Yintoni "umthombo wokukhanya oqaqambileyo"

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 kunokwesibane 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 kwi-Fibre inamandla aphezulu emveliso, ngelixa i-SLD incinci kwaye inexabiso eliphantsi. Zombini zinemitha yee-nanometers ezimbalwa ubuncinci kunye namashumi eenanometers, kwaye ngamanye amaxesha zide zibe ngaphaya kwe-100 yeenanometers.

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, Ukusabalalisa kweRayleigh ngaphakathi kwefiber optical kuya kuchaphazela isalathisi sokusebenza sokugqibela.

umthombo wokukhanya oqaqambileyo

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.
