Materials Research with Ultrashort Pulse Laser Source

The University of Bayreuth recently acquired an LPKF ProtoLaser R4 for processing a wide variety of materials. In the fields of gas sensor technology, high-frequency technology and microsystems technology, the device opens up new research opportunities for the university.

The LPKF ProtoLaser R4 laser system can generate ultra-short laser pulses of 1.5 picoseconds. Therefore, almost no heat transfer occurs during material processing with this laser: The material hit by the laser beam with pinpoint accuracy vaporizes immediately. As a result, surfaces in the micrometer range can be structured in a controlled manner without damaging the adjacent areas.

The Deutsche Forschungsgemeinschaft (DFG - German Research Foundation) provided 50 percent funding for the acquisition of the device at the Chair of Functional Materials.
