Laser surface texturing (LST) is a process in which a laser beam creates fine patterns or structures on the surface of a material.
Lasers are capable of creating microscopic patterns with a resolution of even nanometers. This enables the creation of complex, detailed structures that would be difficult or impossible to implement with mechanical means. With the right materials and settings, we can even achieve colors with laser technology. 
Since the laser beam works without contact, the chance of mechanical damage to the surface is minimal. This is important for materials that are prone to deformation or sensitive to physical influences. Laser surface patterning is extremely fast and can be automated, so patterning the surface of a large amount of products can be easily implemented.
Laser patterning can be used not only for aesthetic purposes, but also to improve functional properties, such as wear resistance, friction characteristics, wetting behavior or biocompatibility (for example, in the case of implants).
Areas of application
Automotive and machinery industry:
Laser texturing is used on friction surfaces to reduce the coefficient of friction and improve the distribution of lubricants. In the automotive industry, for example, it is used to form the surface structures of the internal parts of engines (pistons, cylinders).
Medical devices:
In the case of medical implants, laser-created patterns improve biocompatibility, helping tissues integrate more quickly with the implants. In addition, the surface treatment helps to reduce the adhesion of bacteria.
Electronics industry:
Laser patterning can be used to create very fine circuits on various materials, such as the surface of semiconductors. Laser technology is key to the miniaturization of electronic components.
Aesthetics and fashion industry:
With the help of lasers, unique patterns can be created on metal, leather, glass or textile surfaces, which enables the creation of unique design elements.
Aerospace industry:
Here, laser surface treatment is primarily used to improve the durability and frictional properties of aircraft components. The technology contributes to increasing the lifetime of components and reducing maintenance requirements.
Types of surface patterns that can be created
Microgrooves and microbumps:
These patterns are often used to provide better adhesion or lubrication to surfaces, such as bearings.
Precise holes and perforations:
Lasers are capable of making very fine holes and perforations, which are used for filters, sieves, or other systems that allow air or liquid to pass through.
Nanostructures:
Lasers allow the creation of nanoscale structures with special optical or biological functions.
