Yintoni "ekhazimlayo kakhulu"umthombo wokukhanya"? Unolwazi olungakanani ngayo? Ndiyathemba ukuba ungalubona kakuhle ulwazi oluvela kwi-photoelectric micro oluziswe kuwe!"
Umthombo wokukhanya oqaqambileyo kakhulu (okwaziwa ngokubaUmthombo wokukhanya we-ASE) ngumthombo wokukhanya we-broadband (umthombo wokukhanya omhlophe) osekelwe kwi-superradiation. (Idla ngokubizwa ngempazamo ngokuba ngumthombo okhanyayo kakhulu, osekelwe kwinto eyahlukileyo ebizwa ngokuba yi-superfluorescence.) Ngokubanzi, umthombo wokukhanya okhanyayo kakhulu uqulethe i-laser gain medium ekhupha ukukhanya emva kokuvuselela ize ikwandise ukuze kukhutshwe ukukhanya.
Imithombo ye-Superradiant ine-temporary coherence ephantsi kakhulu ngenxa ye-bandwidth yayo enkulu ye-radiation (xa ithelekiswa ne-laser). Oku kunciphisa kakhulu amathuba okuba kubekho amabala okukhanya, ahlala ebonakala kwi-laser beams. Nangona kunjalo, i-spatial coherence yayo iphezulu kakhulu, kwaye ukukhanya okuphumayo komthombo wokukhanya okhanyayo kakhulu kunokujoliswa kakuhle (ngokufana ne-laser beam), ngoko ke amandla okukhanya aphezulu kakhulu kunokukhanya kwesibane se-incandescent.
Yi-tomography efanelekileyo kakhulu ye-optics coherent light source tomography (OpticalCoherenceTomography, OCT), uhlalutyo lweempawu zesixhobo () kunxibelelwano lwe-optical fiber, i-gyro kunye ne-optical fiber sensor. Jonga ii-superemitting diodes ukuze ufumane iinkcukacha ezithe vetshe.
Enye yezona zibane ziphambili zemitha ye-ultra radiation diode (ii-Superluminescent Diodes)I-laser ye-SLD) kunye ne-optical fiber amplifier. Imithombo yokukhanya esekwe kwi-fiber inamandla aphezulu okukhupha, ngelixa i-SLD incinci kwaye ingabizi kakhulu. Zombini zine-radiation bandwidths ubuncinane yee-nanometers ezimbalwa kunye nee-nanometers ezilishumi, kwaye ngamanye amaxesha zingaphezulu kune-100 nanometers.
Kuzo zonke imithombo yokukhanya ye-ASE efumana i-high-gain, impendulo ye-optical (umz., ukubonakaliswa okuvela kwii-fiber ports) kufuneka kucinezelwe ngononophelo, ukuze kwenze i-parasitic laser effect.izixhobo zefayibha ye-optical, Ukusasazwa kweRayleigh ngaphakathi kwi-optical fiber kuya kuchaphazela isalathisi sokugqibela sokusebenza.
Umfanekiso 1: I-ASE spectrum eveliswa yi-fiber amplifier ibalwa njengegophe kumandla ahlukeneyo epompo. Njengoko amandla esanda, i-spectrum iya kwi-wavelength emfutshane (i-gain iyanda ngokukhawuleza) kwaye umgca we-spectral uyancipha. Ukutshintsha kwe-wavelength kuqhelekile kwi-quasi-three-level gain media, ngelixa ukuncitshiswa kwemigca kwenzeka phantse kuzo zonke imithombo ye-superradiant.
