Ultra-short pulse laser
Your expert for ultrashort pulse laser application in contracting
Cutting-edge technology as a
contract service
With peak pulse powers of more than 300 MW, the ultrashort pulse laser processes even highly reflective surfaces. It works without heat-affected zones and without acting process force. For your components, this means no scratches, splashes, contamination or burrs. Reworking or cleaning of the surface is largely eliminated.

Advantages of the ultrashort pulse laser
HOW DOES ULTRASHORT PULSE LASER PROCESSING WORK?
In ultrashort pulse laser ablation, laser pulses strike a workpiece whose electrons absorb the immense energy. The electrons transfer the energy to the atomic trunks, which results in the heat being localised with high precision. Thus, the material sublimates (vaporises) in a minimally small zone even before the surrounding material can heat up.
Classic laser
- damaged surface
- Heat dissipation to surrounding material
- Formation of microcracks and fragments
Femtosecond laser
- No damaged surface
- No heat emission to surrounding material
- No formation of microcracks and fragments

Micromachining
Laser ablation, texturing or micro-laser cutting: The femtosecond laser does not heat the workpiece. This results in reproducible accuracies in the μm range and surface qualities down to Ra 0.1 μm. For industrial applications, this means fast and economical 3D molding in top quality.
Material diversity
With extremely short and powerful pulses, this laser gently processes virtually any material, including:
- Carbide
- PCD, diamond
- Various steels
- Ceramics
- Sapphire, glass
- Semiconductor
- Plastics
- Composites
Design freedom
Ultra-short laser pulses open up new possibilities for designers. For example, if wear, corrosion, heat resistance or insulation speak in favour of ceramics, the UKP laser can process them just as well as other sensitive materials.

Frequently asked questions about ultrashort pulse laser application
How does ultra-short pulse machining work?
During laser ablation or cutting with the ultrashort pulse laser, laser pulses hit a component whose electrons absorb the immense energy. The electrons transfer the energy to the hulls of the atoms. This localises the heat with high precision. The material sublimates (vaporises) in this very small area even before the surrounding material can heat up. This is why we also speak of "cold" laser processing.
How long does a femtosecond pulse last?
The blink of the human eye lasts between 300 and 400 milliseconds - a trillion times longer than a pulse length of the femto laser source used at HAILTEC.
What are the advantages of UKP lasers?
The main advantages of UKP laser processing include material diversity, micromachining and design freedom.
The ultrashort pulse laser offers a number of advantages over conventional lasers. For one thing, it is able to deliver very high energies in very short pulses. This enables it to work very precisely and create very complex structures. Secondly, the ultrashort pulse laser is much more robust and durable than conventional laser systems.
What is carbide?
Carbide is a composite material, it consists of a hard material and a very tough binder metal. The material is particularly hard, wear-resistant and has a high hot hardness. It is used wherever tools or components are exposed to high wear, for example when cutting hard materials. Carbide improves the quality of tools and parts, extends their service life and ensures safe and reliable processes. The downside: carbide is difficult to machine.
Why is it so difficult to machine carbide?
Carbide is extremely wear-resistant and therefore so difficult to machine. Precise adherence to quality characteristics in the individual machining phases can significantly influence the tool's service life. Conventional processes are grinding and die-sinking EDM. EDM is also very costly, as moulds have to be made first. Another disadvantage is tool wear. Punching technology, however, demands maximum precision in tool components - the ten-thousandth part should be exactly the same as the first. This is where our laser system with the TRUMPF Femto laser source scores points, as significantly longer tool service lives can be achieved through laser processing. Here we work closely with the Ceratizit company, which is the market leader in supplying the carbide for the punching technology industry.
