Fiber optic sib txuas

Fiber optic bundler yog fiber ntau optic connector ntaus ntawv, uas los ntawm cov fiber ntau precision splicing tshuab, thiaj li hais tias lub transmitting fiber ntau outputs ntawm lub optical zog mus rau lub siab tshaj plaws coupling mus rau lub txais fiber ntau, thiab yog li ntawd vim nws cuam tshuam nyob rau hauv txoj kev kho qhov muag thiab lub cuam ​​tshuam rau qhov system yog tsawg.Fiber combiner yog ib qho tseem ceeb nyob rau hauv lub fiber laser system, nws zoo tsis tsuas yog ncaj qha txiav txim lub hwj chim ntawm lub fiber laser thiab qhov zoo ntawm cov nqaj, tab sis kuj yog ib qho tseem ceeb guarantee rau kev ruaj ntseg thiab ruaj khov ua hauj lwm ntawm lub laser.

Kev faib tawm ntawm fiber ntau optic bundlers

Raws li kev faib tawm ntawm cov haujlwm siv, fiber ntau optic bundlers tuaj yeem muab faib ua ob pawg: lub zog bundlers thiab cov twj tso kua mis.

(1) Lub twj tso kua mis sib txuas yog tsuas yog siv rau ntau lub twj tso kua mis photosynthetic beam rau hauv qhov tso zis fiber ntau, feem ntau yog siv los ua kom lub zog ntawm lub twj tso kua mis.

(2) Lub hwj chim beam combiner yog muab cov multi-channel ib leeg-hom laser beam rau hauv cov khoom siv fiber ntau rau cov zis, uas yog siv los txhim kho lub zog tso zis ntawm laser.

Raws li kev faib ua feem, fiber ntau bundlers yuav muab faib ua ob pawg: N × 1 fiber bundlers uas tsis muaj teeb liab fibers, thiab (N + 1) × 1 fiber bundlers uas muaj teeb liab fibers.Tsis zoo li N × 1 fiber bundler, qhov kho qhov muag fiber ntau hauv nruab nrab ntawm (N + 1) × 1 fiber bundler yog lub teeb liab fiber ntau.Thaum lub sij hawm fabrication txheej txheem, N fibers yuav tsum nruj nruj thiab symmetrically teem ib ncig ntawm lub teeb liab fiber, thiab lub teeb liab fiber nyob rau hauv nruab nrab yog siv rau lub tswv yim ntawm teeb liab teeb.N × 1 beam combiner muaj ob lub hwj chim beam combiner thiab twj tso kua mis bundler, kev ua haujlwm ntawm qhov sib txawv nyob ntawm hom N-channel input fiber, yog tias N-channel fiber ntau yog ib hom fiber ntau lossis hom loj hom fiber ntau, nws muaj peev xwm txuas ncaj qha rau N lasers.Siv los ua kom lub zog tso zis ntawm lub laser, uas yog, lub hwj chim beam combiner;Yog hais tias N-txoj kev fiber ntau yog fiber ntau multimode, nws txuas nrog N twj tso kua mis los ua kom lub zog twj tso kua mis ntawm laser, uas yog, lub twj tso kua mis sib xyaw.

▲ N × 1 Fiber Bundler
(N + 1) × 1 Beam Combiner yog ob qho tib si twj tso kua mis bundlers, feem ntau yog siv nyob rau hauv fiber ntau amplification systems.Ib hom fiber ntau nyob rau hauv nruab nrab ntawm lub bundler yog lub teeb liab fiber ntau rau kev sib kis ntawm lub teeb liab, thiab N-channel multimode fiber nyob ib ncig ntawm nws yog lub twj tso kua mis fiber ntau rau kev sib kis ntawm lub teeb ci.Cov bundler no feem ntau siv hauv MOPA cov qauv.

Sab twj tso kua mis bundlers thiab kawg twj tso kua mis bundlers

Qhov nruab nrab ntawm lub twj tso kua mis sab sib txuas yog lub teeb liab fiber ntau, cov tub ntxhais fiber ntau yog ib hom lossis quasi-ib leeg-hom waveguide rau kev xa cov lasers, thiab peripheral rau fibers yog cov twj fibers rau kev siv lub teeb.Lub xya fibers yog zoo zoo npaj thiab melted thiab thinned thiab spliced ​​nrog cov zis ob-clad fiber.

Sab twj tso kua mis bundler txawv ntawm qhov kawg twj tso kua mis bundler nyob rau hauv hais tias lub twj tso kua mis fiber ntau ntawm lub twj tso kua mis bundler yog rub thiab haum rau lub hnab ntawv ntawm lub teeb liab fiber ntau, thaum lub teeb liab fiber yog tsis melted thiab thinned.Yog li ntawd, sab twj tso kua mis combiner teeb liab kis tau tus mob zoo tshaj qhov kawg twj tso kua mis bundler nyob rau hauv txoj cai.

Kev tsim cov kab hluav taws xob sib txuas

Cov qauv yooj yim ntawm lub hwj chim bundler feem ntau suav nrog peb ntu: cov khoom siv fiber ntau, fusion conical fiber ntau thiab cov zis fiber ntau.

Ua ntej tshaj plaws, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau ua kom zoo welded nrog cov zis fiber ntau tom qab melting thiab rub lub khob hliav qab, nws yuav tsum tau ua kom lub hlaws ntawm lub pob fiber ntau yog ncig, thiab lub twj tso kua mis fiber ntau yog nruj nreem teem rau hauv ib qho. tej yam geometric txoj kev, feem ntau cov fiber yog nruj nreem teem nyob rau hauv ib tug zoo hexagonal yam.Thaum lub sij hawm tsim cov txheej txheem, cov khoom siv fiber ntau yog thawj zaug noj, thiab tom qab ntawd cov khoom siv fiber ntau ntawm cov pob khoom yog melted thiab taped los tsim ib lub khob fiber ntau, thiab tom qab ntawd lub khob hliav qab ib feem ntawm lub khob hliav qab fiber ntau yog txiav thiab spliced ​​nrog lub khob hliav qab fiber ntau. tso zis fiber ntau.Thaum kawg, lub pob tsim nyog thiab cov qauv thermal yog tsim los xyuas kom meej tias cov nqaj sib txuas tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev.Hlau tooj liab lossis txhuas uas muaj thermal conductivity feem ntau yog siv los ua vaj tse rau encapsulation thiab cua sov dissipation, thiab yog tias tsim nyog, cov qauv dej txias yog tsim los ntawm cov hlau encapsulation.Fiber lasers yog spliced ​​mus cuag kev sib txuas ntawm fiber optic li.Txhawm rau kom cov lasers ua tiav lub zog ntau dua, kev ua haujlwm zoo fiber ntau yog qhov tseem ceeb heev.Thaum lub sij hawm fusion ntawm fibers, poob yog inevitably tshwm sim uas accumulates lub teeb thiab tshav kub thaum lub sij hawm laser ua hauj lwm, uas yuav ua tau kom beam zoo degradation los yog puas rau optics.Guanghui Laser txais qhov tshwj xeeb weld point thermal tswj thev naus laus zis los kov yeej cov teeb meem kev ua haujlwm ntawm lub zog thermal tshuav nyiaj li cas, thiab dhau los ntawm tag nrho cov thermal tswj simulation optimization thiab cov dej txias tsim tshiab, nws tuaj yeem ua kom muaj kev ruaj ntseg ntev ntawm lub laser.
