Fiber Laser

Fiber lasers are widely used industrial laser sources for precise, fast and permanent marking and engraving. They are particularly suitable for metals and many engineering plastics and stand for high beam quality, dynamics and good integrability into systems and production lines. This makes them one of the key laser sources in industrial marking.

More about »Fiber Lasers«

Focus

The focus is the area of highest energy density of the laser beam on the workpiece. Its exact position directly influences contrast, line width, engraving depth and reproducibility. The focus is therefore a central parameter for the quality and stability of marking processes.

More about »Auto Focus – Automatic Focusing in Laser Marking«

Laser Engraving

Laser engraving is a material-removing process that creates a permanently recessed marking. Unlike purely color-based surface changes, material is deliberately removed. This makes laser engraving particularly suitable for robust markings, logos and functional structures.

More about »Laser Engraving«

Laser Marking

Laser marking is the umbrella term for processes in which a laser creates a permanent mark on a workpiece surface. Depending on the material and process objective, the effect is produced, for example, by annealing, ablation, foaming, color change or other material-dependent effects. The term therefore covers various marking principles used in industrial identification.

Laser Software

Laser software is used to create layouts, variable data, process parameters and workflows, as well as to connect peripheral devices and interfaces. It is essential for reproducible, safe and efficient marking processes. It therefore forms an important basis for controlling and standardizing industrial laser applications.

Pulse Duration

Pulse duration describes the temporal length of an individual laser pulse. It influences how energy is coupled into the material and whether the result is primarily ablation, discoloration, annealing or material-friendly precision processing. Pulse duration is therefore one of the key factors in selecting and fine-tuning laser processes.

More about »Marking Lasers«

Sample Marking

Sample marking is the practical preliminary test on original material or representative components. Marking process, contrast, heat impact, readability, engraving depth and the viable parameter window are evaluated under realistic conditions. It creates a reliable basis for selecting and assessing a solution.
