I-Fiber lasers kwintsimi yonxibelelwano lwefiber optical

IIFayibha Laseribhekisa kwilaser esebenzisa iintsinga zeglasi ezinqabileyo zomhlaba njengesixhobo sokuzuza. I-Fiber lasers inokuphuhliswa ngokusekwe kwi-fiber amplifiers, kwaye umgaqo wabo wokusebenza ngulo: thatha i-laser yefiber empompelwe ixesha elide njengomzekelo. Inxalenye yefiber efakwe kwi-ion yentsimbi enqabileyo yomhlaba ibekwe phakathi kwezibuko ezibini kunye ne-reflection ekhethiweyo. Isibane sempompo sidibanisa ifayibha ukusuka kwisipili sasekhohlo. Isibuko sasekhohlo sihambisa konke ukukhanya kwempompo kwaye sibonisa i-laser ngokupheleleyo, ukuze kusetyenziswe ngokufanelekileyo ukukhanya kwempompo kwaye kuthintele ukukhanya kwempompo ekukhanyeni kwaye kubangele ukukhanya okungazinzanga. I-endoscope efanelekileyo ivumela inxalenye ye-laser ukuba idlule ukuze yenze ingxelo ye-laser beam kwaye ifumane i-laser output. Iifotoni kumgama wempompo zifunxwa liphakathi, zenza uguqulo lwenombolo ye-ion, kwaye ekugqibeleni zivelise ukukhutshwa okuvuselelweyo kwi-doped fiber medium ukuya kwi-laser ephumayo.

Iimpawu ze-fiber lasers: Ukusebenza okuphezulu kokudibanisa kuba i-laser medium ngokwayo yeyona ndawo iphakathi. Ukusebenza okuphezulu kokuguqulwa, umda ophantsi kunye nefuthe elihle lokutshatyalaliswa kobushushu; Inoluhlu olubanzi lolungelelwaniso, ukusasazwa kakuhle kunye nokuzinza. Iilaser zeFiber nazo zinokuqondwa njengesiguquli sobude obusebenzayo, oko kukuthi, ukuguqula ubude bamaza okukhanya kwempompo bube kubude bobude bee-ions zomhlaba ezinqabileyo. Le wavelength ehlalayo ichanekileyo yimveliso yokukhanya kwe-laser fiber. Ayilawulwa yimpompo yempompo kwaye inqunywe kuphela yizinto ezinqabileyo zedoping zomhlaba kwizinto eziphathekayo. Ke ngoko, iisemiconductor lasers zobude obufutshane obuhlukeneyo kunye namandla aphezulu ahambelana nembonakalo yokufunxa yeeyoni zomhlaba ezinqabileyo zinokusetyenziswa njengemithombo yempompo ukufumana iziphumo zelaser zobude obahlukeneyo.

Ukuhlelwa kweFiber laser: Kukho iintlobo ezininzi zefiber lasers. Ngokwendlela yokufumana inzuzo, zinokuhlelwa njengezi: iilaser zefiber ezinqabileyo zomhlaba, iilaser zefiber ezingenayo i-fiber lasers, i-crystal fiber lasers enye, kunye ne-laser fiber lasers. Ngokwesakhiwo sefayibha, zinokuhlelwa zibe: iilaser zefiber ezine-lad-clad kunye ne-laser-clad fiber lasers. Ngokwezinto ezifakwe kwi-doped, zinokuthi zihlelwe kwiintlobo ezingaphezu kweshumi ezifana ne-erbium, neodymium, praseodymium, njl. Ngokwendlela yokumpompa, ingahlelwa njenge: i-fiber optical end face pumping, i-micro prism side optical coupling pumping, i-ring pumping, njl iilaser, “8″ iilaser ezimilise okwecango, njl.njl. Ngokwemowudi yokusebenza, zinokuhlelwa njenge: pulsed optical fiber kunye nelaser eqhubekayo, njl. njl.iilaser ezinamandla aphezulu, I-laser ye-ultrashort pulse, kwayeiilaser ezinobubanzi obumxinwazivela enye emva kwenye. Okulandelayo, iilaser zefiber ziya kuqhubeka zikhula kumkhombandlela wamandla aphezulu aphumayo, umgangatho ongcono we-beam, kunye nencopho yepulse ephezulu.
