Ultrashort pulse lasers for large components

A paradigm shift is underway in manufacturing. A research team with staff from the Fraunhofer Institute for Laser Technology ILT in Aachen on its roster has broken new ground by using numerous laser beams as tools to structure surfaces. This accelerates the process and opens the door to new applications. The Stifterverband für Verbundforschung, a donors’ association for joint research, has seen fit to acknowledge the efforts of these researchers with its Science Prize.

Ultrashort pulse lasers can serve to apply functional microstructures and nanostructures to any surface. This type of laser machining is usually done by just one beam from a single source, a far too time-consuming and thus expensive approach to applying the micro- and nanostructures to the large embossing rollers that imprint textures and patterns on fabrics, leather and cardboard. This is why the practice of etching such structures into embossing rollers has prevailed. This is hardly ideal from the environmental perspective, but there was no economically viable alternative – until now, that is.

Anything but corrosive

A special sort of teamwork has turned laser structuring into a sound business proposition. Instead of a lone ultrashort-pulsed laser beam roaming the surface, the laser energy is split into many laser beams of equal power – specifically, into 200 partial beams. A special optical system serves to control these beams individually and modulate their power. This has created a new digitally-driven tool. With so many of these tools working the surface simultaneously, this process is manyfold faster than conventional laser machining. It is the first affordable option for machining large components. Developed in a joint project called MultiSurf, this technology owes its existence to Dr. Arnold Gillner, Martin Reininghaus and Dr. Johannes Finger from the Fraunhofer Institute for Laser Technology ILT, Dr. Stephan Brüning from Schepers GmbH & Co. KG, Dr. Gerald Jenke from Matthews International GmbH, Dr. Keming Du from EdgeWave GmbH Innovative Laser Solutions, and Dr. Manfred Jarczynski from LIMO GmbH. They have been singled out to receive the Science Prize from the Stifterverband für Verbundforschung for their efforts.

Stifterverband Science Prize

The Stifterverband is a consortium of approximately 3,000 companies, corporate associations, foundations and private individuals formed to jointly support progress in science and education. The Stifterverband uses subsidy programs, analyses and recommendations for action to ensure the proper infrastructure for innovation: high-performance universities, strong research institutes and productive exchange between business and science. The Stifterverband is a visionary body and an initiator of reforms - the model projects it supports drive changes in the system of innovation. The Stifterverband is a renowned voice in economics and in science and is an important partner to politics in matters concerning science and education.

For more than ten years, Stifterverband has supported the Fraunhofer-Gesellschaft through its Science Prize, endowed with prize money of 50,000 euros. This prize is awarded for scientific excellence in applied research projects conducted by Fraunhofer Institutes in collaboration with industry and/or other research organizations.
