Sublimation instead of melting
Advantages of the ultrashort pulse laser
HOW DOES ULTRASHORT PULSE LASER PROCESSING WORK?
In ultrashort pulse laser ablation, laser pulses hit a workpiece, whose electrons absorb the immense energy. The electrons transfer the energy to the atomic cores, resulting in highly precise heat localization. This causes the material to sublimate (evaporate) in a tiny zone before the surrounding material can heat up.
Classic laser
- damaged surface
- Heat transfer to surrounding material
- Formation of microcracks and fragments
Femtosecond laser
- no damaged surface
- no heat transfer 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 ÎŒm range and surface qualities down to Ra 0,1 ÎŒm. For industrial applications, this means fast and cost-effective 3D molding of the highest quality.
Variety of materials
With extremely short and powerful pulses, this laser gently processes almost any material, including:
- Carbide
- PCD, diamond
- Various steels
- Ceramics
- Sapphires, glass
- Semiconductor
- plastics
- Composites
design freedom
Ultrashort laser pulses open up new possibilities for designers. If, for example, wear, corrosion, heat resistance, or insulation are important for ceramics, the USP laser can process these just as well as other sensitive materials.

Frequently asked questions about ultrashort pulse laser application
How does ultrashort pulse processing work?
During laser ablation or cutting with an ultrashort pulse laser, laser pulses hit a component, whose electrons absorb the immense energy. The electrons transfer the energy to the cores of the atoms. This allows the heat to be localized with high precision. The material sublimates (evaporates) in this very small area before the surrounding material can heat up. This is why it is also referred to as "cold" laser processing.
How long does a femtosecond pulse last?
The blink of the human eye lasts between 300 and 400 milliseconds â a trillion times longer than the pulse length of the femto laser source used at HAILTEC.
What are the advantages of ultrashort pulsed lasers?
The main advantages of USP laser processing include material diversity, micro-machining and design freedom.
The ultrashort pulse laser offers several advantages over conventional lasers. First, it is capable of delivering very high energies in very short pulses. This allows it to work with great precision and create very complex structures. Second, the ultrashort pulse laser is much more robust and durable than conventional laser systems.
What is carbide?
Tungsten carbide is a composite material consisting 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 subject to high wear, such as when cutting hard materials. Tungsten carbide improves the quality of the tools and parts, extends their service life, and ensures safe and reliable processes. The downside: Tungsten carbide is difficult to machine.
Why is machining carbide so difficult?
Tungsten carbide is extremely wear-resistant and therefore difficult to machine. Precise adherence to quality specifications during the individual processing phases can significantly influence tool service life. Conventional processes include grinding and die-sinking. EDM is also very complex, as molds must first be produced. A further disadvantage is tool wear. However, punching technology demands maximum precision in tool components with repeatable accuracy â the ten thousandth part should be exactly the same as the first. Our laser system with the TRUMPF femto laser source excels in this regard, as laser processing enables significantly longer tool service life. In this regard, we work closely with Ceratizit, the market leader in supplying tungsten carbide to the punching technology industry.
