    Nd: YAG crystal usheeda waxaa loo isticmaalaa in mashiinka calaamadaynta Laser iyo qalabka kale ee laser.
    Waa walxaha adag ee kaliya ee si joogto ah ugu shaqayn kara heerkulka qolka, waana wax qabadka ugu fiican ee laysarka.
    Sidoo kale, laser-ka YAG (yttrium aluminium garnet) waxaa lagu dhejin karaa chromium iyo neodymium si kor loogu qaado sifooyinka nuugista laser-ka Nd, Cr: YAG laser waa laser state adag. band;waxay nuugtaa tamarta waxayna u gudbisaa neodymium ions (Nd3+) iyada oo loo marayo isdhexgalka dipole-dipole.Wavelength of 1064nm waxaa sii daaya laserkan.
    Ficilka laser-ka ee Nd:YAG laser ayaa markii ugu horeysay lagu soo bandhigay Bell Laboratories sannadkii 1964. The Nd, Cr: YAG laser waxaa lagu shubaa shucaac cadceedda. By doping with chromium, awoodda nuugista tamarta laser waa la xoojiyey iyo garaaca garaaca gaagaaban ee ultra ayaa soo baxaya.
