“Khanya e phahameng haholo ke engmohloli o khanyang“?U tseba hakae ka eona?Ke tšepa hore u ka sheba hantle tsebo ea photoelectric micro e tlisoang ho uena!
Mohloli o khanyang oa superradiant (hape o tsejoa e leMohloli oa leseli oa ASE) ke mohloli oa khanya ea Broadband (mohloli o mosoeu oa leseli) o thehiloeng holim'a superradiation.(Hangata ka phoso e bitsoa mohloli oa superluminous, o theiloeng ketsahalong e fapaneng e bitsoang superfluorescence.) Ka kakaretso, mohloli o khanyang oa khanya o na le laser gain medium e ntšang khanya ka mor'a ho hlasimoloha ebe oa e holisa hore e hlahise khanya.
Mehloli e matla e na le momahano e tlase haholo ea nakoana ka lebaka la maqhubu a eona a maholo a mahlaseli (ho bapisoa le lasers).Sena se fokotsa haholo monyetla oa matheba a khanyang, a atisang ho bonoa mabaleng a laser.Leha ho le joalo, momahano oa eona oa sebaka o phahame haholo, 'me khanya e hlahisoang ke mohloli o khanyang oa mahlaseli a mahlaseli a kotsi a ka tsepamisoa hantle (e tšoanang le lebone la laser), kahoo matla a khanya a phahame haholo ho feta a lebone la incandescent.
Ke mokhoa o loketseng haholo oa optics coherent light source tomography (OpticalCoherenceTomography, OCT), tlhahlobo ea litšobotsi tsa lisebelisoa () ka puisano ea fiber ea optical, gyro le optical fiber sensor.Sheba li-diode tsa superemitting bakeng sa lits'ebetso tse felletseng.
E 'ngoe ea mehloli e meholo ea mahlaseli a kotsi bakeng sa diode ea mahlaseli a kotsi (Superluminescent DiodesSLD laser) le amplifier ea fiber ea optical.Mehloli ea leseli e thehiloeng ho fiber e na le matla a holimo, athe SLD eona e nyane ebile e theko e tlase.Ka bobeli li na le marang-rang a mahlaseli a bonyane li-nanometer tse seng kae le mashome a li-nanometer, 'me ka linako tse ling li feta li-nanometer tse 100.
Bakeng sa mehloli eohle ea mabone ea ASE e fumanang chelete e ngata, maikutlo a optical (mohlala, ho bonts'a ho tsoa ho li-fiber ports) a hloka ho hatelloa ka hloko, kahoo e baka phello ea laser ea parasitic.Bakeng salisebelisoa tsa optical fiber, Rayleigh ho hasana ka hare ho fiber optical e tla ama index ea ho qetela ea ts'ebetso.
Setšoantšo sa 1: ASE spectrum e hlahisoang ke fiber amplifier e baloa e le lekhalo ka matla a pompo a fapaneng.Ha matla a ntse a eketseha, mahlahahlaha a ea ho leqhubu le lekhutšoane (kalo e eketseha ka potlako) 'me mohala oa spectral o Narrows.Wavelength shifting ke ntho e tloaelehileng bakeng sa mecha ea phatlalatso ea quasi-tharo-level, ha ho fokotseha ha mela ho etsahala hoo e ka bang mehloling eohle ea superradiant.
