I-Fiber lasers emkhakheni wokuxhumana kwe-fiber optical

II-Fiber Laserisho i-laser esebenzisa imicu yengilazi eyenziwe nge-earth engavamile njengendlela yokuzuza. Ama-laser we-fiber angathuthukiswa ngokusekelwe kuma-amplifiers e-fiber, futhi umgomo wawo wokusebenza uthi: thatha i-laser ye-fiber edonsa ubude njengesibonelo. Ingxenye yefayibha ehlanganiswe nama-ion ensimbi yomhlaba ayivelakancane ibekwe phakathi kwezibuko ezimbili ezinokukhanya okukhethiwe. Ukukhanya kwepompo kuhlangana ku-fiber kusuka esibukweni esingakwesokunxele. Isibuko esingakwesokunxele sidlulisa konke ukukhanya kwepompo futhi sibonisa i-laser ngokuphelele, ukuze kusetshenziswe kahle ukukhanya kwepompo futhi kuvimbele ukukhanya kwepompo ukuthi kungasaniki futhi kubangele ukukhanya okuphumayo okungazinzile. I-endoscope engakwesokudla ivumela ingxenye ye-laser ukuthi idlule ukuze yakhe impendulo ye-laser beam futhi ithole okukhipha i-laser. Ama-photons kubude be-wavelength bephampu amuncwa okuphakathi, akha ukuguqulwa kwenombolo ye-ion, futhi ekugcineni akhiqize ukukhishwa okukhuthazwayo ku-doped fiber medium kuya ku-laser ephumayo.

Izici ze-fiber lasers: Ukusebenza kahle okuphezulu kokuxhumana ngoba i-laser medium ngokwayo iyi-waveguide medium. Ukusebenza kahle kokuguqulwa okuphezulu, umkhawulo ophansi kanye nomphumela omuhle wokushisa ukushisa; Inohlu olubanzi lokudidiyela, ukuhlakazeka okuhle nokuzinza. Ama-laser we-fiber angaphinda aqondwe njengesiguquli se-wavelength esisebenzayo, okungukuthi, ukuguqula ubude begagasi bokukhanya kwephampu bube ubude beza beza obungama-ion bomhlaba obuyivelakancane. Le wavelength ehlala njalo iwubude bokukhanya obuphumayo be-fiber laser. Ayilawulwa ubude begagasi bepompo futhi inqunywa kuphela izakhi ze-doping zomhlaba ezingavamile kundaba. Ngakho-ke, ama-lases we-semiconductor ama-wavelengths amafushane ahlukene namandla aphezulu ahambisana nokubukwa kokumuncwa kwama-ion omhlaba angavamile angasetshenziswa njengemithombo yephampu ukuze kutholwe ukuphuma kwe-laser kwamaza ahlukene.

Ukuhlukaniswa kwe-fiber laser: Kunezinhlobo eziningi ze-fiber lasers. Ngokusho kwendlela yokuthola, zingahlukaniswa ngokuthi: amalaser efiber doped fiber, amalaser efiber angaqondile, ama-laser fiber single crystal, namalaser epulasitiki. Ngokuya ngesakhiwo se-fiber, zingahlukaniswa zibe: ama-laser e-fiber egqoke eyodwa kanye nama-laser fiber agqoke kabili. Ngokusho kwezakhi ezihlanganisiwe, zingahlukaniswa zibe izinhlobo ezingaphezu kweshumi ezifana ne-erbium, neodymium, praseodymium, njll. Ngokwendlela yokumpompa, ingahlukaniswa ngokuthi: i-fiber optical end face pumping, i-micro prism side optical coupling pumping, ukupompa indandatho, njll Ngokusho kwesakhiwo se-fiber cavity, i-fiber classified laser can be resonant cavity: ama-laser, “8″ ama-cavity lasers anomumo, njll. Ngokwemodi yokusebenza, angahlukaniswa ngokuthi: i-pulsed optical fiber kanye ne-continuous laser, njll. Ukuthuthukiswa kwama-fiber lasers kuyakhula ngesivinini.ama-laser aphezulu, ama-laser we-ultrashort pulse, futhiama-laser asebenzisekayo anobubanzi obuncane bomugqaziphuma zilandelana. Okulandelayo, ama-laser e-fiber azoqhubeka nokuthuthuka eziqondisweni zamandla aphezulu okukhiphayo, ikhwalithi engcono ye-beam, neziqongo ze-pulse ephakeme.
