Fiber lasers mu rwego rwo gutumanaho kuri fibre optique

ItsindaFiber Laseryerekeza kuri lazeri ikoresha imigozi y'ibirahure idakunze gukoreshwa nk'uburyo bwo gukuramo umusaruro. Lazeri za fibre zishobora gukorwa hashingiwe ku byuma bitanga ingufu za fibre, kandi ihame ryabyo ni iri: fata urugero rwa lazeri ya fibre ikoreshwa mu kuyungurura uburebure. Igice cya fibre gishyizwemo iyoni z'icyuma zidakunze gukoreshwa gishyirwa hagati y'indorerwamo ebyiri zifite ubushobozi bwo kugarura urumuri. Urumuri rwa pompe ruhuza na fibre ivuye mu ndorerwamo y'ibumoso. Indorerwamo y'ibumoso yohereza urumuri rwose rwa pompe kandi ikagaragaza lazeri burundu, kugira ngo ikoreshe neza urumuri rwa pompe kandi ikumire urumuri rwa pompe kurusa no gutera urumuri rudahindagurika. Endoscope y'iburyo yemerera igice cya lazeri kunyuramo kugira ngo ikore igisubizo cy'imirasire ya laser kandi ibone umusaruro wa laser. Fotoni ziri ku bunini bwa pompe zitwarwa n'uburyo, zigakora ihindagurika rya ion number, hanyuma amaherezo zigatanga imyuka ishyushye mu buryo bwa fibre idakunze gukoreshwa ijya mu buryo bwa laser.

Ibiranga fibre lasers: Ikorana neza cyane kuko laser medium ubwayo ari yo iyobora umuraba. Ikorana neza cyane, ifite ubushobozi bwo gukwirakwiza ubushyuhe buke kandi ifite ingaruka nziza zo gukwirakwiza ubushyuhe; Ifite urwego rugari rwo guhuza, ikwirakwira neza kandi ihamye. Fiber lasers ishobora kandi kumvikana nk'ihindura uburebure bw'umuraba, ni ukuvuga guhindura uburebure bw'umuraba w'urumuri rwa pompe mu uburebure buto bw'iyoni za rare earth zadoped. Ubu uburebure buto bw'umuraba ni bwo uburebure bw'umuraba w'urumuri rwa fibre laser. Ntabwo igenzurwa n'uburebure bw'umuraba wa pompe kandi igenwa gusa n'ibintu bya rare earth doping biri mu bikoresho. Kubwibyo, semiconductor lasers z'uburebure buto butandukanye n'imbaraga nyinshi zijyanye na spectra ya rare earth ions zishobora gukoreshwa nk'isoko rya pompe kugira ngo haboneke umusaruro wa laser w'uburebure butandukanye.

Ishyirwa mu byiciro rya Fiber laser: Hari ubwoko bwinshi bwa fiber laser. Dukurikije uburyo bwo gukuramo, zishobora gushyirwa mu byiciro bikurikira: rare earth doped fiber lasers, nonlinear effect fiber lasers, single crystal fiber lasers, na plastic fiber lasers. Dukurikije imiterere ya fibre, zishobora gushyirwa mu byiciro bikurikira: single-clad fiber lasers na double-clad fiber lasers. Dukurikije ibintu bya doped, zishobora gushyirwa mu byiciro birenga icumi nka erbium, neodymium, praseodymium, nibindi. Dukurikije uburyo bwo kuvoma, zishobora gushyirwa mu byiciro bikurikira: optical fiber end face pumping, micro prism side optical coupling pumping, ring pumping, nibindi. Dukurikije imiterere ya resonant cavity, zishobora gushyirwa mu byiciro bikurikira: FP cavity fiber lasers, annular cavity fiber lasers, "8″ cavity lasers, nibindi. Dukurikije uburyo bwo gukora, zishobora gushyirwa mu byiciro bikurikira: pulsed optical fiber na continuous laser, nibindi. Iterambere rya fiber lasers riri kwihuta. Muri iki gihe, bitandukanyelaser zifite imbaraga nyinshi, lasers zo mu bwoko bwa pulse ngufi cyane, nalasers zishobora guhindurwa zifite ubugari bw'umurongo mutozirimo kugaragara imwe nyuma y’indi. Hanyuma, fibre lasers zizakomeza gutera imbere mu cyerekezo cy’imbaraga zo gutanga umusaruro mwinshi, ubwiza bw’imirasire, n’imbaraga zo gukanda cyane.
