Lazeri ya fibre murwego rwo gutumanaho kwa fibre optique

UwitekaFibre Laserbivuga lazeri ikoresha isi idasanzwe-yuzuye ibirahuri bya fibre nkibintu byunguka. Lazeri ya fibre irashobora gutezwa imbere ishingiye kuri fibre amplibre, kandi ihame ryakazi ryayo ni: fata urugero rwa fibre fibre ndende. Igice cya fibre ikozwe hamwe nubutaka bwicyuma cya ion gishyirwa hagati yindorerwamo ebyiri zifite icyerekezo cyatoranijwe. Pompe yoroheje ihuza fibre kuva mumirorerwamo yibumoso. Indorerwamo y'ibumoso yohereza urumuri rwa pompe kandi ikagaragaza lazeri rwose, kugirango ukoreshe neza urumuri rwa pompe kandi urinde urumuri rwa pompe kumvikana kandi rutere urumuri rudahinduka. Endoscope iburyo yemerera igice cya laser kunyuramo kugirango habeho ibitekerezo byurumuri rwa laser no kubona ibisohoka bya laser. Fotone kuri pompe yumurambararo ikururwa nuburyo bugezweho, ikora ion inversion, hanyuma amaherezo ikabyara imyuka ihumanya mumyuka ya fibre ikoreshwa kugirango isohore laser.

Ibiranga fibre ya fibre: Gukora neza cyane kuko laser igikoresho ubwacyo nicyo cyerekezo cya waveguide. Ihinduka ryiza cyane, ntarengwa kandi ningaruka nziza zo gukwirakwiza; Ifite intera nini yo guhuza ibikorwa, gutatanya neza no gutuza. Lazeri ya fibre irashobora kandi kumvikana nkumuhinduzi mwiza woguhindura, ni ukuvuga guhindura uburebure bwumucyo wumucyo wa pompe muburebure bwumurambararo wubutaka bwa ion zidasanzwe. Ubu burebure bwa lasing nubusanzwe busohora urumuri rwumucyo wa fibre laser. Ntabwo igenzurwa nuburebure bwa pompe kandi igenwa gusa nubutaka budasanzwe bwa doping mubintu. Kubwibyo, semiconductor lazeri yuburebure butandukanye bwumurambararo nububasha buhanitse bujyanye no kwinjiza ibintu bidasanzwe bya ioni yisi irashobora gukoreshwa nkisoko ya pompe kugirango ibone umusaruro wa laser wuburebure butandukanye.

Ibyiciro bya fibre laser: Hariho ubwoko bwinshi bwa fibre lazeri. Ukurikije inyungu zunguka, zishobora gushyirwa mubikorwa nka: isi idasanzwe idasanzwe ya fibre lazeri, fibre fibre idafite umurongo, lazeri imwe ya kristal fibre, hamwe na plasitike ya fibre. Ukurikije imiterere ya fibre, irashobora gushyirwa mubice: fibre fibre imwe imwe hamwe na fibre fibre ebyiri. Ukurikije ibintu byahinduwe, birashobora gushyirwa mubwoko burenga icumi nka erbium, neodymium, praseodymium, nibindi. Ukurikije uburyo bwo kuvoma, bushobora gushyirwa mubikorwa nka: optique fibre end end pomping, micro prism side optique coupling pomping, pomping ring, nibindi. buryo, barashobora gushyirwa mubikorwa nka: pulsed optique fibre na laser ikomeza, nibindi. Iterambere rya fibre fibre irihutaamashanyarazi menshi, ultrashort pulse laseri, naGufunga-umurongo mugaribigenda bigaragara. Ibikurikira, fibre lasers izakomeza gutera imbere mubyerekezo byimbaraga zisohoka, ubwiza bwibiti byiza, hamwe nimpinga ndende.
