Awards presented every two years by AKL and ELI institute.
Aachen, Germany -- Outstanding innovations in laser technology were presented and honoured in the Coronation Hall of Aachen’s City Hall on May 4, 2022. The occasion was the presentation of the Innovation Award for Laser Technology in front of around 300 guests. This year's winners of the €10,000 award are Dr. Boris Regaard of TRUMPF Werkzeugmaschinen GmbH + Co. KG (2020) and Stefan Wolf of Primes GmbH. Both were able to impress the high-calibre jury with forward- looking projects.
In his laudation, Prof. John Powell from Lulea University of Technology, Sweden, praised the high quality of the projects and the innovative spirit of the award winners. The prizes for 2020 and 2022 were awarded together, as the 2020 award ceremony could not take place due to the pandemic.
The Innovation Award for Laser Technology is presented every two years to laser manufacturers and users as well as researchers and developers who have spearheaded a laser technology innovation from application-oriented research to successful industrial implementation. The organisers are the Arbeitskreis Lasertechnik AKL e.V., a network of around 180 laser experts, and the European Laser Institute ELI e.V., a platform that brings together expertise and knowledge of optical technologies.
Dr. Alexander Olowinsky, Chairman of the Board of the European Laser Institute ELI e.V., and Dipl.- Ing. Ulrich Berners, Chairman of the Board of AKL e.V., described the context of the award: “With the presentation of the Innovation Award for Laser Technology, we want to honour precisely those innovators who have spearheaded an invention in the field of production-oriented laser technology from research through development to market launch.”
The topic of the 2020 award-winning project was “Active Speed Control – Camera-Based Sensor System for Closed-Loop Feed Regulation in Laser Cutting”. At the heart of Active Speed Control, developed by Dr. Boris Regaard and his team at TRUMPF Werkzeugmaschinen GmbH + Co. KG, Ditzingen, is a camera-based sensor system in the cutting head, whereby real-time image processing analyses the camera data.
Based on the data analysis, the feed rate is constantly monitored for optimal results. This ensures maximum cutting speed and a more reliable process. The result is optimised productivity and less scrap and rework. The system has potential for controlling or monitoring other process parameters and is thus a milestone towards the development of a future, fully autonomous laser cutting machine.
The 2022 award-winning project was called "ScanFieldMonitor (SFM)". It was developed by Stefan Wolf, Head of Research and Development at PRIMES GmbH, Pfungstadt, and his team as a tool for laser scanner characterisation. The development was prompted by many new applications in the field of additive manufacturing and e-mobility.
The patented measurement principle enables the measurement of laser beam parameters by scanning vectors. The resulting laser scanner characterisation provides all geometric and laser-related parameters relevant for remote applications. In the same operation, beam position and movement of the laser scanner unit in the scan area are determined. The quality of the SFM's measurement principle becomes apparent whenever the behaviour of a dynamic laser plays a role.
The project which was awarded the second prize in 2020 is used in bomb disposal efforts. The innovation, entitled "New Laser Solution for Defusing Unexploded Ordnance (UXO) by the Use of a Disposable 3D Printed Tool Head," was developed by Dr. Oliver Meier, managing partner of LASER on demand GmbH, Burgdorf, together with the Laser Zentrum Hannover e.V. and the explosive ordnance disposal service of the Hamburg Fire Department.
The new approach involves creating a defined weakening in the cylindrical section of the bomb casing through a laser notching process, which then reduces pressure and thus the detonation force of the bomb. Subsequently, a controlled low energy input triggers a deflagration that is designed to rupture the shell at the notch and eject the detonator. An essential element of the project is the use of standard optical components at an affordable price. If damage occurs during bomb defusing, which is not unlikely, the components can be easily replaced.
The second prize in 2022 was awarded to the project "Innovative Surfaces using High-Speed Laser- Biomimetics" by Dr. Tim Kunze, Managing Director of Fusion Bionic GmbH, Dresden, and his team. Functional technical surfaces have so far been produced mainly by coatings and lithographic processes.
The potential of these techniques is currently limited, but Direct Laser Interference Patterning (DLIP) technology offers entirely new, limitless possibilities for surface enhancement. For example, surfaces can be created to which ice does not adhere (anti-icing, e.g., for aviation), or implants that are better accepted by the body thanks to their biocompatible and antibacterial surfaces.
Fusion Bionic has developed high-throughput manufacturing systems based on DLIP that are compact, robust, and up to 10 times faster than established processes. Without additional steps or chemicals, these DLIP modules create micro- and nanotextures on the surface at speeds of up to 1 m2/min.
“Unlimited Flexibility for Short Pulse Laser Applications” is what the neoMOS “SMART” laser system offers. The system, developed by Dr. Maik Frede of neoLASE GmbH in Hannover, Germany, implements the philosophy of developing new applications in laser micromachining through the flexible use of short pulse lasers.
The integrated ultrashort pulse laser for material processing enables pulse durations from nano to femtoseconds or a combination of different pulse durations in the same process. The basis for this is a novel amplifier technology. Combined with a modular MOPA platform, the "open source" philosophy makes it possible to exchange only a part of the laser (seeder) to set up completely new laser parameters. Different seed lasers allow pulse durations, repetition rates or pulse durations to be changed from the same laser system. It is an example of a new generation of machines that combines the functionality of several laser systems in just one machine.
The project by Thibault Bautze-Scherff, Head of Sales at Blackbird Robotersysteme GmbH, Garching b. Munich, is entitled "Finally United: OCT-Based Process Control and On-The-Fly Remote Laser Welding in One Tool". The joint development by Blackbird and SCANLAB GmbH, Puchheim, combines all classic monitoring tasks in laser welding in one tool. The combination of on- the-fly functionality, main scanner and OCT sensor is accessible via a common user interface. The system provides the flexibility that is increasingly in demand in production lines, for example to weld different parts in one station, each with its own process monitoring requirements.
