Wamkelekile kwi-Ruijie Laser

isebenza njani i-fiber laser?–uLisa ovela kumzi-mveliso wokusika i-fiber laser yaseRuijie

Ifiber esetyenziswa njengendawo esembindini yelaser yakho iya kuba ifakwe kwizinto ezinqabileyo zomhlaba, kwaye uya kufumanisa ukuba le yiErbium.Isizathu sokuba kwenziwe oku kungenxa yokuba amanqanaba e-athomu ezi zinto zomhlaba anamanqanaba aluncedo kakhulu, avumela ukuba kusetyenziswe umthombo wempompo yelaser yediode ngexabiso eliphantsi, kodwa oko kuseza kubonelela ngemveliso ephezulu yamandla.

Umzekelo, nge-doping fiber kwi-Erbium, inqanaba lamandla elikwazi ukufunxa iifotoni ezinobude obungamaza angama-980nm lubolelwe kwi-meta-stable elilingana ne-1550nm.Oku kuthetha ukuthini ukuba ungasebenzisa umthombo wempompo ye-laser kwi-980nm, kodwa ufikelele umgangatho ophezulu, amandla aphezulu kunye ne-laser yamandla aphezulu ye-1550nm.

Iiathom ze-Erbium zisebenza njenge-laser medium kwi-doped fiber, kunye neefotoni ezikhutshiweyo zihlala ngaphakathi kwe-fiber core.Ukwenza umngxuma apho iifotoni zihlala zibambekile, into eyaziwa ngokuba yiFiber Bragg Grating yongezwa.

I-Bragg Grating licandelo nje leglasi elinemigca kuyo - kulapho ke isalathisi sokugqabhuka sitshintshiwe.Naliphi na ixesha ukukhanya kudlula umda phakathi kwesinye isalathiso se-refractive kunye nesilandelayo, ukukhanya okuncinci kuyabuyiselwa umva.Ngokusisiseko, iBragg Grating yenza i-fiber laser isebenze njengesipili.

I-laser yepompo igxile kwi-cladding ehlala ijikeleze i-fiber core, njengoko i-fiber core ngokwayo incinci kakhulu ukuba ibe ne-laser ye-diode ephantsi egxile kuyo.Ngokumpompa i-laser kwi-cladding ejikeleze umbindi, i-laser ibethelwa ngaphakathi, kwaye ngalo lonke ixesha idlula engundoqo, ngakumbi nangakumbi ukukhanya kwempompo kutsalwa ngundoqo.
