Workshop of Photonics has a long-term experience in femtosecond laser surface micro-structuring.
Free from thermal effects pulses enable the creation of precise structures for desired applications.
A large variety of nano- and micro-scale structures can be controllably produced on diverse metallic and transparent materials using direct femtosecond laser processing techniques.
Functional surface modification

Laser surface structuring can be used to enhance various properties of surfaces or even induce new properties that material does not possess by itself, for example:
- Friction reduction/lubricant retention
- Diffractive structures for optical applications
- Micro molds for micro/nano feature replication
- Roughness modification
- Hydrophobicity/hydrophilicity
- Marking
By using a femtosecond laser, surface structuring can be performed on a variety of transparent materials.
The method is based on a very short pulse duration and large laser peak fluence. It allows structuring almost all classes of materials with ultra-high precision and without the occurrence of noticeable heat-affected zones.
Selective laser ablation

Selective laser ablation is one of the most common industrial lasers applications today.
It ensures high processing speed and high quality of a processed area.
Small portions of metal layers can be precisely removed without any damage to the substrate using femtosecond laser pulses. The depth and geometry of ablation may vary; therefore, it is suitable for a variety of applications.
Main features:
- High-speed laser processing
- No signs or burning
- No heat-affected zones
- High positioning accuracy
- High quality
- Micron resolution
