Abstract
A method for creating an iridescent effect on a surface through formation of wavelets on the source can include using a pulse of laser beams sent to the surface in juxtaposed optical fields of a focusing system. A scanner scans the surface using laser beams along a series of lines that follow each other in a relative direction of travel of the part and of the scanner and a series of lines that lie in continuation of each other in a direction perpendicular to the relative direction of travel. The optical fields overlap in an overlapping area having a width that is twice the diameter of the pulse laser beam up to 2 cm. Two lines lying in continuation of each other overlap at a junction and between the two series of lines follow each other in a relative direction of travel of the part and the scanner.
