Nd:YAG Lasers Nd:YAG Lasers Nd:YAG is the acronym for yttrium aluminium garnet (YAG) and is a synthetic crystal material which became popular in the form of laser crystals in the 1960s. With a frequency of 1064nm, like the vanadate lasers, they produce high quality, high speed marking on a variety of substrates. The key features of the Nd:YAG laser include: Ÿ Marks metals, plastics, foils and ceramics Ÿ Easy to integrate into production lines Ÿ Highly flexible Ÿ Minimal maintenance required Ÿ Thermo electrical air cooling system comes standard with the machine The Nd:YAG laser is a good alternative to traditional marking systems because of its flexibility and minimal maintenance requirements.
