Isafire yesafire enye ikristale Al₂O₃ iqondo eliphezulu lokunyibilikisa i-optical transmittance point 2072℃ ingasetyenziselwa imathiriyeli yefestile yelaser

Inkcazelo emfutshane:

I-Sapphire fiber yenziwe nge-crystal alumina eyodwa (i-Al₂O₃), eyona nto inamandla amakhulu omatshini, ukuchasana kweekhemikhali kunye nokuhamba kakuhle kwe-thermal. I-Sapphire iyingxenye ye-crystal structure ye-hexagonal, i-light transmission range yi-0.146.0μm, kwaye ine-optical transmittance ephezulu kwi-3.05.0μm band. Indawo yokunyibilika yesafire iphezulu ukuya kuthi ga kwi-2072 ° C, kwaye ukuqina kukwisibini kuphela kwidayimane, ngoko ke ifayibha yesafire inokumelana nobushushu obuphezulu kakhulu kunye namandla omatshini.

Iimbonakalo

Inkqubo yokulungiselela

1. I-Sapphire fiber idla ngokulungiswa nge-laser heated base method (LHPG). Ngale ndlela, ifayibha yesafire ene-geometric axis kunye ne-C-axis inokukhuliswa, enokuhanjiswa okulungileyo kufutshane nebhendi ye-infrared. Ilahleko ikakhulu ivela ekusasazekeni okubangelwa ziziphene zekristale ezikhoyo ngaphakathi okanye kumphezulu wefiber.

2. Ukulungiswa kwe-silica clad sapphire fiber: Okokuqala, i-poly (dimethylsiloxane) i-coating ibekwe phezu kwe-fiber ye-sapphire kwaye iphiliswe, kwaye emva koko i-layer ephilisiweyo iguqulwa ibe yi-silica kwi-200 ~ 250℃ ukufumana i-silica clad sapphire fiber. Le ndlela inokushisa kwenkqubo ephantsi, ukusebenza okulula kunye nokusebenza kakuhle kwenkqubo.

3.Ukulungiswa kwefiber yefiber yefiber: Isixhobo sokukhulisa isiseko sokufudumeza kwelaser sisetyenziselwa ukulungisa isafire cone fiber ngokulawula isantya sokunyuswa kwesapphire fiber seed crystal kunye nesantya sokutya sesafire crystal source rod. Le ndlela inokulungiselela i-fiber conical fiber enobunzima obuhlukeneyo kunye nesiphelo esihle, esinokuhlangabezana neemfuno ezithile zesicelo.

Iintlobo zeFayibha kunye neenkcukacha

I-1.Uluhlu lwe-Diameter: Ububanzi befiber yesafire bunokukhethwa phakathi kwe-75 ~ 500μm ukulungelelanisa kwiimfuno ezahlukeneyo zesicelo.

2. I-conical fiber: I-conical fiber fiber inokufezekisa ukuhanjiswa kwamandla okukhanya okuphezulu ngelixa iqinisekisa ukuguquguquka kwefayibha. Le fiber iphucula ukuhanjiswa kwamandla ngaphandle kokuncama ukuguquguquka.

3. I-Bushings kunye nezihlanganisi: Kwimicu ye-optical ene-diameter engaphezu kwe-100μm, unokukhetha ukusebenzisa i-polytetrafluoroethylene (PTFE) i-bushings okanye i-fiber optical connectors ukukhusela okanye ukudibanisa.

Indawo yosetyenziso

I-1.I-sensor ye-fiber yeqondo lokushisa eliphezulu: I-Sapphire fiber ngenxa yokumelana nokushisa okuphezulu, ukumelana neekhemikhali ze-corrosion, ifaneleke kakhulu kwi-fiber sensing kwindawo yokushisa ephezulu. Ngokomzekelo, kwi-metallurgy, kushishino lweekhemikhali, unyango lobushushu kunye nezinye iinkalo, i-sapphire fiber iqondo lobushushu obuphezulu bokwenza izinzwa ezinokulinganisa ngokuchanekileyo amaqondo obushushu ukuya kwi-2000 ° C.

I-2.Ukudluliselwa kwamandla eLaser: Iimpawu eziphezulu zokuhanjiswa kwamandla e-sapphire fiber zenza ukuba isetyenziswe ngokubanzi kwintsimi yokudluliselwa kwamandla e-laser. Ingasetyenziswa njengesixhobo sefestile ukuze i-laser imelane nemitha ye-laser ephezulu kunye nobushushu obuphezulu bendawo.

I-3.I-Industrial Industrial measurement: Kwintsimi yokulinganisa ukushisa kweshishini, i-sapphire fiber i-sensors yeqondo lokushisa eliphezulu inokubonelela ngedatha echanekileyo kunye nezinzile yokulinganisa ubushushu, okunceda ukubeka iliso nokulawula utshintsho lweqondo lokushisa kwinkqubo yokuvelisa.

4. Uphando lwezenzululwazi kunye nonyango: Kwinkalo yophando lwezenzululwazi kunye nonyango lwezonyango, i-sapphire fiber iphinda isetyenziswe kwiindidi ezahlukeneyo zokulinganisa okuchanekileyo okuphezulu kunye nezicelo zokuva ngenxa yeempawu zayo ezizodwa kunye neekhemikhali.
