Dab tsi yog "super radiant light source"

Dab tsi yog "super radiantqhov kaj"? Koj paub ntau npaum li cas? Kuv vam tias koj tuaj yeem pom qhov zoo ntawm photoelectric micro kev paub coj los rau koj!

Superradiant lub teeb ci (tseem hu uaASE light source) yog lub teeb pom kev dav dav (dawb lub teeb ci) raws li superradiation. (Nws yog feem ntau yuam kev hu ua lub superluminous qhov chaw, uas yog raws li ib tug txawv tshwm sim hu ua superfluorescence.) Feem ntau, ib tug superradiant lub teeb muaj ib tug laser nce nruab nrab uas radiates lub teeb tom qab excitation thiab amplifies nws emit lub teeb.

Superradiant qhov chaw muaj kev sib raug zoo ntawm lub cev tsis zoo vim lawv cov hluav taws xob loj loj (piv rau lasers). Qhov no zoo heev txo qhov muaj peev xwm ntawm lub teeb me ntsis, uas feem ntau pom hauv cov kab teeb laser. Txawm li cas los xij, nws txoj kev sib raug zoo yog qhov siab heev, thiab cov teeb pom kev zoo ntawm lub teeb ci ultra-radiant tuaj yeem tsom tau zoo (zoo ib yam li lub teeb laser), yog li lub teeb siv ntau dua li ntawm lub teeb incandescent.

Nws yog qhov tsim nyog heev optics coherent lub teeb ci tomography (OpticalCoherenceTomography, OCT), cov yam ntxwv ntawm cov cuab yeej tsom () hauv kev sib txuas lus fiber ntau, gyro thiab optical fiber ntau sensor. Saib superemitting diodes rau cov ntaub ntawv ntxaws ntxiv.

Ib qho ntawm cov hluav taws xob tseem ceeb tshaj plaws rau cov hluav taws xob hluav taws xob (Superluminescent DiodesSLD laser tshuab) thiab optical fiber amplifier. Fiber-raws li cov teeb pom kev zoo muaj lub zog tso zis ntau dua, thaum SLD me dua thiab raug nqi tsawg. Ob leeg muaj hluav taws xob bandwidths tsawg kawg yog ob peb nanometers thiab kaum nanometers, thiab qee zaum txawm ntau dua 100 nanometers.

Rau txhua qhov tau txais txiaj ntsig ntawm ASE lub teeb pom kev zoo, kev tawm tswv yim kho qhov muag (xws li, kev xav ntawm cov chaw nres nkoj fiber ntau) yuav tsum tau ua tib zoo tshem tawm, yog li nws tsim cov nyhuv parasitic laser. Rauoptical fiber ntau, Rayleigh tawg nyob rau hauv cov fiber ntau optical yuav cuam tshuam rau qhov kev ua tau zoo kawg.

Daim duab 1: ASE spectrum tsim los ntawm fiber ntau amplifier yog xam raws li ib tug nkhaus ntawm txawv twj powers. Raws li lub zog nce, lub spectrum txav mus rau qhov luv luv wavelength (qhov nce nce sai heev) thiab spectral kab Narrows. Kev hloov pauv wavelength yog ib txwm muaj rau quasi-peb-theem nce xov xwm, thaum txoj kab nqaim tshwm sim hauv yuav luag txhua qhov chaw superradiant.
