Fiber lasers m'munda wa optical fiber communication

TheFiber Laseramatanthauza laser yomwe imagwiritsa ntchito ulusi wamagalasi osowa padziko lapansi ngati njira yopezera phindu. Ma lasers a CHIKWANGWANI amatha kupangidwa kutengera ma fiber amplifiers, ndipo mfundo yawo yogwirira ntchito ndi: tengerani chitsanzo cha laser chopopedwa motalika. Gawo la fiber doped ndi ayoni zitsulo zosawerengeka padziko lapansi limayikidwa pakati pa magalasi awiri omwe ali ndi mawonekedwe osankhidwa. Kuwala kwapampu kumalumikizana ndi ulusi kuchokera pagalasi lakumanzere. Galasi lakumanzere limatulutsa kuwala konse kwa mpope ndikuwonetsa laser kwathunthu, kuti agwiritse ntchito bwino nyali ya mpope ndikuletsa kuwala kwa mpope kuti zisamveke ndikupangitsa kuwala kosakhazikika. Endoscope yoyenera imalola gawo la laser kuti lidutse kuti lipange mayankho a mtengo wa laser ndikupeza kutulutsa kwa laser. Mafotoni pamlingo wapampu amatengedwa ndi sing'anga, kupanga ion number inversion, ndipo pamapeto pake amatulutsa mpweya wolimbikitsidwa mu doped fiber medium mpaka laser yotulutsa.

Makhalidwe a fiber lasers: Kulumikizana kwakukulu chifukwa laser sing'angayo ndiye sing'anga yamafunde. High kutembenuka dzuwa, otsika polowera ndi wabwino kutentha dissipation zotsatira; Ili ndi mayendedwe osiyanasiyana, kubalalitsidwa kwabwino komanso kukhazikika. Ma fiber lasers amathanso kumveka ngati otembenuza mafunde amphamvu, ndiye kuti, kutembenuza kutalika kwa mawonekedwe a pampu kukhala kutalika kwa ma ion padziko lapansi. Kutalikiraku uku ndiko kutulutsa kwakutali kwa kuwala kwa fiber laser. Sichiwongoleredwa ndi kutalika kwa pampu ndipo zimatsimikiziridwa ndi zinthu zomwe sizikusowa doping padziko lapansi. Chifukwa chake, ma semiconductor lasers amitundu yayitali yayitali komanso mphamvu yayikulu yofananira ndi mawonekedwe a ma ion osowa padziko lapansi atha kugwiritsidwa ntchito ngati magwero a pampu kuti apeze zotulutsa za laser zamafunde osiyanasiyana.

Gulu la CHIKWANGWANI laser: Pali mitundu yambiri ya fiber lasers. Malinga ndi sing'anga phindu, iwo akhoza m'gulu monga: osowa lapansi doped CHIKWANGWANI lasers, nonlinear zotsatira CHIKWANGWANI lasers, single crystal CHIKWANGWANI lasers, ndi pulasitiki CHIKWANGWANI lasers. Malinga ndi kapangidwe ka ulusi, amatha kugawidwa kukhala: ma laser ovala ovala limodzi ndi ma laser ovala awiri. Malinga ndi zinthu doped, iwo akhoza m'gulu la mitundu yoposa khumi monga erbium, neodymium, praseodymium, etc. Malinga ndi kupopera njira, akhoza m'gulu monga: kuwala CHIKWANGWANI mapeto nkhope kupopera, yaying'ono prism mbali kuwala lumikiza kupopera, kupopera mphete, etc. Malinga ndi kapangidwe ka pulasitiki CHIKWANGWANI patsekeke, iwo akhoza kukhala classified CHIKWANGWANI laser patsekeke; lasers, "8" zooneka patsekeke lasers, etc. Malinga akafuna ntchito, iwo akhoza m'gulu monga: pulsed kuwala CHIKWANGWANI ndi mosalekeza laser, etc. Kukula kwa CHIKWANGWANI lasers ikupita patsogolo.ma lasers apamwamba kwambiri, ultrashort pulse lasers,ndiyopapatiza-linewidth tunable laserszikutuluka wina ndi mzake. Kenako, ma fiber lasers apitiliza kukula motengera mphamvu zotulutsa, mtengo wabwinoko, komanso nsonga zapamwamba zamphamvu.
