Siyakwamukela ku-Ruijie Laser

isebenza kanjani i-fiber laser?–ULisa wase-Ruijie fibre laser cutting factory

I-fiber esetshenziswa njengendawo emaphakathi ye-laser yakho izobe ifakwe ezintweni zomhlaba eziyivelakancane, futhi ngokuvamile uzothola ukuthi lena i-Erbium.Isizathu sokuthi lokhu kwenziwe ingoba amazinga e-athomu alezi zakhi zomhlaba anamazinga wamandla asebenziseka kakhulu, avumela ukuthi kusetshenziswe umthombo wephampu welaser we-diode oshibhile, kodwa lokho kusazonikeza amandla aphezulu.

Isibonelo, nge-doping fiber ku-Erbium, izinga lamandla elikwazi ukumunca ama-photon anobude begagasi obungu-980nm libole libe ku-meta-stable elilingana no-1550nm.Okushiwo lokhu ukuthi ungasebenzisa umthombo wephampu ye-laser ku-980nm, kodwa uzuze ikhwalithi ephezulu, amandla aphezulu kanye ne-laser enamandla aphezulu engu-1550nm.

Ama-athomu e-Erbium asebenza njenge-laser medium ku-doped fiber, futhi ama-photon akhishwayo ahlala ngaphakathi kwe-fiber core.Ukuze udale imbobo lapho ama-photon ehlala ebambekile, into eyaziwa ngokuthi i-Fiber Bragg Grating iyengezwa.

I-Bragg Grating imane iyingxenye yengilazi enemigqa kuyo - okuyindawo lapho inkomba ye-refractive ishintshiwe khona.Noma nini lapho ukukhanya kudlula umngcele phakathi kwenkomba eyodwa ye-refractive kanye nelandelayo, ukukhanya okuncane kuyaphindiselwa emuva.Empeleni, i-Bragg Grating yenza i-fiber laser isebenze njengesibuko.

I-laser yephampu igxile ekuhlanganisweni okuhlala eduze kwe-fiber core, njengoba i-fiber core ngokwayo incane kakhulu ukuthi ibe ne-laser diode yekhwalithi ephansi egxile kuyo.Ngokumpompa i-laser ekuhlanganisweni okuzungeze umgogodla, i-laser ibhampa ngaphakathi, futhi ngaso sonke isikhathi lapho idlula umgogodla, ukukhanya kwepompo kudonswa umongo.
