I-sapphire fiber single crystal Al₂O₃ high optical transmittance melting point 2072℃ ingasetyenziselwa izinto zefestile yelaser

Inkcazo emfutshane:

Ifayibha yesafire yenziwe nge-alumina yekristale enye (Al₂O₃), eyimpahla enamandla aphezulu oomatshini, ukumelana neekhemikhali kunye nokuqhuba kakuhle kobushushu. Isafire ikwisakhiwo sekristale esinama-hexagonal, uluhlu lokudluliselwa kokukhanya yi-0.146.0μm, kwaye inokudluliselwa okuphezulu kwe-optical kwibhendi ye-3.05.0μm. Indawo yokunyibilika kwesafire ifikelela kwi-2072 ° C, kwaye ubunzima bulandela idayimani kuphela, ngoko ke ifayibha yesafire inokumelana nobushushu okuphezulu kakhulu kunye namandla oomatshini.

Inkqubo yokulungiselela

1. Ifayibha yesafire idla ngokulungiswa ngendlela ye-laser heated base method (LHPG). Ngale ndlela, ifayibha yesafire ene-geometric axis kunye ne-C-axis ingakhuliswa, enokuhanjiswa okuhle kwi-infrared band ekufutshane. Ukulahleka ikakhulu kuvela ekuqhekekeni okubangelwa ziziphene zekristale ezikhoyo kumphezulu wefayibha okanye kumphezulu wayo.

2. Ukulungiswa kwefayibha yesafire egqunywe yisilika: Okokuqala, i-poly (dimethylsiloxane) coating ibekwa phezu komphezulu wefayibha yesafire ize icocwe, emva koko umaleko ogqunywe yisilika uguqulwa ube yisilika kwi-200 ~ 250℃ ukuze kufunyanwe ifayibha yesafire egqunywe yisilika. Le ndlela inobushushu obuphantsi benkqubo, ukusebenza okulula kunye nokusebenza kakuhle kwenkqubo.

3. Ukulungiswa kwefayibha yesafire cone: Isixhobo sokukhulisa indlela yokufudumeza yelaser sisetyenziselwa ukulungiselela ifayibha yesafire cone ngokulawula isantya sokuphakamisa ikristale yembewu yesafire fiber kunye nesantya sokondla intonga yomthombo wekristale yesafire. Le ndlela ingalungisa ifayibha yesafire cone enobukhulu obahlukeneyo kunye nesiphelo esincinci, esinokuhlangabezana neemfuno ezithile zesicelo.

Iintlobo zefayibha kunye neenkcukacha

1. Uluhlu lobubanzi: Ububanzi befayibha yesafire bunokukhethwa phakathi kwe-75 ~ 500μm ukuze buvumelane neemfuno ezahlukeneyo zokusetyenziswa.

2. Ifayibha yekhonikhi: Ifayibha yesafire ekhonikhi inokufikelela ekudlulisweni kwamandla okukhanya okuphezulu ngelixa iqinisekisa ukuguquguquka kwefayibha. Le fayibha iphucula ukusebenza kakuhle kokudluliselwa kwamandla ngaphandle kokunciphisa ukuguquguquka.

3. Ii-Bushings kunye nezihlanganisi: Kwiifayibha ze-optical ezinobubanzi obungaphezulu kwe-100μm, ungakhetha ukusebenzisa ii-bushings ze-polytetrafluoroethylene (PTFE) okanye izihlanganisi ze-optical fiber ukukhusela okanye ukuqhagamshela.

Intsimi yesicelo

1. I-sensor yefayibha yobushushu obuphezulu: I-sapphire fiber ngenxa yokumelana kwayo nobushushu obuphezulu, ukumelana nokugqwala kweekhemikhali, ifanelekile kakhulu ekuqondeni ifayibha kwindawo enobushushu obuphezulu. Umzekelo, kwi-metallurgy, kushishino lweekhemikhali, kunyango lobushushu nakwezinye iindawo, ii-sensor zefayibha yobushushu obuphezulu zesapphi zinokulinganisa ngokuchanekileyo ubushushu ukuya kuthi ga kwi-2000 ° C.

2. Ukudluliselwa kwamandla elaser: Iimpawu zokudluliselwa kwamandla aphezulu kwifayibha yesafire ziyenza isetyenziswe kakhulu kwicandelo lokudluliselwa kwamandla elaser. Ingasetyenziswa njengezinto zefestile zelaser ukumelana nemitha yelaser enamandla aphezulu kunye neendawo ezinobushushu obuphezulu.

3. Ukulinganisa ubushushu bemizi-mveliso: Kwicandelo lokulinganisa ubushushu bemizi-mveliso, izinzwa zobushushu obuphezulu zefayibha yesafire zinokubonelela ngedatha yokulinganisa ubushushu echanekileyo nezinzileyo, enceda ukujonga nokulawula utshintsho lobushushu kwinkqubo yemveliso.

4. Uphando lwezenzululwazi kunye nonyango: Kwicandelo lophando lwezenzululwazi kunye nonyango lwezonyango, ifayibha yesafire ikwasetyenziswa kwiindlela ezahlukeneyo zokulinganisa nokuvavanya ukukhanya okuchanekileyo ngenxa yeempawu zayo ezizodwa zomzimba nezekhemikhali.
