Optical fiber ea faeba laser ho itšeha mochini ke mofuta oa mahareng infrared band laser le faeba laser e le thepa ea ho sebetsa (ho fumana mahareng).E ka aroloa ka laser doped fiber laser, optical fiber nonlinear effect laser, single crystal fiber laser, fiber arc lasers, joalo-joalo.Har'a tsona, li-lasers tsa fiber tse sa tloaelehang tsa lefats'e li holile haholo, joalo ka doped erbium fiber amplifier (EDFA) e sebelisitsoe haholo lits'ebetsong tsa puisano tsa optical fiber.Li-laser tsa fiber tse phahameng li sebelisoa haholo sesoleng (ho tobana le photoelectric, ho lemoha ka laser, puisano ea laser, joalo-joalo), ts'ebetso ea laser (ho tšoaea laser, roboto ea laser, laser micromachining, joalo-joalo), bongaka le likarolo tse ling.
Fiber laser e entsoe ke SiO2 e le thepa ea matrix ea khalase e tiileng ea fiber, e leng molao-motheo oa tataiso ea leseli ke ho sebelisa molao-motheo o feletseng oa ho bonahatsa tube, ke hore, ha leseli le ntšoa ho tloha ho optical density medium ea high refractive. index ho ea ho e 'ngoe ea li-index tse nyane tsa refractive tse nang le angle e kholoanyane ho feta angle ea bohlokoa, ho tla hlaha kakaretso ea setšoantšo 'me leseli la ketsahalo le tla bontšoa ka ho feletseng ho optical density medium ea high refractive index.Ha leseli le tsoa ho optical density medium (ke hore, index ea refractive ea leseli bohareng e kholo) ho ea ho sebopeho sa optical sparse medium (ke hore, index ea refractive ea leseli e nyane bohareng), leseli lohle le bonahatsoa morao ka har'a mokhoa oa pele.Ha ho khanya e ka phunyeletsang ka har'a "optical density medium" e nang le index e nyane ea refractive index.. Ordinary bare fiber hangata e entsoe ka "high refractive index glass core" (diameter ea 4 ~ 62.5μm) 125μm) le sekoaelo sa resin se matlafalitsoeng ka ho fetesisa.Fiber optic propagation mode e ka aroloa ka fiber ea mofuta o le mong (SM) le mefuta e mengata (MM) fiber.Mode o le mong oa fiber core bophara, oa bophara bo nyane ba mantlha (4 ~ 12μm) o ka hasanya mohlala o le mong oa leseli mme mokhoa oa ho hasana o nyane.Multimode fiber core diameter e teteaneng (diameter e kholo ho feta 50μm) e ka jala mefuta e fapaneng ea khanya ha phallo ea intermodal e le kholoanyane.Ho latela sekhahla sa kabo ea refractive, fiber ea optic e ka aroloa ka index ea mohato (SI) fiber le graded index (GI) fiber.
Nka li-lasers tse sa tloaelehang tsa lefats'e ka mohlala, tse nang le likaroloana tse sa tloaelehang tsa lefats'e e le mokhoa oa ho fumana chelete, likhoele tsa doped li tsitsitse pakeng tsa liipone tse peli tse etsang sekoti sa resonant.Leseli la pompo ke ketsahalo e tsoang ho M1 ho ea ho fiber ebe e hlahisa laser ho tloha M2.Ha leseli la pompo le feta ka har'a fiber, le kenngoa ke li-ion tse sa tloaelehang tsa lefats'e ka har'a fiber 'me li-elektronike li thabela boemo bo phahameng ba ho tsosoa ho finyella palo ea batho ba fetohang likaroloana.Likaroloana tse khelohileng li fetisoa ho tloha boemong bo phahameng ba matla ho ea sebakeng sa fatše ka mokhoa oa mahlaseli ho hlahisa laser.
