Laser cutting is applied for different kinds of materials where complex contours demand precise, fast and force-free processing. Lasers create narrow kerfs and thus achieve high-precision cuts. This method does not show any distortion and in many cases post-processing is not necessary as the component is subject to only little heat input and can mostly be cut dross-free.
Almost all kinds of metals can be laser cut: mild steel, stainless steel and aluminum are the most common applications. Other laser cut parts are made from wood, plastics, glass and ceramics. Compared to alternative techniques like die cutting, laser cutting is cost-efficient already for small-batch production. The big benefit of laser cutting is the localized laser energy input providing small focal diameters, small kerf widths, high feed rate and minimal heat input.

The laser beam welding is mainly used for joining components that need to be joined with high welding speeds, thin and small weld seams and low thermal distortion. The high welding speeds, an excellent automatic operation and the possibility to control the quality online during the process make the laser welding a common joining method in the modern industrial production.

The laser marks virtually all metals and plastics and various other materials with high contrast and without adding any undesirable substance. In most cases the typical physical effect of the laser induces a color change within the material so there is no surface modification by corrugations or burrs. Different marking methods and laser sources (solid state and CO2) are used, to achieve the best results on every type of material.

Lasers, especially high-frequency excited, fast modulating CO2 lasers with extraordinary power stability, are especially suited for perforating paper or plastic foils. Usually, web material is processed at winder systems at high speeds of up to 700 m/min. Hole diameters ranging from 50 - 400 microns can be achieved. Highly sophisticated systems like the ROFIN PerfoLas provide perforating speeds of up to 420,000 holes per second

Apart from the classical techniques of laser cutting and laser welding, lasers are used for surface treatment. Surface treatment is a collective term for applications where the laser radiation does not penetrate the material very deeply. This type of surface treatment is characterized by the fact that it changes the mechanical properties of an existing component.
