Takulandilani ku Ruijie Laser

Kuwala CHIKWANGWANI CHIKWANGWANI laser kudula makina ndi mtundu wa sing'anga infuraredi gulu laser ndi CHIKWANGWANI laser monga zinthu ntchito (kupeza sing'anga).Zitha kugawidwa mu osowa lapansi doped CHIKWANGWANI laser, kuwala CHIKWANGWANI nonlinear zotsatira laser, single crystal CHIKWANGWANI lasers, CHIKWANGWANI arc lasers, etc..kutengera excitations kuyambitsa.Mwa iwo, ma lasers osowa padziko lapansi ndi okhwima kwambiri, monga doped erbium fiber amplifier (EDFA) amagwiritsidwa ntchito kwambiri pamakina olankhulirana opangidwa ndi fiber.Ma lasers apamwamba kwambiri amagwiritsidwa ntchito m'magulu ankhondo (kulimbana kwazithunzi, kuzindikira kwa laser, kulumikizana ndi laser, ndi zina), kukonza laser (kuyika chizindikiro cha laser, loboti ya laser, laser micromachining, etc.), zamankhwala ndi zina.

Fiber laser imapangidwa ndi SiO2 ngati matrix opangira magalasi olimba, omwe mfundo yake yowunikira ndikugwiritsa ntchito mfundo zonse zowunikira za chubu, ndiye kuti, kuwala kumatuluka kuchokera ku mawonekedwe owoneka bwino a refractive. cholozera ku chimodzi chazolozera zazing'ono za refractive zokhala ndi ngodya yayikulu kuposa yofunikira kwambiri, chiwonetsero chonse chidzawoneka ndipo kuwala kwa chochitikacho kudzawonetsedwanso ku mawonekedwe a optical density medium of high refractive index.Kuwala kumatuluka kuchokera ku optical kachulukidwe sing'anga (ndiko kuti, refractive index of the light in the medium is big) kupita ku mawonekedwe a optical sparse medium (ie, refractive index of the light ndi yaying'ono pakati), kuwala konseko kumawonekeranso mu sing'anga yoyambirira.Palibe kuwala kolowera mkati mwa mawonekedwe owoneka bwino omwe ali ndi index yaying'ono. 125μm) ndi zokutira zakunja zolimba za utomoni.Fiber optic propagation mode ikhoza kugawidwa mu single-mode (SM) fiber ndi multi-mode (MM) fiber.Single-mode fiber core diameter, yaing'ono m'mimba mwake (4 ~ 12μm) imatha kufalitsa mtundu umodzi wa kuwala ndipo mawonekedwe a kubalalitsidwa ndi ochepa.Multimode CHIKWANGWANI core diameter yomwe ndi yokhuthala (m'mimba mwake kuposa 50μm) imatha kufalitsa mitundu yosiyanasiyana ya kuwala pomwe kubalalitsidwa kwapakati kumakhala kokulirapo.Malinga ndi refractive kugawa mlingo, kuwala CHIKWANGWANI akhoza kugawidwa mu sitepe index (SI) CHIKWANGWANI ndi graded index (GI) CHIKWANGWANI.

Tengani ma lasers osowa padziko lapansi a doped fiber mwachitsanzo, okhala ndi tinthu tating'onoting'ono tapadziko lapansi ngati njira yopezera phindu, ulusi wa doped umakhazikika pakati pa magalasi awiri omwe amapanga phokoso lomveka.Kuwala kwapampu kumachitika kuchokera ku M1 kupita ku fiber kenako kumatulutsa laser kuchokera ku M2.Pamene kuwala kwa mpope kumadutsa mu ulusi, kumatengedwa ndi ayoni osowa padziko lapansi mu ulusi ndipo ma elekitironi amasangalala kwambiri kuti akwaniritse kusintha kwa chiwerengero cha particles.The inversed particles amasamutsidwa kuchokera ku mphamvu yapamwamba kupita kudziko lapansi ngati mawonekedwe a radiation kuti apange laser.
