Kev Tshawb Fawb Kev Tshawb Fawb ntawm Cov Hluav Taws Xob Lasers

Txhim Kho NtawmFiber laserlub tsev

1, Chaw Chaw Lub Teeb Twj Qauv Qauv

Thaum Ntxov Fiber Ntau Ntau Siv Optical Tso Kua Qis,laserCov zis, nws cov zis zog yog tsawg, txhawm rau kom sai heev txhim kho cov zis hluav taws xob ntawm lub sijhawm luv luv ntawm lub sijhawm luv luv muaj teeb meem ntau dua. Nyob rau hauv xyoo 1999, cov zis zog ntawm cov fiber ntau laser baser, kev ua qauv ntawm cov resonator bidirectional, nrog kev tshawb nrhiav ntawm txoj kab nqes ntawm cov fiber Laser hu 58.3%.
Txawm li cas los xij, txawm hais tias siv cov ntxig roj teeb Thaum lub laser yuav tsum tau txav mus los hauv txoj kev kho kho qhov muag, tom qab ntawd txoj kev kho kho kho qhov muag tseem xav tau rov qab kho qhov muag lub twj tso kua mis qauv fiber ntau.

2, ncaj qha oscillator qauv thiab mopa qauv

Nrog rau kev txhim kho ntawm fiber ntau lub zog, cladding fais fab tuag, sim kho cov txheej txheem kev txhim kho ntawm cov txij nkawm kev ua haujlwm ntawm fiber ntau. Qhov kev txhim kho no tau cov cim cov cim kev kawm tiav ntawm cov lis dej num fiber ntau. Ncaj Ncees Oscillator qauv thiab Mopa qauv yog ob qho qauv ntawm cov txheej txheem fiber ntau ntawm kev ua lag luam. Tus qauv Oscillator ncaj qha yog tias Grating xaiv lub wavelength nyob rau hauv cov txheej txheem xaiv los ntawm lub noob txiv tau xaiv los ntawm lub noob teeb, thiab lub noob teeb tau nthuav dav nyob rau hauv kev ua ntawm thawj -Level amplifier, yog li cov zis zog ntawm cov fiber ntau laser tseem yuav tau txhim kho rau qee yam. Rau lub sijhawm ntev, fiber ntau nrog cov qauv kws mpoa tau siv los ua cov qauv uas nyiam tshaj plaws rau cov roj muaj zog siab. Txawm li cas los xij, cov kev tshawb fawb tom qab tau pom tias lub zog hluav taws xob hauv cov qauv hluav taws xob yuav muaj kev cuam tshuam rau qee yam, uas tseem muaj kev cuam tshuam ncaj qha Ntawm lub high-fais fab tso zis.

Nrog rau kev txhim kho cov tshuab ua twj

Lub twj tso cua wavelong ntawm thaum ntxov ytterbium-enped fiber ntau laser yog feem ntau 915nm lossis ob qho kev nqus ncaj qha, yog li nws tau siv dav dav vim yog cov noob poob. Hauv-band twj siab thev naus laus zis yog kev txuas ncaj qha ntawm cov nthwv dej wavelength thiab cov noob quanum poob qis dua qhov kev ua haujlwm ncaj qha.

Muaj Zog Fais Fiber LaserTshuab Kev Tsim Kho Tshuab Botteneneck

Txawm hais tias fiber ntau muaj cov ntawv thov muaj txiaj ntsig zoo ntawm kev ua haujlwm fiber ntau ntxiv, tab sis yog tias koj xav ua kom muaj kev txhawb nqa fiber ntau, tab sis yog tias koj xav ua kom muaj kev tawm tsam fiber ntau ntxiv tuaj yeem tso tawm zog ntau dua, tseem tshuav Ntau lub raj mis nyob rau hauv cov thev naus laus zis uas twb muaj lawm. Piv txwv li, seb cov zis siv zog ntawm cov fiber ntau laser tuaj yeem ncav cuag ib leeg-fiber ib hom-hom 36.6kw; Cov cawv ntawm cov twj tso kua mis ntawm cov fiber ntau lub zog tso tawm; Tus cawv ntawm thermal lens nyhuv ntawm cov zis zog ntawm fiber ntau laser.

Ib qho ntxiv, kev tshawb fawb ntawm ntau lub zog tsim tawm thev naus laus zis ntawm fiber ntau laser tseem yuav tsum xav txog qhov muaj kev ruaj khov ntawm hom kev hloov pauv. Los ntawm kev tshawb nrhiav, nws yog qhov tseeb tias qhov cuam tshuam ntawm kev hloov pauv ntawm cov hluav taws xob tsis yooj yim yog hais txog thaum muaj zog lossis ntau lub zog, cov zis hluav taws xob yuav qhia a Kev poob nrawm dua, thiab muaj qee qhov kev txwv ntawm kev txwv ntawm kev ua kom muaj zog ntau dua ntawm cov fiber ntau laser.

Txawm hais tias cov ua rau muaj tseeb ntawm lub photon dogening cov nyhuv tsis tau hais meej tias cov neeg feem coob ntseeg tau qhov tshwm sim tuaj yeem ua rau muaj qhov tshwm sim ntawm lub photon darkening nyhuv. Ntawm ob qho no, cov kev hauv qab no tau npaj tseg rau inhibit photo amazing nyhuv. Xws li txhuas, phosphorus, thiab lwm yam, yog li kom zam rau kev hloov lub zog 3kW yog los tswj hwm 3kw lub zog ruaj khov ruaj khov rau 100 teev.
