Kev hloov pauv ntawm cov lasers fiber ntau zog

Kev ua kom zoo dua ntawmlaser fiberqauv

1, qhov chaw teeb pom kev zoo twj tso kua mis qauv

Cov laser fiber thaum ntxov feem ntau siv cov zis twj tso kua mis optical,laserCov zis tawm, nws lub zog tso zis tsawg, txhawm rau txhim kho lub zog tso zis ntawm cov lasers fiber sai sai hauv lub sijhawm luv luv muaj qhov nyuaj dua. Xyoo 1999, lub zog tso zis ntawm kev tshawb fawb thiab kev txhim kho fiber laser tau tawg 10,000 watts thawj zaug, cov qauv ntawm cov laser fiber feem ntau yog siv cov twj tso kua mis bidirectional, tsim cov resonator, nrog rau kev tshawb nrhiav ntawm qhov ua tau zoo ntawm cov laser fiber tau txog 58.3%.
Txawm li cas los xij, txawm hais tias kev siv lub teeb twj fiber ntau thiab cov thev naus laus zis laser txuas los tsim cov lasers fiber tuaj yeem txhim kho lub zog tso zis ntawm cov lasers fiber, tab sis tib lub sijhawm muaj qhov nyuaj, uas tsis zoo rau lub lens kho qhov muag los tsim txoj kev kho qhov muag, thaum lub laser xav tau tsiv mus rau hauv cov txheej txheem ntawm kev tsim txoj kev kho qhov muag, ces txoj kev kho qhov muag kuj yuav tsum tau rov kho dua, uas txwv tsis pub siv dav ntawm cov qauv twj optical fiber lasers.

2, cov qauv oscillator ncaj qha thiab cov qauv MOPA

Nrog rau kev tsim cov fiber lasers, cladding power strippers tau maj mam hloov cov khoom siv lens, ua kom yooj yim rau cov kauj ruam kev tsim kho ntawm fiber lasers thiab tsis ncaj qha txhim kho kev saib xyuas kev ua haujlwm ntawm fiber lasers. Qhov kev hloov pauv no yog lub cim ntawm kev ua tau zoo ntawm fiber lasers. Cov qauv oscillator ncaj qha thiab cov qauv MOPA yog ob qho qauv feem ntau ntawm fiber lasers hauv kev ua lag luam. Cov qauv oscillator ncaj qha yog tias lub grating xaiv qhov wavelength hauv cov txheej txheem ntawm oscillation, thiab tom qab ntawd tso tawm qhov wavelength xaiv, thaum MOPA siv qhov wavelength xaiv los ntawm grating ua lub teeb noob, thiab lub teeb noob tau amplified nyob rau hauv qhov kev ua ntawm thawj-theem amplifier, yog li lub zog tso zis ntawm fiber laser kuj tseem yuav raug txhim kho rau qee qhov. Rau lub sijhawm ntev, fiber lasers nrog MPOA qauv tau siv ua cov qauv nyiam rau cov fiber lasers muaj zog siab. Txawm li cas los xij, kev tshawb fawb tom qab tau pom tias cov zis muaj zog siab hauv cov qauv no yooj yim ua rau tsis ruaj khov ntawm qhov chaw faib tawm hauv fiber laser, thiab qhov ci ntsa iab laser tso zis yuav raug cuam tshuam rau qee qhov, uas kuj muaj kev cuam tshuam ncaj qha rau cov nyhuv tso zis muaj zog siab.

Nrog rau kev txhim kho ntawm cov thev naus laus zis twj tso kua mis

Lub wavelength ntawm cov laser fiber ytterbium-doped thaum ntxov feem ntau yog 915nm lossis 975nm, tab sis ob lub wavelength ntawm cov twj tso kua mis no yog cov ncov ntawm ytterbium ions, yog li nws hu ua kev twj tso kua mis ncaj qha, kev twj tso kua mis ncaj qha tsis tau siv dav vim yog qhov poob quantum. Kev siv tshuab twj tso kua mis hauv-band yog kev txuas ntxiv ntawm kev siv tshuab twj tso kua mis ncaj qha, uas qhov wavelength ntawm qhov wavelength ntawm kev twj tso kua mis thiab qhov wavelength xa mus zoo sib xws, thiab qhov poob quantum ntawm kev twj tso kua mis hauv-band me dua li ntawm kev twj tso kua mis ncaj qha.

Lub zog siab fiber laserkev loj hlob ntawm thev naus laus zis

Txawm hais tias cov lasers fiber muaj txiaj ntsig zoo rau kev siv tub rog, kev kho mob thiab lwm yam lag luam, Tuam Tshoj tau txhawb nqa kev siv dav dav ntawm cov lasers fiber los ntawm ze li ntawm 30 xyoo ntawm kev tshawb fawb thiab kev txhim kho thev naus laus zis, tab sis yog tias koj xav ua kom cov lasers fiber tuaj yeem tso zis hluav taws xob siab dua, tseem muaj ntau qhov teeb meem hauv cov thev naus laus zis uas twb muaj lawm. Piv txwv li, seb lub zog tso zis ntawm cov laser fiber puas tuaj yeem ncav cuag ib hom fiber ib leeg 36.6KW; Kev cuam tshuam ntawm lub zog twj tso zis ntawm cov laser fiber tso zis hluav taws xob; Kev cuam tshuam ntawm cov nyhuv thermal lens rau lub zog tso zis ntawm cov laser fiber.

Ntxiv mus, kev tshawb fawb ntawm cov thev naus laus zis siab dua ntawm cov laser fiber yuav tsum xav txog qhov ruaj khov ntawm hom transverse thiab cov nyhuv tsaus ntuj photon. Los ntawm kev tshawb nrhiav, nws yog qhov tseeb tias qhov cuam tshuam ntawm qhov tsis ruaj khov ntawm hom transverse yog cov cua sov fiber, thiab cov nyhuv tsaus ntuj photon feem ntau yog hais txog thaum lub laser fiber txuas ntxiv tso tawm ntau pua watts lossis ntau kilowatts ntawm lub zog, lub zog tso zis yuav qhia txog kev poob qis sai, thiab muaj qee qib ntawm kev txwv ntawm cov zis siab tas mus li ntawm cov laser fiber.

Txawm hais tias qhov ua rau muaj qhov cuam tshuam ntawm photon tsaus ntuj tsis tau txhais meej meej tam sim no, feem ntau cov neeg ntseeg tias qhov chaw tsis zoo ntawm cov pa oxygen thiab kev nqus ntawm cov nqi hloov pauv tuaj yeem ua rau muaj qhov cuam tshuam ntawm photon tsaus ntuj. Ntawm ob yam no, cov hauv qab no tau pom zoo los tiv thaiv cov teebmeem ntawm photon tsaus ntuj. Xws li txhuas, phosphorus, thiab lwm yam, kom tsis txhob nqus cov nqi hloov pauv, thiab tom qab ntawd cov fiber ntau zoo tshaj plaws raug sim thiab siv, tus qauv tshwj xeeb yog kom tswj tau 3KW lub zog tso zis rau ob peb teev thiab tswj tau 1KW lub zog tso zis ruaj khov rau 100 teev.
