    Nd: YAG kristalo ndodo imagwiritsidwa ntchito pamakina olemba laser ndi zida zina za laser. 
    Ndi zinthu zokha zolimba zomwe zingagwire ntchito mosalekeza kutentha, ndipo ndi kristalo wopambana kwambiri wa laser.
    Komanso, laser ya YAG (yttrium aluminium garnet) imatha kupangidwa ndi chromium ndi neodymium kuti ikuthandizire kuyamwa kwa laser. Nd, Kr: YAG laser ndi laser yolimba. gulu; imatenga mphamvu ndikuisamutsira ku neodymium ions (Nd3 +) kudzera munjira yolumikizirana ndi dipole-dipole. Kutalika kwa 1064nm kumatulutsidwa ndi laser iyi.
    Ntchito ya laser ya Nd: YAG laser idawonetsedwa koyamba ku Bell Laboratories mchaka cha 1964. Laser ya Nd, Cr: YAG imapopedwa ndi ma radiation a dzuwa. Mitengo yayifupi imatulutsidwa.
