ta yaya fiber Laser aiki?–Lisa daga Ruijie fiber Laser sabon factory
Za a yi amfani da fiber ɗin da ake amfani da shi azaman matsakaicin matsakaici don laser ɗin ku a cikin abubuwan da ba kasafai ba, kuma galibi za ku ga cewa wannan shine Erbium.Dalilin da ya sa ake yin haka shi ne saboda matakan zarra na waɗannan abubuwan duniya suna da matakan makamashi masu matuƙar amfani, wanda ke ba da damar yin amfani da tushen famfo laser diode mai rahusa, amma har yanzu hakan zai samar da babban makamashi.
Misali, ta hanyar doping fiber a cikin Erbium, matakin makamashi wanda zai iya ɗaukar photons tare da tsayin tsayin 980nm ya lalace zuwa meta-stable daidai da 1550nm.Abin da wannan ke nufi shi ne cewa za ka iya amfani da Laser famfo tushen a 980nm, amma har yanzu cimma wani high quality, high makamashi da kuma high ikon Laser katako na 1550nm.
Abubuwan zarra na Erbium suna aiki azaman matsakaicin Laser a cikin fiber doped, kuma hotunan da ake fitarwa suna kasancewa a cikin tushen fiber.Don ƙirƙirar rami wanda photons suka kasance a cikin tarko, ana ƙara wani abu da aka sani da Fiber Bragg Grating.
Bragg Grating wani yanki ne na gilashi kawai wanda ke da ratsi a cikinsa - wanda shine inda aka canza fihirisar refractive.Duk lokacin da hasken ya ketare iyaka tsakanin maƙasudin refractive ɗaya da na gaba, ƙaramin ɗan haske yakan koma baya.Ainihin, Bragg Grating yana sa fiber Laser yayi aiki kamar madubi.
The famfo Laser aka mayar da hankali a cikin cladding cewa zaune a kusa da fiber core, kamar yadda fiber core kanta ne ma kananan don samun low quality-diode Laser mayar da hankali a cikinta.Ta hanyar yin famfo Laser a cikin cladding a kusa da ainihin, Laser yana bounced a ciki, kuma duk lokacin da ya wuce ainihin, ƙarin hasken famfo yana ɗauka ta ainihin.
