The laser-based marking and labeling of workpieces is amongst the more established
laser applications.
A desired surface inscription or mark can be obtained in different ways.
In the case of surface engravings, short high-energy laser pulses are applied to a
workpiece, in order to evaporate material at its surface.
Typically, this creates an indentation mark with a certain pile-up around its outline and
related discoloration effects.
A discoloration of the workpiece's laser inscription area without any damage to the
actual surface is successfully achieved by steel temper marking techniques.
To function properly, this type of laser inscription technique requires steel with a
carbon content. Color changes by laser marking can also be achieved on hard
metals.
Another marking application is the partial removal of previously applied paint,
coating or finish layers.
JENOPTIK Laser, Optik, Systeme GmbH provides highly compact diode-pumped
solid-state lasers for marking of different materials.
