Laser gabaɗaya ya ƙunshi sassa uku
(1) Matsakaici mai aiki da laser
Samar da laser dole ne ya zaɓi hanyar aiki mai dacewa, wacce za ta iya zama iskar gas, ruwa, solid ko semiconductor. A cikin wannan nau'in matsakaici, ana iya gane juyewar adadin ƙwayoyin cuta, wanda shine yanayin da ake buƙata don samun laser. Babu shakka, wanzuwar matakin makamashi mai narkewa yana da matuƙar amfani ga cimma juyewar lamba. A halin yanzu, akwai kusan nau'ikan hanyoyin aiki 1000, waɗanda zasu iya samar da nau'ikan raƙuman laser iri-iri daga VUV zuwa infrared mai nisa.
(2) Tushen ƙarfafawa
Domin a sa juyewar adadin ƙwayoyin cuta ta bayyana a cikin hanyar aiki, ya zama dole a yi amfani da wasu hanyoyi don tayar da tsarin atom don ƙara yawan ƙwayoyin cuta a matakin sama. Gabaɗaya, ana iya amfani da fitar da iskar gas don tayar da ƙwayoyin halitta masu amfani da makamashin lantarki, wanda ake kira motsin lantarki; ana iya amfani da tushen hasken bugun jini don haskaka yanayin aiki, wanda ake kira motsin gani; motsin zafi, motsin sinadarai, da sauransu. Ana iya ganin hanyoyi daban-daban na motsawa a matsayin famfo ko famfo. Domin samun fitowar laser akai-akai, ya zama dole a ci gaba da yin famfo don kiyaye adadin ƙwayoyin cuta a matakin sama fiye da na ƙasa.
(3) Ramin amsawa
Da kayan aiki masu dacewa da tushen motsawa, ana iya gane juyewar adadin barbashi, amma ƙarfin hasken da aka ƙarfafa yana da rauni sosai, don haka ba za a iya amfani da shi a aikace ba. Don haka mutane suna tunanin amfani da resonator na gani don ƙara girma. Abin da ake kira resonator na gani a zahiri madubai biyu ne masu haske mai yawa da aka sanya fuska da fuska a ƙarshen laser ɗin biyu. Ɗaya kusan cikakken haske ne, ɗayan kuma galibi ana nuna shi kuma ɗan watsa shi, don haka ana iya fitar da laser ta madubi. Hasken da aka mayar zuwa ga hanyar aiki yana ci gaba da haifar da sabon hasken da aka ƙarfafa, kuma hasken yana ƙaruwa. Saboda haka, hasken yana juyawa baya da baya a cikin resonator, yana haifar da amsawar sarka, wanda aka ƙara girma kamar zaftarewar ƙasa, yana samar da fitowar laser mai ƙarfi daga ƙarshen madubin nuni na ɓangare.
