Menene laser diode?

Laser ɗin Diode na'urar lantarki ce da ke amfani da mahaɗin PN tare da kayan semiconductor na binary ko ternary. Idan aka yi amfani da ƙarfin lantarki a waje, electrons suna canzawa daga mahaɗin conduction zuwa mahaɗin valence kuma suna fitar da makamashi, ta haka suna samar da photons. Lokacin da waɗannan photons suka yi ta nunawa akai-akai a mahaɗin PN, za su fashe wani ƙarfin laser. Lasers na Semiconductor suna da halaye na rage yawan aiki da aminci mai yawa, kuma ana iya daidaita mitar laser ɗinsu ta hanyar canza abun da ke ciki, girman mahaɗin PN, da ƙarfin sarrafawa.

Ana amfani da na'urorin laser na Diode sosai a fannoni kamar sadarwa ta fiber optic, faifan gani, firintocin laser, na'urorin daukar hoto na laser, alamun laser (alkalan laser), da sauransu. Su ne mafi girman na'urar laser dangane da yawan samarwa. Bugu da ƙari, na'urorin laser na semiconductor suna da amfani mai yawa a cikin jerin laser, LiDAR, sadarwa ta laser, makaman kwaikwayo na laser, gargaɗin laser, jagorar laser da bin diddigin laser, ƙonewa da fashewa, sarrafawa ta atomatik, kayan aikin ganowa, da sauransu, suna samar da kasuwa mai faɗi.
