Yintoni “ebengezela kakhuluumthombo wokukhanya“?Wazi kangakanani ngayo?Ndiyathemba ukuba unokujonga kakuhle ulwazi oluncinci lwefotoelectric oluziswe kuwe!
Umthombo wokukhanya we-Superradiant (owaziwa nangokuthiUmthombo wokukhanya we-ASE) ngumthombo wokukhanya kwebroadband (umthombo wokukhanya okumhlophe) ngokusekelwe kwiradiation.(Kuhlala ngempazamo kubizwa ngokuba ngumthombo ogqithisileyo, osekelwe kwinto eyahlukileyo ebizwa ngokuba yi-superfluorescence.) Ngokubanzi, umthombo wokukhanya ogqithisileyo uqulethe i-laser gain medium ekhupha ukukhanya emva kochulumanco ize ikhulise ukukhupha ukukhanya.
Imithombo ye-Superradiant inokubambisana okwethutyana okuphantsi kakhulu ngenxa yobubanzi bayo obukhulu bemitha (xa kuthelekiswa ne-laser).Oku kunciphisa kakhulu amathuba okuba namabala okukhanya, ahlala ebonwa kwimiqadi ye-laser.Nangona kunjalo, ukuhambelana kwayo kwendawo kuphezulu kakhulu, kwaye ukukhanya okuphumayo komthombo wokukhanya kwe-ultra-radiant kunokugxilwa kakuhle (okufana ne-laser beam), ngoko ukukhanya kokukhanya kuphezulu kakhulu kunesibane se-incandescent.
Yinto efanelekileyo kakhulu ye-optical coherent light source tomography (OpticalCoherenceTomography, OCT), uhlalutyo lweempawu zesixhobo () kunxibelelwano lwefiber optical, i-gyro kunye ne-fiber optical sensor.Jonga ii-diodes eziphezulu malunga nosetyenziso oluneenkcukacha.
Omnye weyona mithombo yokukhanya yemitha ye-ultra radiation diode (i-Superluminescent DiodesI-laser ye-SLD) kunye neamplifier yefiber optical.Imithombo yokukhanya esekwe kwiFibre inamandla aphumayo aphezulu, ngelixa i-SLD incinci kwaye inexabiso eliphantsi.Zombini zinemitha yokusasazeka kwemitha ubuncinane yeenanometers ezimbalwa kunye namashumi eenanometers, kwaye ngamanye amaxesha zide zibe ngaphezulu kwe-nanometers ezili-100.
Kuyo yonke imithombo yokukhanya ye-ASE ephezulu, impendulo ye-optical (umzekelo, imbonakalo evela kumazibuko efiber) kufuneka icinezelwe ngononophelo, ngoko ke yenza i-parasitic laser effect.Kubaizixhobo zefiber optical, Ukusasazwa kweRayleigh ngaphakathi kwefiber optical kuya kuchaphazela isalathisi sokusebenza sokugqibela.
Umzobo 1: I-ASE spectrum eveliswa yi-fiber amplifier ibalwa njengegophe kumandla ompompo ahlukeneyo.Njengoko amandla esanda, i-spectrum ihambela kwi-wavelength emfutshane (inzuzo iyanda ngokukhawuleza) kwaye umgca we-spectral uyancipha.Ukutshintsha kweWavelength kuqhelekile kwi-quasi-three-level gain media, ngelixa ukucutha komgca kwenzeka phantse kuyo yonke imithombo yokukhanya.
