Sapphire fiber ib leeg siv lead ua Al₂O₃ siab optical transmittance melting point 2072 ℃ siv tau rau laser qhov rais ntaub ntawv Featured Duab

Kev Piav Qhia Luv:

Sapphire fiber yog ua los ntawm ib leeg siv lead ua alumina (Al₂O₃), uas yog cov khoom siv uas muaj zog heev, tshuaj lom neeg tsis kam thiab thermal conductivity zoo. Sapphire yog cov qauv siv lead ua hexagonal, qhov sib kis ntawm lub teeb yog 0.146.0μm, thiab muaj kev xa hluav taws xob siab hauv 3.05.0μm band. Lub ntsiab lus yaj ntawm sapphire yog siab txog 2072 ° C, thiab qhov nyuaj yog qhov thib ob tsuas yog pob zeb diamond, yog li sapphire fiber muaj kev tiv thaiv kub heev thiab lub zog kho tshuab.

Cov yam ntxwv

Cov txheej txheem npaj

1. Feem ntau cov fiber sapphire yog npaj los ntawm laser heated base method (LHPG). Los ntawm txoj kev no, sapphire fiber nrog geometric axis thiab C-axis tuaj yeem cog tau, uas muaj kev xa mus zoo hauv ze infrared band. Qhov poob feem ntau yog los ntawm kev tawg ua los ntawm cov khoom siv crystal uas muaj nyob hauv lossis ntawm qhov chaw ntawm cov fiber.

2. Kev npaj cov silica clad sapphire fiber: Ua ntej, poly (dimethylsiloxane) txheej yog teeb tsa rau ntawm qhov chaw ntawm sapphire fiber thiab kho, thiab tom qab ntawd cov txheej kho tau hloov mus ua silica ntawm 200 ~ 250 ℃ kom tau txais silica clad sapphire fiber. Txoj kev no muaj qhov kub thiab txias qis, kev ua haujlwm yooj yim thiab kev ua haujlwm zoo.

3. Kev npaj cov fiber sapphire cone: Lub laser cua sov txoj kev loj hlob lub cuab yeej siv los npaj cov fiber sapphire cone los ntawm kev tswj qhov ceev ntawm cov noob siv lead ua sapphire fiber thiab qhov ceev ntawm cov pas nrig siv lead ua sapphire. Txoj kev no tuaj yeem npaj cov fiber sapphire conical nrog cov tuab sib txawv thiab qhov kawg zoo, uas tuaj yeem ua tau raws li cov kev xav tau ntawm daim ntawv thov tshwj xeeb.

Cov hom fiber thiab cov lus qhia

1. Qhov ntau thiab tsawg: Lub cheeb ntawm sapphire fiber tuaj yeem xaiv tau ntawm 75 ~ 500μm kom hloov kho rau cov kev xav tau ntawm daim ntawv thov sib txawv.

2. Cov fiber conical: Cov fiber sapphire conical tuaj yeem ua tiav kev sib kis lub zog siab thaum ua kom ntseeg tau tias cov fiber yooj ywm. Cov fiber no txhim kho kev sib kis lub zog yam tsis muaj kev txi kev yooj ywm.

3. Bushings thiab connectors: Rau cov fibers optical uas muaj lub cheeb tshaj 100μm, koj tuaj yeem xaiv siv polytetrafluoroethylene (PTFE) bushings lossis optical fiber connectors rau kev tiv thaiv lossis kev sib txuas.

Daim ntawv thov teb

1. Lub ntsuas kub fiber ntau: Sapphire fiber vim nws tiv taus kub siab, tiv taus tshuaj lom neeg, tsim nyog rau kev ntsuas fiber hauv qhov chaw kub siab. Piv txwv li, hauv metallurgy, kev lag luam tshuaj lom neeg, kev kho cua sov thiab lwm yam teb, sapphire fiber kub siab sensors tuaj yeem ntsuas qhov kub txog li 2000 ° C.

2. Kev hloov pauv zog laser: Cov yam ntxwv ntawm kev xa hluav taws xob siab ntawm sapphire fiber ua rau nws siv dav hauv kev hloov pauv zog laser. Nws tuaj yeem siv ua cov khoom siv qhov rai rau lasers kom tiv taus cov hluav taws xob laser muaj zog thiab qhov kub thiab txias.

3. Kev ntsuas kub hauv kev lag luam: Hauv kev ntsuas kub hauv kev lag luam, cov khoom siv ntsuas kub siab sapphire fiber tuaj yeem muab cov ntaub ntawv ntsuas kub kom raug thiab ruaj khov, uas pab saib xyuas thiab tswj kev hloov pauv kub hauv cov txheej txheem ntau lawm.

4. Kev tshawb fawb txog kev tshawb fawb thiab kev kho mob: Hauv kev tshawb fawb txog kev tshawb fawb thiab kev kho mob, cov fiber sapphire kuj tseem siv rau hauv ntau yam kev ntsuas qhov muag pom tseeb thiab kev siv tshuaj vim nws cov khoom siv lub cev thiab tshuaj lom neeg tshwj xeeb.
