Research activities are related to the laser-based manufacturing process, in particular the use ultrashort laser pulses for laser nanotexturing for tribology, wettability, biomedical devices and OLED. The group is experienced in CAD/CAM programming to generate laser instructions for 5+3 axis laser manufacturing system.

Ultrashort laser cannot be delivered by optical fiber and the architecture of the current laser system are based on cartesian axis + galvo scanner with many constraints in treating big and hollow parts.

In ROBOMORE, aim is to use a robotic system to move a compact laser device with adaptive control of the relative position with respect to the workpiece.
