Q-hloov Laser thiab MOPA Laser

Nyob rau hauv xyoo tas los no, daim ntawv thov ntawm pulsed fiber ntau lasers nyob rau hauv lub tshav pob ntawm laser marking tau tsim sai heev, ntawm cov kev siv nyob rau hauv lub teb ntawm hluav taws xob 3C khoom, machinery, zaub mov, ntim, thiab lwm yam.

Tam sim no, hom pulsed fiber ntau lasers siv nyob rau hauv laser npav nyob rau hauv kev ua lag luam mas suav nrog Q-hloov tshuab thiab MOPA tshuab.MOPA (Master Oscillator Power-Amplifier) ​​laser yog hais txog lub laser qauv uas lub laser oscillator thiab lub amplifier yog cascaded.Hauv kev lag luam, MOPA laser hais txog qhov tshwj xeeb thiab ntau dua "ntse" nanosecond pulse fiber ntau laser muaj li ntawm semiconductor laser noob los ntawm hluav taws xob pulses thiab fiber ntau amplifier.Nws "kev txawj ntse" feem ntau yog tshwm sim nyob rau hauv cov zis pulse dav yog nws tus kheej adjustable (ntau 2ns-500ns), thiab repetition zaus yuav siab li megahertz.Cov noob qoob loo ntawm Q-hloov fiber ntau laser yog ntxig rau qhov poob modulator nyob rau hauv fiber oscillator kab noj hniav, uas generates ib tug nanosecond mem tes lub teeb tso zis nrog ib tug tej yam mem tes dav los ntawm lub sij hawm modulating lub optical poob hauv kab noj hniav.

Internal qauv ntawm lub laser

Cov qauv sab hauv sib txawv ntawm MOPA fiber ntau laser thiab Q-hloov fiber ntau laser feem ntau yog nyob rau hauv ntau tiam txheej txheem ntawm mem tes noob teeb teeb liab.MOPA fiber ntau laser pulse noob optical teeb liab yog tsim los ntawm hluav taws xob pulse tsav semiconductor laser nti, uas yog, qhov tso zis optical teeb liab yog modulated los ntawm kev tsav hluav taws xob teeb liab, yog li nws muaj zog heev rau kev tsim cov mem tes sib txawv (mem tes dav, repetition zaus. , mem tes waveform thiab lub zog, thiab lwm yam.) Flexibility.Lub pulse noob optical teeb liab ntawm Q-hloov fiber ntau laser generates pulse lub teeb tso zis los ntawm ib ntus nce los yog txo cov optical poob nyob rau hauv resonant kab noj hniav, nrog ib tug yooj yim qauv thiab tus nqi kom zoo dua.Txawm li cas los xij, vim muaj kev cuam tshuam ntawm Q-hloov cov cuab yeej, cov ntsuas pulse muaj qee yam kev txwv.

Output optical tsis

MOPA fiber ntau laser tso zis mem tes dav yog nws tus kheej adjustable.Cov mem tes dav ntawm MOPA fiber ntau laser muaj qhov tunability (ntau 2ns ~ 500 ns).Qhov nqaim ntawm lub mem tes dav, qhov me me ntawm thaj chaw muaj kev kub ntxhov, thiab kev ua haujlwm siab dua tuaj yeem tau txais.Cov zis pulse dav ntawm Q-hloov fiber ntau laser tsis kho, thiab cov mem tes dav feem ntau tas li ntawm tus nqi ruaj khov ntawm 80 ns thiab 140 ns.MOPA fiber ntau laser muaj qhov dav dua qhov ntau zaus.Qhov zaus ntawm MOPA laser tuaj yeem ncav cuag qhov tso zis ntau zaus ntawm MHz.High repetition zaus txhais tau hais tias muaj kev ua haujlwm siab, thiab MOPA tseem tuaj yeem tswj hwm lub zog siab tshaj plaws nyob rau hauv cov xwm txheej ntau zaus.Q-hloov fiber ntau laser raug txwv los ntawm kev ua haujlwm ntawm Q hloov, yog li cov zis ntau zaus nqaim, thiab qhov siab zaus tsuas yog ncav cuag ~ 100 kHz.

Daim ntawv thov scenario

MOPA fiber ntau laser muaj qhov dav parameter hloov ntau yam.Yog li ntawd, nyob rau hauv tas li ntawd mus rau npog cov kev siv ntawm cov pa nanosecond lasers, nws kuj siv tau nws cov cim nqaim mem tes dav, siab repetition zaus, thiab siab ncov hwj chim mus cuag ib co tshwj xeeb precision ua daim ntaub ntawv.xws li:

1.Application ntawm nto stripping ntawm txhuas oxide ntawv

Niaj hnub no cov khoom siv hluav taws xob tau dhau los ua nyias thiab sib dua.Ntau lub xov tooj ntawm tes, ntsiav tshuaj, thiab khoos phis tawj siv nyias thiab lub teeb aluminium oxide ua lub plhaub khoom.Thaum siv Q-hloov laser los kos cov haujlwm ua haujlwm ntawm lub phaj nyias nyias, nws yooj yim ua rau deformation ntawm cov khoom, uas ua rau "convex hulls" nyob rau sab nraub qaum, cuam tshuam ncaj qha rau kev zoo nkauj ntawm cov tsos.Kev siv MOPA laser qhov me me pulse dav tsis tuaj yeem ua rau cov khoom tsis yooj yim rau deform, thiab cov shading yog qhov muag heev thiab ci dua.Qhov no yog vim hais tias MOPA laser siv lub me me mem tes dav parameter kom lub laser nyob rau ntawm cov khoom luv luv, thiab nws muaj zog txaus kom tshem tawm cov anode txheej, yog li rau cov txheej txheem ntawm stripping lub anode nyob rau saum npoo ntawm nyias aluminium oxide. phaj, MOPA Lasers yog qhov kev xaiv zoo dua.

2.Anodized aluminium blackening daim ntawv thov

Siv cov lasers los kos cov cim lag luam dub, qauv, ntawv, thiab lwm yam ntawm cov khoom siv aluminium anodized, es tsis txhob siv cov tshuab inkjet thiab silk screen, nws tau siv dav hauv cov plhaub ntawm cov khoom siv hluav taws xob digital.

Vim tias MOPA pulsed fiber ntau laser muaj qhov dav dav dav dav thiab rov ua dua zaus hloov kho ntau yam, kev siv cov mem tes dav dav thiab qhov tsis muaj zaus tuaj yeem khij lub npoo ntawm cov khoom siv nrog cov nyhuv dub.Cov kev sib txawv ntawm cov kev sib txawv kuj tseem tuaj yeem kos cov qib grey sib txawv.nyhuv.

Yog li ntawd, nws muaj kev xaiv ntau dua rau cov txheej txheem cuam tshuam ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov xim dub thiab txhais tes, thiab nws yog lub teeb pom kev zoo rau blackening anodized aluminium ntawm lub khw.Kev kos npe yog ua nyob rau hauv ob hom: dot hom thiab hloov dot zog.Los ntawm kev kho qhov ceev ntawm cov dots, qhov sib txawv greyscale tuaj yeem simulated, thiab cov duab customized thiab tus kheej cov khoom siv tes ua tuaj yeem raug cim rau ntawm qhov chaw ntawm cov khoom siv txhuas anodized.

3. Xim laser npav

Hauv daim ntawv thov xim stainless hlau, lub laser yuav tsum ua haujlwm nrog me me thiab nruab nrab mem tes dav thiab siab zaus.Kev hloov xim yog feem ntau cuam tshuam los ntawm zaus thiab lub zog.Qhov sib txawv ntawm cov xim no feem ntau cuam tshuam los ntawm tib lub zog pulse ntawm lub laser nws tus kheej thiab qhov sib tshooj ntawm nws qhov chaw ntawm cov khoom.Vim hais tias cov mem tes dav thiab zaus ntawm MOPA laser yog nws tus kheej adjustable, kho ib qho ntawm lawv yuav tsis cuam tshuam rau lwm yam tsis.Lawv koom tes nrog ib leeg kom ua tiav ntau yam, uas tsis tuaj yeem ua tiav los ntawm Q-hloov laser.Nyob rau hauv kev siv tswv yim, los ntawm kev kho cov mem tes dav, zaus, hwj chim, ceev, filling txoj kev, filling spacing thiab lwm yam tsis, permuting thiab combining sib txawv tsis, koj muaj peev xwm kos ntau ntawm nws cov xim los, nplua nuj thiab ilv xim.Ntawm stainless hlau tableware, cov cuab yeej kho mob thiab cov khoom siv tes ua, cov cim zoo nkauj lossis cov qauv tuaj yeem raug cim los ua kom zoo nkauj zoo nkauj.

Feem ntau, cov mem tes dav thiab zaus ntawm MOPA fiber ntau laser tuaj yeem kho tau ntawm nws tus kheej, thiab qhov kev hloov pauv tsis zoo yog qhov loj, yog li kev ua haujlwm zoo, cov nyhuv thermal tsawg, thiab nws muaj qhov zoo tshaj plaws hauv aluminium oxide daim ntawv cim, anodized aluminium. blackening, thiab stainless hlau coloring.Paub txog cov txiaj ntsig uas Q-hloov fiber ntau laser tsis tuaj yeem ua tiav Q-hloov fiber ntau laser yog tus cwj pwm los ntawm cov cim muaj zog, uas muaj qee yam zoo hauv kev sib sib zog nqus engraving ntawm cov hlau, tab sis cov txiaj ntsig zoo kuj ntxhib.Hauv cov ntawv cim npe, MOPA pulsed fiber ntau lasers piv nrog Q-hloov fiber ntau lasers, thiab lawv cov yam ntxwv tseem ceeb tau qhia hauv cov lus hauv qab no.Cov neeg siv tuaj yeem xaiv txoj cai laser raws li qhov xav tau tiag tiag ntawm cov khoom siv thiab cov teebmeem.

MOPA fiber ntau laser mem tes dav thiab zaus yog kho tau ntawm nws tus kheej, thiab qhov kev hloov pauv tsis zoo yog qhov loj, yog li kev ua haujlwm zoo, cov nyhuv thermal tsis tshua muaj, thiab nws muaj qhov zoo tshaj plaws hauv aluminium oxide ntawv cim, anodized aluminium blackening, stainless hlau xim, thiab daim hlau welding.Cov nyhuv uas Q-hloov fiber ntau laser tsis tuaj yeem ua tiav.Q-hloov fiber ntau laser yog tus cwj pwm los ntawm cov cim muaj zog, uas muaj qee yam zoo hauv kev sib sib zog nqus engraving ntawm cov hlau, tab sis cov txiaj ntsig ntawm cov cim yog qhov ntxhib.

Feem ntau, MOPA fiber ntau lasers yuav luag hloov Q-hloov fiber ntau lasers hauv laser high-end npav thiab vuam daim ntaub ntawv.Nyob rau hauv lub neej yav tom ntej, txoj kev loj hlob ntawm MOPA fiber ntau lasers yuav siv sij hawm nqaim mem tes dav thiab ntau dua frequencies raws li cov kev taw qhia, thiab nyob rau tib lub sij hawm taug kev mus rau siab zog thiab siab zog, txuas ntxiv mus ua kom tau raws li cov tshiab yuav tsum tau ntawm laser cov khoom zoo ua, thiab mus txuas ntxiv mus. txhim kho xws li laser derusting thiab lidar.Thiab lwm qhov chaw thov tshiab.
