Dhammaan gaasku waxay u shaqeeyeen sidii shay leysarka ah oo loo yaqaan gaaska laysarka. Waa nooca adduunka ugu badan, horumarinta ugu dhaqsaha badan, adeegsiga laser-ka ugu ballaaran. Mid ka mid ah sifooyinka ugu muhiimsan ee gaaska laysarka waa qalabka shaqada laser waa gaas isku dhafan ama gaas saafi ah oo keliya.
Walaxda shaqaynaysa ee loo isticmaalo laser gaasi waxay noqon kartaa gaaska atomiga, gaaska molecular, gaaska ionized iyo uumiga birta, iwm. ). Laser), gaaska ion leysarka (sida argon laser), biraha uumiga laser (sida naxaasta uumiga uumiga). Guud ahaan, sababtoo ah sifooyinka dabiiciga ah ee gaaska laysarka, waxaa jira sifooyin qaar oo ka dhashay; Faa'iidooyinka ayaa ah: molecules gaaska ayaa si siman loo qaybiyaa, heerka tamartuna waa mid sahlan, markaa tayada iftiinka gaaska laysarka waa mid isku mid ah oo isku xiran. Ka wanaagsan; Intaa waxaa dheer, molecules gaasku way is rogaan oo si degdeg ah ayay u wareegaan, wayna fududahay in la qaboojiyo. Mid ka mid ah sifooyinka ugu muhiimsan ee gaaska laysarka ayaa ah in qalabka shaqada laser uu yahay gaas isku dhafan ama hal gaas saafi ah. Nadiifinta gaasta qaybta ee gaaska isku dhafan ee laysarka ayaa si toos ah u saameeya waxqabadka laser-ka. Gaar ahaan, joogitaanka wasakhda sida ogsijiinta, biyaha, iyo hydrocarbons ee gaaska waxay sababi doontaa luminta awoodda wax soo saarka laysarka ee muraayadda (dusha sare) iyo electrode-ka, sidoo kale waxay keenaysaa laydhka Unstable. Mid ka mid ah sifooyinka muhiimka ah ee gaaska laysarka gaaska, walaxda shaqada ee laysarka waa gaas isku dhafan ama hal gaas saafi ah. Sidaa darteed, waxaa jira shuruudo gaar ah oo loogu talagalay nadiifinta qaybaha gaaska isku dhafan ee laysarka. Dhululubada loogu talagalay baakadaha gaasta isku dhafan waa in sidoo kale la qalajiyo ka hor inta aan la buuxin si looga hortago wasakheynta gaaska isku dhafan. Haddii helium (He) neon (Ne) laser loo isticmaalo sidii jiilkii ugu horreeyay ee gaaska, iyo laser carbon dioxide waa laser gaaska jiilka labaad, laser krypton fluoride (KrF), kaas oo si weyn loogu isticmaali doono goobta wax soo saarka semiconductor. , waxaa lagu magacaabi karaa jiilka saddexaad ee laser. Isku darka gaasta laser waxaa loo isticmaalaa wax soo saarka warshadaha, cilmi baarista sayniska iyo dhismaha difaaca qaranka, qaliinka caafimaadka iyo qaybaha kale.
