BWT tau npaj siab xav txog qhov kev xav tsis muaj tseeb (DSBC) thiab txheeb xyuas qhov tseeb ntawm DSBC los ntawm kev sim ntawm kilowatt-theem twj tso kua mis.Tam sim no, lub zog ntawm ib lub raj tau nce mus rau 15W-30W @ BPP≈5-12mm * mrad thiab qhov ua tau zoo ntawm electro-optical yog> 60%, uas ua rau lub zog siab zog twj tso kua mis txuas nrog cov zis fiber ntau kom tswj tau qhov siab. brightness tso zis thaum txo ntim, Nws muaj peev xwm txo qhov hnyav thiab txhim kho qhov kev hloov pauv ntawm electro-optical efficiency.
Siv cov nti tam sim no, BWT tau raws li pom tau hais tias lub twj tso kua mis nrog lub taub hau ntawm 135μm NA0.22 fiber-coupled tso zis 420W wavelength-xauv ntawm 976nm, zoo ≈ 500g;thiab ib tug tub ntxhais txoj kab uas hla ntawm 220μm NA0.22 fiber ntau txuas tso zis 1000W ib wavelength 976nm (los yog 915nm), zoo ≈ 400g twj tso kua mis qhov chaw.
Nyob rau hauv lub neej yav tom ntej, nrog rau kev txhim kho ntawm semiconductor nti brightness thiab electro-optical efficiency, lub teeb yuag thiab high-power twj tso kua mis yuav ua lub luag hauj lwm irreplaceable nyob rau hauv lub tsim ntawm me me-ntim high-power fiber laser teeb qhov chaw, thiab yuav nquag txhawb txoj kev loj hlob. ntawm cov ntawv thov kev lag luam.
Taw qhia
Fiber lasers tau loj hlob sai vim lawv cov nqaj zoo heev thiab hloov tau lub zog nthuav dav (fiber combiners).Nyob rau hauv xyoo tas los no, ib hom ib leeg-fiber fiber ntau lasers raug txwv los ntawm TMI (transverse mode instability) thiab SRS teebmeem, thiab lub zog ntawm semiconductor ncaj qha siv fiber ntau laser oscillators yog txwv rau 5kW.
[1].Lub laser amplifier tseem nres ntawm 10kW
[2].Txawm hais tias cov zis hluav taws xob tuaj yeem nce ntxiv los ntawm qhov tsim nyog nce cov tub ntxhais txoj kab uas hla, qhov tso zis hluav taws xob zoo kuj txo qis -1.Txawm li cas los xij, qhov kev thov rau kev txhim kho qhov ci ntawm semiconductor twj tso kua mis yog tseem ceev.
Cov kev cai rau beam zoo nyob rau hauv kev lag luam daim ntawv thov tsis tas ib hom.Txhawm rau nce lub zog ntawm ib leeg-fiber, ob peb hom kev txiav txim qis tau tso cai.Txog tam sim no, ob peb hom ib leeg-fiber thiab beam-combined multi-mode laser teeb qhov chaw raws li 976nm siv ntau tshaj 5kW Nrog batch daim ntaub ntawv (tsuas yog txiav thiab vuam cov ntaub ntawv hlau), zus tau tej cov coj high-power twj tso kua mis qhov chaw. kuj yog batch-scaled.
Me me, sib dua thiab ruaj khov dua
Kev sib raug zoo ntawm cov semiconductor nti BPP thiab qhov ci ntawm lub twj tso kua mis
Peb xyoos dhau los, qhov ci ci ntawm 9xxnm chips feem ntau yog nyob rau theem ntawm 3W / mm * mrad@12W-100μm strip width & 2W / mm * mrad@18W-200μm strip width.Raws li cov chips no, BWT ua tiav 600W thiab 1000W 200μm NA0.22 fiber-coupled tso zis-1.
Tam sim no, qhov ci ntsa iab ntawm 9xxnm chips tau ua tiav 3.75W / mm * mrad @ 15W-100μm sawb dav & 3W / mm * mrad @ 30W-230μm strip dav, thiab electro-optical efficiency yog tswj ntawm ib ncig ntawm 60%.
Raws li txoj kev xav ntawm qhov ntom ntom ntom ntom [6], nws yog xam raws li qhov nruab nrab fiber ntau coupling efficiency ntawm 78% (laser emission los ntawm cov nti mus rau fiber ntau coupling tso zis: ib leeg-wavelength spatial beam sib txuas thiab polarization beam sib txuas tsis muaj VBG), thiab nws tau xav tias cov nti ua haujlwm ntawm lub zog siab tshaj plaws (Lub nti BPP yog qhov sib txawv ntawm cov dej sib txawv), peb tau sau ib daim ntawv qhia cov ntaub ntawv raws li hauv qab no:
* Chip Brightness VS txawv Core Diameter Fiber Coupling tso zis zog
Nws tuaj yeem pom los ntawm daim duab saum toj no tias thaum ib qho fiber ntau (txoj kab uas hla thiab NA yog tsau) ua tiav cov khoom siv hluav taws xob tshwj xeeb, rau cov chips nrog cov ci ci sib txawv, cov chips txawv, thiab qhov ntim thiab qhov hnyav ntawm lub twj tso kua mis. kuj txawv.Rau cov kev xav tau ntawm kev siv lub tshuab fiber ntau, yog tias lub twj tso kua mis ua los ntawm cov chips saum toj no nrog cov ci ci sib txawv raug xaiv, qhov hnyav thiab ntim ntawm cov fiber ntau laser ntawm tib lub zog sib txawv kiag li, thiab kev teeb tsa ntawm cov dej txias txias kuj yog. txawv heev.
Kev ua haujlwm siab, qhov me me thiab lub teeb yuag yog qhov kev tsis pom kev hauv kev txhim kho lub teeb pom kev zoo yav tom ntej (xws li diode lasers, solid-state lasers lossis fiber ntau lasers), thiab qhov ci ntsa iab, kev ua haujlwm thiab lub zog ntawm semiconductor chips ua lub luag haujlwm txiav txim siab hauv nws. .
Lub teeb yuag, siab ci, siab zog twj tso kua mis qhov chaw
Txhawm rau hloov kho rau cov fiber ntau sib txuas, peb xaiv cov fiber ntau cov ntsiab lus: 135μm NA0.22 thiab 220μm NA0.22.Kev tsim kho kho qhov muag ntawm ob lub twj tso kua mis tau txais kev saib xyuas tsis zoo thiab polarization nqaj sib txuas.
Ntawm lawv, 420WLD txais 3.75W / mm * mrad@15W nti thiab 135μm NA0.22 fiber ntau, thiab muaj VBG wavelength locking, uas ua tau raws li qhov yuav tsum tau muaj ntawm 30-100% lub zog yoj xauv, thiab electro-optical efficiency yog 41%. .LD lub cev yog ua los ntawm cov khoom siv aluminium alloy thiab cov qauv sandwich [5].Cov chips sab sauv thiab sab qis qhia cov dej txias channel, uas txhim kho qhov chaw siv.Lub teeb pom kev zoo, spectrum thiab lub zog tso zis (lub zog hauv fiber ntau) tau qhia hauv daim duab:
* 420W @ 135μm NA0.22 LD
Peb xaiv 6 LDs rau kev ntsuas kub thiab qis thiab kev vibration.Cov ntaub ntawv xeem yog raws li nram no:
* Kev ntsuas kub thiab qis qis
* Kev vibration test
Lub 1000WLD txais yuav 3W / mm * mrad@30W nti thiab 220μm NA0.22 fiber ntau, uas ua tiav 915nm thiab 976nm fiber-coupled tso zis ntawm 1000W feem, thiab electro-optical efficiency yog> 44%.Lub LD lub cev kuj yog ua los ntawm cov khoom siv aluminium alloy.Txhawm rau kom ua raws li qhov sib piv ntawm lub zog-rau-ntau dua, LD plhaub tau yooj yim nyob rau hauv cov xwm txheej ntawm kev ua kom lub zog ntawm cov qauv.Qhov zoo ntawm LD, qhov chaw teeb tsa thiab tso zis hluav taws xob (lub zog hauv fiber ntau) yog raws li hauv qab no:
* 1000W @ 220μm NA0.22 LD
Txhawm rau txhim kho qhov kev ntseeg siab ntawm lub twj tso kua mis, qhov sib txuas kawg fiber ntau siv quartz kawg cap fusion thiab cladding lub teeb lim tshuab, uas ua rau qhov kub ntawm cov fiber ntau sab nraud ntawm lub twj tso kua mis ze ntawm chav tsev kub.Rau 976nmLDs raug xaiv rau kev ntsuas kub thiab qis qis thiab kev vibration.Cov txiaj ntsig kev xeem yog raws li nram no:
* Kev ntsuas kub thiab qis qis
* Kev ntsuas kub thiab qis qis
* Kev vibration test
Xaus
Kev ua kom muaj qhov ci ntsa iab los ntawm kev siv hluav taws xob kho qhov muag, uas yog, lub zog tso zis ntau tshaj plaws thiab qhov ua tau zoo tshaj plaws electro-optical tsis tuaj yeem tau txais tib lub sijhawm, uas yog txiav txim siab los ntawm cov nti ci ci thiab cov zaus zaus ntawm kev sib txuas. fiber ntau.Nyob rau hauv multi-ib leeg-tube spatial beam combining thev naus laus zis, qhov ci ntsa iab thiab kev ua haujlwm zoo ib txwm yog lub hom phiaj uas tsis tuaj yeem ua tiav tib lub sijhawm.Qhov sib npaug ntawm electro-optical efficiency thiab lub zog yuav tsum tau txiav txim siab raws li daim ntawv thov tshwj xeeb.
