Murakaza neza kuri Ruijie Laser

Fibre optique ya fibre laser yo gukata ni ubwoko bwimikorere ya infrarafarike ya lazeri hamwe na fibre laser nkibikoresho bikora (kunguka hagati).Irashobora kugabanywa mubutaka budasanzwe doped fibre laser, optique fibre idafite umurongo wa lazeri, lazeri imwe ya kristal fibre laser, fibre arc laser, nibindi..bishingiye kumyidagaduro yo gutangiza.Muri byo, isi idasanzwe idasanzwe ya fibre laseri irakuze cyane, nka dopi erbium fibre amplifier (EDFA) yakoreshejwe cyane muri sisitemu y'itumanaho rya fibre optique.Laser fibre ikoreshwa cyane mubisirikare (guhangana na fotoelectric guhangana, gutahura laser, itumanaho rya laser, nibindi), gutunganya lazeri (marike ya laser, robot ya laser, micromachining, nibindi), ubuvuzi nibindi bice.

Lazeri ya fibre ikorwa na SiO2 nkibikoresho bya matrix ya fibre ikomeye yibirahure, ihame ryo kuyobora urumuri ni ugukoresha ihame ryuzuye ryerekana umuyoboro, ni ukuvuga, iyo urumuri rusohotse muburyo bwa optique yubucucike bukabije. Indanganturo Kuri imwe mu ngirabuzimafatizo ntoya ifite inguni nini irenze inguni nini, ibitekerezo byose bizagaragara kandi urumuri rwibyabaye ruzagaragazwa rwose nubucucike bwa optique bwurwego rwo hejuru rwangirika.Iyo urumuri rusohotse muburyo bwa optique yubucucike (ni ukuvuga, indangagaciro yo kugabanya urumuri rwagati ni nini) kugeza kuri interineti ya optique sparse medium (ni ukuvuga, indangantego yumucyo iba nto hagati), urumuri rwose rugaragarira inyuma muburyo bwambere.Nta mucyo ushobora gucengera mu buryo bwa optique bufite urwego ruto rwo kwangirika .. Ubusanzwe fibre yambaye ubusa igizwe ahanini nikirahure cyo hejuru cyerekana ikirahure (diameter ya 4 ~ 62.5μm), icyerekezo gito gike cyane cyerekana silicon ikirahure cyambaye (diameter diameter 125μm) hamwe na resin yongeyeho imbaraga.Uburyo bwo gukwirakwiza fibre optique irashobora kugabanywa muburyo bumwe (SM) fibre na fibre-moderi nyinshi (MM).Ubwoko bumwe bwa fibre yibanze ya diameter, ya diameter ntoya (4 ~ 12μm) irashobora gukwirakwiza icyitegererezo kimwe cyumucyo kandi uburyo bwo gukwirakwiza ni buto.Multimode fibre yibanze ya diameter ifite umubyimba mwinshi (diameter irenga 50μm) irashobora gukwirakwiza uburyo butandukanye bwurumuri mugihe ikwirakwizwa rya intermodal ari nini.Ukurikije igipimo cyo gukwirakwiza kwangiritse, fibre optique irashobora kugabanywa mubice byerekana intambwe (SI) hamwe na fibre yo mu cyiciro (GI).

Fata isi idasanzwe idasanzwe ya fibre lazeri kurugero, ikomatanyirijwe hamwe nubutaka budasanzwe nkinyungu zunguka, fibre fibre yashyizwe hagati yindorerwamo ebyiri zigize umwobo wa resonant.Itara rya pompe ni impanuka kuva M1 muri fibre hanyuma ikabyara laser kuva M2.Iyo urumuri rwa pompe runyuze muri fibre, rwinjizwa na ion zidasanzwe zubutaka muri fibre kandi electron zishimiwe kurwego rwo hejuru rushimishije kugirango abaturage bahindure ibice.Ibice byahinduwe byimurwa bivuye murwego rwo hejuru rwingufu zubutaka muburyo bwimirasire kugirango bibyare laser.
