Laser gabaɗaya ya ƙunshi sassa uku
(1) Laser matsakaici aiki
Zamanin Laser dole ne ya zaɓi matsakaicin aiki mai dacewa, wanda zai iya zama gas, ruwa, m ko semiconductor.A cikin irin wannan matsakaici, ana iya gane jujjuyawar adadin ƙwayoyin cuta, wanda shine yanayin da ya dace don samun laser.Babu shakka, kasancewar matakin makamashi mai ƙarfi yana da fa'ida sosai ga fahimtar jujjuya lamba.A halin yanzu, akwai kusan nau'ikan kafofin watsa labaru masu aiki 1000, waɗanda za su iya samar da kewayon tsayin laser da yawa daga VUV zuwa infrared mai nisa.
(2) Tushen ƙarfafawa
Don yin jujjuyawar adadin barbashi ya bayyana a cikin matsakaicin aiki, dole ne a yi amfani da wasu hanyoyi don tada hankalin tsarin atomic don ƙara yawan adadin barbashi a matakin sama.Gabaɗaya, ana iya amfani da fitar da iskar gas don tada atom ɗin dielectric ta hanyar electrons tare da makamashin motsi, wanda ake kira kuzarin lantarki;Hakanan za'a iya amfani da tushen hasken bugun bugun jini don kunna matsakaicin aiki, wanda ake kira tashin hankali na gani;Ƙunƙarar zafi, haɓakar sinadarai, da dai sauransu. Hanyoyi daban-daban na tashin hankali ana ganin su azaman famfo ko famfo.Domin samun fitarwa na Laser ci gaba, wajibi ne a ci gaba da yin famfo don kiyaye adadin ƙwayoyin cuta a cikin babban matakin fiye da haka a cikin ƙananan matakin.
(3) Kogon rawa
Tare da kayan aiki masu dacewa da tushen haɓakawa, za'a iya gane juzu'i na lambar barbashi, amma ƙarfin tasirin radiation yana da rauni sosai, don haka ba za a iya amfani da shi a aikace ba.Don haka mutane suna tunanin yin amfani da resonator na gani don haɓakawa.Abin da ake kira na gani resonator shine ainihin madubai guda biyu tare da babban abin nunawa da aka sanya fuska da fuska a duka ƙarshen Laser.Ɗayan kusan dukkanin tunani ne, ɗayan kuma galibi yana nunawa kuma yana ɗan watsawa kaɗan, ta yadda za a iya fitar da Laser ta hanyar madubi.Hasken da aka nuna baya ga matsakaicin aiki yana ci gaba da haifar da sabon radiyo mai kuzari, kuma hasken yana ƙaruwa.Saboda haka, hasken yana oscillates baya da gaba a cikin resonator, yana haifar da amsawar sarkar, wanda aka haɓaka kamar avalanche, yana samar da ƙarfin laser mai ƙarfi daga ɗayan ƙarshen madubin tunani.
