Key halaye na Laser riba matsakaici

Menene mahimman halayen kafofin watsa labaru na samun laser?

Laser riba matsakaici, kuma aka sani da Laser aiki abu, yana nufin kayan tsarin da ake amfani da su cimma barbashi yawan inversion da kuma haifar da kara kuzari radiation don cimma haske ƙarawa. Shi ne core bangaren na Laser, dauke da babban adadin zarra ko kwayoyin, wadannan atoms ko kwayoyin a karkashin tashin hankali na waje makamashi, iya canzawa zuwa m jihar, da kuma ta m radiation fito da photons, ta haka forming ahasken laser. A Laser riba matsakaici na iya zama m, ruwa, gas ko semiconductor abu.
A cikin m-state Laser, da fiye amfani kafofin watsa labarai ne lu'ulu'u doped tare da rare duniya ions ko mika mulki karfe ions, kamar Nd:YAG lu'ulu'u, Nd:YVO4 lu'ulu'u, da dai sauransu A cikin ruwa Laser, Organic dyes ne sau da yawa amfani da matsayin riba kafofin watsa labarai. Laser gas na amfani da iskar gas a matsayin matsakaicin riba, kamar iskar carbon dioxide a cikin laser carbon dioxide, da helium da iskar neon a cikin laser helium-neon.Semiconductor Laseryi amfani da kayan semiconductor azaman matsakaicin riba, kamar gallium arsenide (GaAs).
Mahimman halaye na matsakaicin riba na Laser sun haɗa da:
Tsarin matakin makamashi: Atom ko kwayoyin da ke cikin matsakaicin riba suna buƙatar samun tsarin matakin makamashi mai dacewa don samun jujjuyawar yawan jama'a a ƙarƙashin kuzarin kuzarin waje. Wannan yawanci yana nufin cewa bambancin makamashi tsakanin mafi girma da ƙananan matakan makamashi yana buƙatar dacewa da makamashin photon na wani tsayin tsayi.

Kaddarorin canzawa: Atom ko kwayoyin halitta a cikin jahohi masu zumudi suna buƙatar samun tabbatattun kaddarorin mika mulki domin a saki hotuna masu daidaituwa yayin hasashe masu zumudi. Wannan yana buƙatar matsakaicin riba don samun ingantaccen ƙima da ƙarancin asara.
Thermal kwanciyar hankali da inji ƙarfi: A m aikace-aikace, da riba matsakaici bukatar yin tsayayya high ikon famfo haske da Laser fitarwa, don haka yana bukatar samun mai kyau thermal kwanciyar hankali da inji ƙarfi.
Ingancin gani: Ingancin gani na matsakaicin riba yana da mahimmanci ga aikin laser. Yana buƙatar samun haɓakar haske mai girma da ƙarancin watsawa don tabbatar da inganci da kwanciyar hankali na katako na Laser. Zaɓin matsakaicin riba na Laser ya dogara da buƙatun aikace-aikacenLaser, tsawon aiki, ƙarfin fitarwa da sauran dalilai. Ta hanyar inganta kayan aiki da tsari na matsakaicin riba, za a iya ƙara haɓaka aiki da ingancin laser.
