Laser Engraving Gold
Gold metal needs little introduction. Valued for its rarity and visual appeal, jewellery made of gold has been used since the olden times to convey affluence and elevated social status.
Nowadays, gold has become more accessible, with most consumers instead preferring their pieces to have a higher degree of personalisation and customisation. Pendants, rings, and charms are considered more valuable when etched with a person’s name, initials, or other personal inscriptions.
Laser engraving on gold has become a particularly effective and popular technology used toward this end.
Since the metal has a highly reflective surface, a pulsed fiber laser is a preferred technology to laser cut gold. By using a laser with a higher energy density, the heat is quickly absorbed by the material. Despite the use of a high energy laser, the parameters of a pulsed fiber laser can be adjusted to work with very delicate materials such as extremely thin or hollow gold items.
Pulsed fiber lasers have become the standard technology used specifically for gold items. A fiber laser concentrates high energy in an extremely fine laser beam, allowing gold etching of highly intricate and detailed designs. With a higher degree of control, a pulsed laser fiber does not damage the surrounding material, resulting in custom engraved jewellery with a clean finish.
