaw lub zog yog qhov tseem ceeb heev hauv point-ring laser vuam. Thaum cov txheej txheem tsis raug txiav txim siab, qhov hloov kho toroidal thiab point-shaped modules tuaj yeem hloov tau los ntawm ib qho passive DOE, uas nws tus kheej toroidal rau point-shaped power ratio yog suav tias yog qhov kev xaiv zoo tshaj plaws rau cov txheej txheem vuam tshwj xeeb. Qhov no muab cov kev daws teeb meem ntau dua thiab kev lag luam orthopedic. Cov chav kawm ntawm Do-based diffraction-raws li txoj hauv kev no muaj kev tswj xyuas tag nrho ntawm lub zog piv ntawm cov nplhaib sib piv rau cov kev daws teeb meem fiber ntau tam sim no hauv kev ua lag luam, tsis zoo li cov kev daws teeb meem fiber ntau nrog ntau qhov kev txwv tsis pub muaj. Cov qauv no tuaj yeem hloov kho rau cov kab loj loj (15-22 hli inch) feem ntau yog siv rau ntau-kilowatt lasers, piv txwv li cov khoom siv kho qhov muag tuaj yeem ntsia tau rau hauv phau ntawv off-the-shelf los yog hluav taws xob rotating sawv los tsim ib qho kev kho qhov muag. . Xws li modules tuaj yeem muab tso rau ntawm qhov chaw kho qhov muag tom qab lub laser collimator, lossis zoo dua, ncaj qha ntawm qhov nkag ntawm lub taub hau laser lossis scanning system. Cov kev teeb tsa no tso cai rau cov welded optics kom ua tau raws li cov neeg siv hauv cov txheej txheem multimode fiber ntau lasers yam tsis tas yuav suav rau NA loj dua thiab qhov loj dua, kim optics xav tau ib yam li hauv lub nplhaib-hom fiber ntau lasers. Tag nrho cov kev hloov kho tsuas yog yuav tsum tau ua tiav los ntawm kev ua haujlwm ntawm lub rooj sib hloov rau ob peb feeb kom ua tiav qhov kev hloov kho ntawm qhov hloov kho qhov taw qhia annular chaw zog piv. Tsis tas li ntawd, nws yog ib qho tseem ceeb tshwj xeeb tshaj yog rau micro vuam siv ib hom teeb meem beam, vim hais tias cov yam ntxwv uas txwv machining ceev yuav tsis yog lub hwj chim ntawm ib hom fiber ntau, tab sis theej lub hump, porosity, thiab lwm yam teeb meem uas muaj peev xwm. raug txo los ntawm kev hloov ib feem ntawm lub zog laser mus rau thaj tsam annular nyob ib ncig ntawm qhov chaw. Tsis tas li ntawd, lub nplhaib Lub kaum sab xis ntawm nws qhov kev daws teeb meem yog qhov tsis hnov ​​​​tsw ntawm qhov loj ntawm cov khoom siv hluav taws xob, muab kev yooj yim dua rau shaping. Yog li ntawd, qhov diffraction-based point-ring spot shaping hom muab ntau cov txiaj ntsig rau laser vuam, thiab tib lub sijhawm, nws yooj yim, tsis tshua muaj nqi, thiab muaj zog.
