Kuyini "Umthombo Okhanyayo Okhanyayo"

Kuyini "ukugqama okukhuluUmthombo Okhanyayo"? Wazi kangakanani ngakho? Ngiyethemba ukuthi ungabheka kahle ulwazi lwe-PhotoElectric Micro lwalethwa kuwe!

Umthombo okhanyayo we-Superradiant (owaziwa nangokuthiUmthombo wokukhanya we-ASE) ngumthombo wokukhanya okubanzi (umthombo wokukhanya omhlophe) osuselwa ku-superradiation. (Kuvame ukubizwa ngephutha ngomthombo omkhulu, okusekelwe kwinto ehlukile ebizwa ngokuthi i-superfluescence.) Ngokuvamile, umthombo wokukhanya omkhulu uqukethe i-laser ukuthola okuphakathi nendawo bese kukhulisa ukuze kukhanye.

Imithombo yama-Superradiant inokuhlangana okuphansi kakhulu kwesikhashana ngenxa ye-bandwidth yabo enkulu (ngokuqhathaniswa nama-lasers). Lokhu kunciphisa kakhulu amathuba okukhanya amabala akhanyayo, avame ukubonwa emishameni ye-laser. Kodwa-ke, ukuhlangana kwalo kwendawo kuphezulu kakhulu, futhi ukukhanya komphumela womthombo wokukhanya okhazimulayo kungagxila kakhulu (okufana nokhonkolo we-laser), ngakho-ke ukuqina kokukhanya kuphakeme kakhulu kunalokho kwesibani se-incandescent.

Kuyinto efanelekile ye-optics enamthole yomthombo opholile Bona ama-depemitting diodes ukuze uthole izinhlelo zokusebenza ezinemininingwane eminingi.

Omunye wemithombo engcono kakhulu yokukhanya yemisebe ye-Ultra Radiation Diode (Superluminescent DiadesI-SLD laser) ne-amplifier ye-fiber optical. Imithombo yokukhanya esekwe kwifafa inamandla aphezulu okukhipha, ngenkathi ama-SLD mancane futhi abizi kakhulu. Zombili zinemisebe ye-radiation ye-bandwidths okungenani enama-nanometers ambalwa namashumi ama-nanometers, futhi kwesinye isikhathi kube ngaphezu kwama-nanometers ayi-100.

Kuyo yonke imithombo ekhanyayo ephezulu ye-ASE, impendulo ye-Optical (isib Ingomaneamadivayisi we-fiber we-Optical fiber, URayleigh usakaza ngaphakathi kwefayibha ye-optical kuzothinta inkomba yokusebenza yokugcina.

Umdwebo 1: I-ASE Spectrum ekhiqizwe yi-fiber amplifier ibalwa njengejika emandleni entengo ahlukene. Njengoba amandla enyuka, i-spectrum iqhubekela phambili kwi-wavelength emfushane (inzuzo inyuka ngokushesha) kanye nomugqa wokubuka ongezansi. I-Waveveleth Shintshi ijwayelekile kwimidiya ye-quasi-ezintathu-inzuzo yokuthola izinsiza, ngenkathi umugqa we-line uvela cishe kuyo yonke imithombo ephakeme.
