    Nd: YAG ul crystal waxaa loo isticmaalaa mashiinka calaamadeynta Laser iyo qalabka kale ee laser. 
    Waa walxaha kaliya ee adag ee sida joogtada ah ugu shaqeyn kara heerkulka qolka, waana kan ugu fiican uguna fiicnaanta waxqabadka laser.
    Sidoo kale, YAG (yttrium aluminium garnet) leysarka waxaa lagu muquunin karaa chromium iyo neodymium si kor loogu qaado astaamaha nuugista leysarka. Nd, Cr: YAG laser waa leysar adag oo dawladeed. Chromium ion (Cr3 +) waxay leedahay nuugis ballaaran band; waxay nuugtaa tamarta waxayna u wareejisaa ion neummium ions (Nd3 +) iyadoo loo marayo isdhexgalka dipole-dipole.
    Tallaabada leysarka ee Nd: YAG laser waxaa markii ugu horreysay lagu soo bandhigay Shaybaarada Bell sannadka markuu ahaa 1964. Nd, Cr: YAG laser waxaa lagu shubayaa shucaaca qoraxda. garaaca wadnaha oo gaaban ayaa la soo daayaa.
