Sapphire Optical Fiber Light Transmission Extreme Environments

Kev Piav Qhia Luv:

Sapphire Optical Fiber yog ib qho kev ua tau zoo ib leeg-crystal kis tau tus mob nruab nrab tsim rau cov ntawv thov kho qhov muag uas xav tau kev ua haujlwm ntev, kev tiv taus kub, thiab kev ruaj khov spectral. Tsim los ntawmpob zeb sapphire tsim (ib lub pob zeb siv lead ua los ntawm txhuas oxide, Al₂O₃), cov fiber no xa cov kev sib kis optical sib xws los ntawmpom tau rau thaj chaw nruab nrab infrared (0.35–5.0 μm), deb tshaj qhov txwv ntawm cov fibers silica ib txwm muaj.

Kev Taw Qhia

Vim nwscov qauv monocrystalline, sapphire fiber ua rau muaj kev tiv taus cua sov, siab, xeb, thiab hluav taws xob zoo heev. Nws ua rau muaj kev sib kis teeb liab ruaj khov hauv qhov chaw nyuaj thiab muaj kev cuam tshuam uas cov fibers ib txwm yuav yaj, lwj, lossis poob pob tshab.

Cov Yam Ntxwv Sib Txawv

Kev Tiv Thaiv Thermal Tsis Sib Xws
Sapphire optical fibers khaws cia optical thiab mechanical integrity txawm tias thaum raug raukub tshaj 2000 ° C, ua rau lawv tsim nyog rau kev saib xyuas hauv qhov chaw hauv cov cub tawg, turbines, thiab cov chav sib txuas.
Qhov Rai Spectral Dav Dav
Cov khoom siv txhawb nqa kev xa hluav taws xob zoo los ntawm ultraviolet mus rau nruab nrab infrared wavelengths, tso cai rau kev siv yooj yim hauvKev siv spectroscopy, pyrometry, thiab kev soj ntsuam.
Kev Ruaj Kho Siab
Cov qauv siv lead ua ib leeg muab lub zog tensile siab thiab tiv taus kev tawg, ua kom ntseeg tau tias muaj kev ntseeg siab hauv qab kev co, kev poob siab, lossis kev ntxhov siab ntawm lub tshuab.
Kev Ruaj Ntseg Tshuaj Zoo Tshaj Plaws
Tiv taus cov kua qaub, alkalis, thiab cov pa roj reactive, cov sapphire fibers ua haujlwm tau zoo hauv cov huab cua uas muaj tshuaj lom neeg, suav nrogoxidizing los yog txo cov chaw ib puag ncig.
Cov Khoom Siv Uas Tau Kho Kom Ruaj Khoov Los Ntawm Kev Hluav Taws Xob
Sapphire yog inherently immune rau darkening los yog degradation nyob rau hauv ionizing hluav taws xob, ua rau nws zoo tagnrho raukev tsim kho dav hlau, nuclear, thiab kev tiv thaivkev ua haujlwm.

Kev Tsim Khoom Siv Tshuab

Sapphire optical fibers feem ntau yog tsim los ntawm kev sivKev Loj Hlob Pedestal Uas Muaj Laser-Heated (LHPG) or Kev Loj Hlob Uas Muaj Ntug (EFG)cov txheej txheem. Thaum lub sijhawm loj hlob, cov noob siv lead ua sapphire raug cua sov kom tsim tau ib cheeb tsam me me thiab tom qab ntawd rub mus rau sab saud ntawm qhov nrawm tswj kom tsim tau ib lub fiber nrog lub cheeb tsam sib npaug thiab kev taw qhia siv lead ua zoo meej.
Cov txheej txheem no tshem tawm cov ciam teb ntawm cov noob thiab cov khoom tsis huv, ua rau muajtsis muaj qhov tsis zoo ib leeg-siv lead ua fiber. Qhov saum npoo ces raug polished, annealed, thiab xaiv coated nrogcov txheej tiv thaiv lossis cov txheej cuam tshuamlos txhim kho kev ua tau zoo thiab kev ua haujlwm ntev.
