Nd: ndodo ya kristalo ya YAG imagwiritsidwa ntchito mu makina ojambulira a Laser ndi zida zina za laser.
Ndizinthu zolimba zokha zomwe zimatha kugwira ntchito mosalekeza kutentha kwa chipinda, ndipo ndi laser crystal yochita bwino kwambiri.
Komanso, laser ya YAG (yttrium aluminium garnet) imatha kupangidwa ndi chromium ndi neodymium kuti ipititse patsogolo kuyamwa kwa laser. gulu;imatenga mphamvu ndikuitumiza ku ma ion a neodymium(Nd3+) pogwiritsa ntchito dipole-dipole interactions.Wavelength ya 1064nm imatulutsidwa ndi laser iyi.
Laser ya Nd:YAG laser idawonetsedwa koyamba ku Bell Laboratories mchaka cha 1964. The Nd, Cr:YAG laser imapopedwa ndi radiation ya solar. ultrashort pulses amatulutsidwa.
