Laser na fiber a fannin sadarwa na fiber optic

TheLaser ɗin fiberYana nufin laser wanda ke amfani da zare-zare na gilashi mai ƙamshi a matsayin matsakaiciyar riba. Ana iya ƙirƙirar laser ɗin fiber bisa ga amplifiers na fiber, kuma ƙa'idar aikinsu ita ce: ɗauki laser ɗin fiber mai tsayi a matsayin misali. An sanya wani ɓangare na zare da aka haɗa da ions na ƙarfe na ƙasa mai ƙamshi tsakanin madubai biyu tare da zaɓin haske. Hasken famfo yana haɗuwa cikin zare daga madubin hagu. Madubin hagu yana watsa dukkan hasken famfo kuma yana nuna laser gaba ɗaya, don amfani da hasken famfo yadda ya kamata da kuma hana hasken famfo yin resonating da haifar da rashin daidaituwar hasken fitarwa. Endoscope na dama yana bawa ɓangaren laser damar wucewa don samar da martanin hasken laser da kuma samun fitowar laser. Ana ɗaukar photons a tsawon famfo ta hanyar matsakaici, suna samar da juyawar lambar ion, kuma a ƙarshe suna haifar da hayaki mai motsawa a cikin matsakaicin zare da aka ɗora zuwa laser fitarwa.

Halaye na laser ɗin fiber: Ingantaccen haɗin kai saboda matsakaiciyar laser kanta ita ce matsakaiciyar jagorar waveguide. Ingantaccen aiki mai yawa, ƙarancin iyaka da kyakkyawan tasirin watsa zafi; Yana da kewayon daidaitawa mai faɗi, watsawa mai kyau da kwanciyar hankali. Hakanan ana iya fahimtar laser ɗin fiber a matsayin mai canza tsawon tsayi mai inganci, wato, canza tsawon hasken famfo zuwa tsawon tsayi na ions na ƙasa mai ƙarancin doped. Wannan tsawon tsayi shine ainihin tsawon hasken fitarwa na laser ɗin fiber. Ba a sarrafa shi ta hanyar tsawon famfo kuma ana ƙaddara shi ne kawai ta hanyar abubuwan doping na ƙasa masu ƙarancin doping a cikin kayan. Saboda haka, lasers na semiconductor na gajerun tsayi daban-daban da babban ƙarfi wanda ya dace da yanayin sha na ions na ƙasa mai ƙarancin dogaye za a iya amfani da su azaman tushen famfo don samun fitowar laser na tsawon tsayi daban-daban.

Rarraba Laser ɗin Fiber: Akwai nau'ikan lasers da yawa na fiber. Dangane da yanayin samun riba, ana iya rarraba su kamar haka: lasers ɗin fiber mai rare earth doped, lasers ɗin fiber masu tasirin rashin layi, lasers ɗin fiber crystal guda ɗaya, da lasers ɗin fiber na filastik. Dangane da tsarin fiber, ana iya rarraba su zuwa: lasers ɗin fiber mai rufi ɗaya da lasers ɗin fiber mai rufi biyu. Dangane da abubuwan da aka yi amfani da su, ana iya rarraba su zuwa nau'ikan sama da goma kamar erbium, neodymium, praseodymium, da sauransu. Dangane da hanyar famfo, ana iya rarraba su zuwa: famfo fuska na fiber na gani, famfo na gefen micro prism na gani, famfo na zobe, da sauransu. Dangane da tsarin ramin resonant, ana iya rarraba su zuwa: lasers ɗin fiber na ramin FP, lasers ɗin fiber na ramin annular, lasers ɗin rami mai siffar "8″", da sauransu. Dangane da yanayin aiki, ana iya rarraba su zuwa: fiber na gani mai pulsed da laser mai ci gaba, da sauransu. Ci gaban lasers ɗin fiber yana hanzarta. A halin yanzu, nau'ikan daban-dabanlasers masu ƙarfi, na'urorin laser masu gajeru, kumalasers masu faɗi mai faɗi mai faɗiAna samun ci gaba ɗaya bayan ɗaya. Na gaba, za a ci gaba da haɓaka na'urorin laser na fiber ta hanyar amfani da ƙarfin fitarwa mafi girma, ingantaccen ingancin hasken rana, da kuma mafi girman kololuwar bugun jini.
