I-Sapphire fiber single crystal Al₂O₃ high optical transmittance melting point 2072℃ ingasetshenziselwa izinto zewindi le-laser

Incazelo emfushane:

I-Sapphire fiber yenziwe nge-crystal alumina eyodwa (i-Al₂O₃), okuyimpahla enamandla amakhulu emishini, ukumelana namakhemikhali kanye nokuhamba kahle kwe-thermal. Isafire ingeyesakhiwo sekristalu esinezinhlangothi ezine, ububanzi bokudluliswa kokukhanya ngu-0.146.0μm, futhi inokudlulisa amehlo okuphezulu ebhendini engu-3.05.0μm. Iphuzu lokuncibilika lesafire liphezulu njengo-2072 ° C, futhi ubulukhuni bungokwesibili ngemva kwedayimane, ngakho-ke i-sapphire fiber inokumelana nokushisa okuphezulu kakhulu namandla okusebenza.

Inqubo yokulungiselela

1. I-Sapphire fiber ivamise ukulungiselelwa nge-laser heated base method (LHPG). Ngale ndlela, i-sapphire fiber ene-geometric axis kanye ne-C-axis ingakhuliswa, enokudlulisa okuhle eduze nebhendi ye-infrared. Ukulahlekelwa ikakhulukazi kuvela ekuhlakazeni okubangelwa ukukhubazeka kwekristalu okukhona ngaphakathi noma ngaphezulu kwefayibha.

2. Ukulungiswa kwe-silica clad sapphire fiber: Okokuqala, i-poly (dimethylsiloxane) i-coating isethwe ebusweni be-sapphire fiber futhi iphulukisiwe, bese ungqimba oluphulukisiwe luguqulwa lube yi-silica ku-200 ~ 250℃ ukuze kutholwe i-silica clad sapphire fiber. Le ndlela inezinga lokushisa eliphansi lenqubo, ukusebenza okulula kanye nokusebenza kahle kwenqubo.

3.Ukulungiswa kwe-sapphire cone fiber: Ithuluzi lokukhula le-laser heat base method lisetshenziselwa ukulungisa i-sapphire cone fibre ngokulawula isivinini sokuphakamisa sekristalu yezinhlamvu zesafire fiber kanye nesivinini sokuphakela se-sapphire crystal source rod. Le ndlela ingalungisa isafire conical fiber enogqinsi oluhlukene kanye nesiphetho esihle, esingahlangabezana nezidingo ezithile zohlelo lokusebenza.

Izinhlobo ze-fiber kanye nokucaciswa

I-1.Ububanzi be-Diameter: Ububanzi be-sapphire fiber bungakhethwa phakathi kuka-75 ~ 500μm ukuze uvumelane nezidingo ezahlukene zohlelo lokusebenza.

2. I-conical fiber: I-conical sapphire fiber ingafinyelela ukudluliswa kwamandla okukhanya okuphezulu ngenkathi iqinisekisa ukuguquguquka kwefayibha. Le fibre ithuthukisa ukusebenza kahle kokudluliselwa kwamandla ngaphandle kokudela ukuguquguquka.

3. Izihlahla nezixhumi: Kumafayibha okubona anobubanzi obungaphezu kuka-100μm, ungakhetha ukusebenzisa izihlahla ze-polytetrafluoroethylene (PTFE) noma izixhumi zefiber optical ukuze uvikeleke noma uxhumeke.

Inkambu yohlelo lokusebenza

I-1.Inzwa ye-fiber yokushisa ephezulu: I-Sapphire fiber ngenxa yokumelana kwayo nokushisa okuphezulu, ukumelana nokugqwala kwamakhemikhali, ifaneleka kakhulu ukuzwa i-fiber endaweni yokushisa ephezulu. Isibonelo, ku-metallurgy, embonini yamakhemikhali, ekwelapheni ukushisa kanye neminye imikhakha, izinzwa zokushisa eziphakeme zesafire fiber zingakala ngokunembile amazinga okushisa aze afike ku-2000 ° C.

I-2.Ukudluliswa kwamandla nge-Laser: Izici eziphezulu zokudlulisa amandla e-sapphire fiber ziwenza asetshenziswe kabanzi emkhakheni wokudlulisa amandla we-laser. Ingasetshenziswa njengefasitela lezinto ze-lasers ukuze zimelane nemisebe ye-laser enamandla kakhulu kanye nezindawo zokushisa eziphezulu.

I-3.Isilinganiso sokushisa kwezimboni: Emkhakheni wokulinganisa izinga lokushisa kwezimboni, izinzwa ze-sapphire fiber high lokushisa zinganikeza idatha enembile futhi ezinzile yokulinganisa izinga lokushisa, esiza ukuqapha nokulawula izinguquko zokushisa kwinqubo yokukhiqiza.

4. Ucwaningo lwesayensi nezokwelapha: Emkhakheni wocwaningo lwesayensi nokwelashwa, i-sapphire fiber iphinde isetshenziswe ekulinganisweni okunembayo okuphezulu kwe-optical kanye nezicelo zokuzwa ngenxa yezakhiwo zayo ezihlukile zomzimba namakhemikhali.

Ngokwezidingo ezithile zamakhasimende, i-XKH ihlinzeka ngezinsizakalo zokuklama ngokwezifiso zefiber yesafire. Kungakhathaliseki ukuthi ubude nobubanzi befayibha, noma izimfuneko ezikhethekile zokusebenza kokubona, i-XKH inganikeza amakhasimende isixazululo esingcono kakhulu sokuhlangabezana nezidingo zawo zohlelo lokusebenza ngomklamo wochwepheshe nokubala. I-XKH inobuchwepheshe obuphambili bokukhiqiza i-sapphire fibre, okuhlanganisa indlela ye-laser heated base method (LHPG), ukukhiqiza ikhwalithi ephezulu, ukusebenza okuphezulu kwe-sapphire fiber. I-XKH ilawula ngokuqinile zonke izixhumanisi zenqubo yokukhiqiza ukuze kuqinisekiswe ukuthi ikhwalithi yomkhiqizo nokusebenza kuhlangabezana nokulindelwe ngamakhasimende.
