I-Fiber Fiber single crystal Al₂O₃ high optical transmittance melting point 2072℃ ingasetshenziswa ezintweni zefasitela le-laser

I-fibre yesafire crystal eyodwa I-Al₂O₃ iphuzu lokuncibilika kokudlulisa okuphezulu kwe-optical 2072℃ ingasetshenziswa ezintweni zefasitela le-laser Isithombe Esifakiwe

Incazelo emfushane:

I-fibre yesafire yenziwe nge-alumina yekristalu eyodwa (Al₂O₃), okuyizinto ezinamandla aphezulu okusebenza ngomshini, ukumelana namakhemikhali kanye nokushisa okuhle. I-safire ingeyesakhiwo sekristalu esinezinhlangothi eziyisithupha, ububanzi bokudlulisa ukukhanya bungu-0.146.0μm, futhi inokudlulisa okuphezulu kokukhanya ebhendini engu-3.05.0μm. Indawo yokuncibilika kwesafire ifinyelela ku-2072 ° C, futhi ubulukhuni bulandela idayimane kuphela, ngakho-ke i-fibre yesafire inokumelana nokushisa okuphezulu kakhulu kanye namandla okusebenza ngomshini.

Inqubo yokulungiselela

1. I-fibre yesafire ivame ukulungiswa ngendlela yesisekelo esishisayo se-laser (LHPG). Ngale ndlela, i-fibre yesafire ene-axis yejiyomethri kanye ne-C-axis ingakhuliswa, enokudluliselwa okuhle eduze kwe-infrared band. Ukulahleka kuvela kakhulu ekuhlakazekeni okubangelwa amaphutha ekristalu akhona noma ebusweni be-fibre.

2. Ukulungiswa kwe-silica clad sapphire fiber: Okokuqala, i-poly (dimethylsiloxane) coating ibekwa phezu kwe-sapphire fiber bese iqiniswa, bese ungqimba oluqiniswayo luguqulwa lube yi-silica ku-200 ~ 250℃ ukuthola i-silica clad sapphire fiber. Le ndlela inokushisa okuphansi kwenqubo, ukusebenza okulula kanye nokusebenza kahle kwenqubo ephezulu.

3. Ukulungiswa kwefayibha yekhoni yesafire: Idivayisi yokukhulisa indlela yokushisa ye-laser isetshenziselwa ukulungisa ifayibha yekhoni yesafire ngokulawula isivinini sokuphakamisa sekristalu yembewu yesafire kanye nesivinini sokudla senduku yomthombo wekristalu yesafire. Le ndlela ingalungisa ifayibha yekhoni yesafire enobukhulu obuhlukile kanye nesiphelo esihle, esingahlangabezana nezidingo ezithile zohlelo lokusebenza.

Izinhlobo zefayibha kanye nemininingwane

1. Ububanzi be-diameter: Ububanzi be-fibre ye-sapphire bungakhethwa phakathi kuka-75 ~ 500μm ukuze buvumelane nezidingo ezahlukene zohlelo lokusebenza.

2. I-fibre eyi-conical: I-fibre ye-sapphire eyi-conical ingafinyelela ukudluliselwa kwamandla okukhanya okuphezulu ngenkathi iqinisekisa ukuguquguquka kwe-fibre. Le fibre ithuthukisa ukusebenza kahle kokudluliselwa kwamandla ngaphandle kokulahlekelwa ukuguquguquka.

3. Ama-bushings kanye nezixhumi: Kuma-optical fibers anobubanzi obungaphezu kuka-100μm, ungakhetha ukusebenzisa ama-bushings e-polytetrafluoroethylene (PTFE) noma izixhumi ze-optical fiber ukuze uvikele noma uxhume.

Inkambu yohlelo lokusebenza

1. Inzwa yefayibha yokushisa okuphezulu: Ifayibha yesafire ngenxa yokumelana kwayo nokushisa okuphezulu, ukumelana nokugqwala kwamakhemikhali, ifaneleka kakhulu ukuzwa ifayibha endaweni yokushisa okuphezulu. Isibonelo, kwezensimbi, embonini yamakhemikhali, ekwelashweni kokushisa nakwezinye izinkambu, izinzwa zefayibha yesafire zingalinganisa amazinga okushisa afinyelela ku-2000 ° C ngokunembile.

2. Ukudluliswa kwamandla e-laser: Izici zokudluliselwa kwamandla aphezulu kwe-sapphire fiber zenza isetshenziswe kabanzi emkhakheni wokudluliswa kwamandla e-laser. Ingasetshenziswa njengezinto zefasitela zama-laser ukumelana nemisebe ye-laser enamandla aphezulu kanye nezimo zokushisa okuphezulu.

3. Ukulinganisa izinga lokushisa kwezimboni: Emkhakheni wokulinganisa izinga lokushisa kwezimboni, izinzwa zokushisa okuphezulu ze-sapphire fiber zinganikeza idatha yokulinganisa izinga lokushisa enembile nezinzile, okusiza ukuqapha nokulawula izinguquko zokushisa enqubweni yokukhiqiza.

4. Ucwaningo lwesayensi kanye nezokwelapha: Emkhakheni wocwaningo lwesayensi kanye nokwelashwa kwezokwelapha, i-sapphire fiber isetshenziswa futhi ezinhlotsheni ezahlukene zokulinganisa okunembile kanye nezicelo zokuzwa ngenxa yezakhiwo zayo eziyingqayizivele zomzimba nezamakhemikhali.

Ngokwezidingo ezithile zamakhasimende, i-XKH inikeza izinsizakalo zokuklama ngokwezifiso ze-sapphire fiber ezenziwe ngokwezifiso. Kungakhathaliseki ukuthi ubude nobubanzi be-fiber, noma izidingo zokusebenza okukhethekile kwe-optical, i-XKH inganikeza amakhasimende ikhambi elingcono kakhulu lokuhlangabezana nezidingo zabo zohlelo lokusebenza ngokuklama nokubala kobungcweti. I-XKH inobuchwepheshe obuthuthukisiwe bokukhiqiza i-sapphire fiber, okuhlanganisa indlela yesisekelo esishisayo se-laser (LHPG), ukukhiqiza i-sapphire fiber esezingeni eliphezulu, esebenza kahle kakhulu. I-XKH ilawula ngokuqinile yonke isixhumanisi enkambisweni yokukhiqiza ukuqinisekisa ukuthi ikhwalithi yomkhiqizo nokusebenza kuhlangabezana nokulindelwe ngamakhasimende.
