I-Sapphire Optical Fiber Light Transmission Extreme Environments

I-Sapphire Optical Fiber Light Transmission Extreme Environment Isithombe Esifakiwe

Incazelo emfushane:

I-Sapphire Optical Fiber iwumshini wokudlulisa wekristalu eyodwa osebenza kahle kakhulu owenzelwe izinhlelo zokusebenza ezibonayo ezidinga ukuqina okukhethekile, ukumelana nezinga lokushisa, nokuzinza kokubonwayo. Kwenziwe kusukaisafire yokwenziwa (i-single-crystal aluminium oxide, i-Al₂O₃), le fibre iletha ukudluliswa kwe-optical okungaguquki kusuka ku-kubonakala ezindaweni ezimaphakathi ne-infrared (0.35–5.0 μm), idlula kude imikhawulo yemicu yendabuko esekwe kwi-silica.

Umdwebo onemininingwane

Isingeniso

Ngenxa yayoisakhiwo se-monocrystalline, i-sapphire fiber ikhombisa ukumelana nokushisa, ingcindezi, ukugqwala, kanye nemisebe. Inika amandla ukudluliswa kwesignali okuzinzile ezindaweni ezinokhahlo nezisebenzayo lapho imicu evamile ingancibilika, yonakale, noma ilahlekelwe ukubonakala.

Izici Ezihlukile

I-Thermal Endurance Engenakuqhathaniswa
Imicu ye-Sapphire optical igcina ubuqotho be-optical kanye nemishini ngisho nalapho evezweamazinga okushisa angaphezu kuka-2000°C, okubenza bafaneleke ukugadwa ngaphakathi-situ kuhhavini, izinjini zomoya, namagumbi omlilo.
Iwindi le-Spectral elibanzi
Izinto ezisetshenziswayo zisekela ukudluliswa kokukhanya okuphumelelayo kusuka ku-ultraviolet kuya kumaza amaza amaphakathi ne-infrared, okuvumela ukusetshenziswa okuguquguqukayoi-spectroscopy, i-pyrometry, kanye nezicelo zokuzwa.
High Mechanical Robustness
Isakhiwo sekristalu eyodwa sinikeza amandla aphezulu okuqinile kanye nokumelana nokuqhekeka, okuqinisekisa ukwethembeka ngaphansi kokudlidliza, ukushaqeka, noma ukucindezeleka komshini.
Ukuzinza Kwekhemikhali Okukhethekile
Imelana nama-asidi, ama-alkali, namagesi asebenzayo, imicu yesafire isebenza ngokuphumelelayo emkhathini wamakhemikhali anolaka, okuhlanganisaoxidizing noma ukunciphisa izindawo.
I-radiation-Hardened Material
I-Sapphire ivikelekile ngokwemvelo ekubeni mnyama noma ukonakala ngaphansi kwemisebe ye-ionizing, okuyenza ilungelei-aerospace, i-nuclear, nokuzivikelaimisebenzi.

Ubuchwepheshe Bokukhiqiza

I-Sapphire optical fibers ngokuvamile ikhiqizwa kusetshenziswaI-Laser-Heated Pedestal Growth (LHPG) or I-Edge-defined Film-fed Growth (EFG)izindlela. Ngesikhathi sokukhula, ikristalu yembewu yesafire iyashiswa ukuze yakhe indawo encane encibilikisiwe bese idonselwa phezulu ngenani elilawulwayo ukuze yakhe i-fiber enobubanzi obufanayo kanye nokuma kwekristalu okuphelele.
Le nqubo iqeda imingcele yokusanhlamvu nokungcola, okuholela ekutheni aI-fiber ye-crystal eyodwa engenasici. Ingaphezulu libe selipholishwa kahle, lifakwe i-anneal, bese ligcotshwa ngokuzikhethelaizingqimba ezivikelayo noma ezikhanyayoukuthuthukisa ukusebenza nokuqina.

Izinkambu Zokusebenza

FAQ

I-Q1: Ihluke kanjani i-sapphire fiber kuma-quartz noma ama-chalcogenide fibers?
A: Isafire iyikristalu eyodwa, hhayi ingilazi ye-amorphous. Inephuzu lokuncibilika eliphakeme kakhulu, iwindi lokudlulisa elibanzi, nokumelana okuphakeme nokulimala kwemishini namakhemikhali.

Q2: Ingabe imicu yesafire ingagcotshwa?
A: Yebo. Izembatho zensimbi, ze-ceramic, noma ze-polymer zingasetshenziswa ukuze kuthuthukiswe ukuphatha, ukulawula ukubonakaliswa, nokumelana nemvelo.

Q3: Kuyini ukulahleka okujwayelekile kwefiber optical fiber?
A: I-Optical attenuation icishe ibe ngu-0.3–0.5 dB/cm ku-2–3 μm, kuye ngokupholisha kwendawo nobude begagasi.
