The technique consists in focusing a laser beam. Each pulse then writes a very fine point up to a few microns. The laser beam is directed by an ultra-fast galvanometer scanner to draw the desired pattern (alphanumeric, matrix, or more complex shapes).
Laser marking is achieved by either ablation or modification of the surface condition of the material. It is precise, unalterable, without mechanical stress, fast, ecological and without contact.
Case of intra-volume marking
Femtosecond lasers can induce a local modification inside transparent materials such as glass, plastic or sapphire, without affecting the surface. This results in a marking technique that is particularly resistant to counterfeiting and is adapted to the pharmaceutical and the luxury industry.
