Menene "mai haske sosai"tushen haske"? Nawa ka sani game da shi? Ina fatan za ka iya kallon ilimin da aka kawo maka ta hanyar amfani da na'urar daukar hoto mai amfani da hasken rana (photoelectric micro knowledge) sosai!
Tushen haske mai haske (wanda aka sani da Superradiant)Tushen hasken ASE) tushen haske ne mai sauri (farin haske) wanda aka gina shi akan hasken superradiation. (Sau da yawa ana kiransa da kuskure tushen superluminous, wanda ya dogara ne akan wani abu daban da ake kira superfluorescence.) Gabaɗaya, tushen haske superradiant yana ɗauke da hanyar samun laser wanda ke haskaka haske bayan motsawa sannan ya ƙara shi don fitar da haske.
Tushen hasken superradiant suna da ƙarancin haɗin kai na ɗan lokaci saboda girman girman haskensu (idan aka kwatanta da lasers). Wannan yana rage yiwuwar samun tabo na haske sosai, waɗanda galibi ake gani a cikin hasken laser. Duk da haka, haɗin kai na sararin samaniya yana da yawa, kuma hasken fitarwa na tushen hasken ultraviolet mai haske zai iya zama mai da hankali sosai (kamar hasken laser), don haka ƙarfin hasken ya fi na fitilar incandescent girma.
Tsarin daukar hoto ne mai dacewa sosai ta hanyar amfani da hasken haske (OpticalCoherenceTomography, OCT), nazarin halayen na'ura () a cikin sadarwa ta fiber optic, firikwensin gyro da fiber optic. Duba diodes masu ƙarfi don ƙarin cikakkun bayanai.
Ɗaya daga cikin manyan hanyoyin samar da hasken rana (Superluminescent Diodes) shine don samar da hasken ultraviolet.Laser na SLD) da kuma amplifier na fiber optical. Tushen haske na fiber suna da ƙarfin fitarwa mafi girma, yayin da SLD ƙanana ne kuma ba su da tsada. Dukansu suna da bandwidth na radiation na akalla 'yan nanometers da goma na nanometers, kuma wani lokacin ma sun fi nanometers 100.
Ga duk hanyoyin hasken ASE masu yawan riba, ana buƙatar a danne martanin gani (misali, haske daga tashoshin zare) a hankali, don haka yana haifar da tasirin laser mai kama da na'urar.na'urorin fiber na gani, Rarraba Rayleigh a cikin zare na gani zai shafi ma'aunin aiki na ƙarshe.
Hoto na 1: An ƙididdige bakan ASE da aka samar ta hanyar amfani da amplifier na fiber a matsayin lanƙwasa a ƙarfin famfo daban-daban. Yayin da ƙarfin ke ƙaruwa, bakan yana motsawa zuwa ga gajeren tsawon rai (ribar tana ƙaruwa da sauri) kuma layin bakan yana raguwa. Canjin tsawon rai al'ada ce ga kafofin samun maki uku, yayin da takaita layuka ke faruwa a kusan dukkan hanyoyin superradiant.
