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 1999, cov zis zog ntawm cov fiber ntau las kev nqus tau tawg 10,000 qhov kev tshawb nrhiav ntawm cov kab nqes kev ua tau zoo ntawm cov fiber ntau laser hu rau 58.3%.
Txawm li cas los xij, txawm hais tias siv cov ntxig roj teeb ntawm lub zog los tsim kho cov txheej txheem kho qhov muag, tab sis yuav tsum tau ua kom haum rau cov kev siv kho qhov muag ntawm kev kho qhov muag

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 kev sib haum xeeb xaiv lub wavelength, thiab tom qab ntawd lub teeb pom kev zoo, yog li cov khoom tawm hluav taws xob tau txais txiaj ntsig zoo, yog li cov khoom tawm hluav taws xob tau txhim kho kom muaj 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 no yog qhov cuam tshuam rau qee yam, thiab cov zis ua kom ncaj qha rau cov khoom siv hluav taws xob kom ncaj qha.

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 Bottenenck

Txawm hais tias cov lasers fiber ntau muaj cov ntawv nyeem muaj txiaj ntsig zoo ntawm kev ua haujlwm fiber ntau, tab sis yog tias koj tseem muaj ntau ntau lub raj mis muaj zog hauv cov thev naus laus zis. 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 kev cuam tshuam ntawm kev sim siab, thiab muaj lub zog ua kom muaj zog ntxiv rau ntau pua qhov kev tso zis ntau dua los yog muaj cov khoom siv hluav taws xob ntau dua li cov khoom siv hluav taws xob nrawm

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.
