LASYS: LASERS IN ACTION Polygon scanner technology offers new
possibilities to exploit increasing laser performance. To improve throughput and reduce product processing costs without compromising accuracy, laser-scanner synchronisation becomes more necessary. In addition, a raster scan approach introduces an important design rule: required features need to correspond with a grid. Te presentation will show key system
considerations when designing a polygon scanner-based solution in order to achieve optimum results.

Direct laser interference patterning: fast, precise and cheap! Fabrication of micro and sub-micrometre structures in a one-step process
Professor Andrés Fabián Lasagni, Fraunhofer IWS Dresden
Smart surfaces are a source of innovation in the 21st century. Potential applications can be found in a wide range of fields where improved optical, mechanical and biological properties can benefit the functions of products. In this presentation, the fabrication of spatially ordered structures using direct laser interference patterning (DLIP) is demonstrated. Different application examples, including the processing of 2D and 3D surfaces are introduced and applied to improve the surface properties of polymers, metals and coatings. Initial investigations for large area structuring of stamps for 2D and roll-to-roll processing are also discussed.

Dynamic beam shaping for high power laser applications
Dr Andreas Wetzig, Fraunhofer IWS Dresden
Laser beam shaping is an established method to adapt the power distribution to the specific requirements of a particular laser application. Te first applications to use beam shaping are laser surface treatment applications, such as laser heat treatment. Dynamic beam shaping is more flexible compared to static beam shaping, so it allows a precise adjustment of laser power distribution, even during laser processing. Nowadays, dynamic beam shaping focuses more
12.30-13.30 Panel discussion: Future opportunities for laser technology
On Wednesday 1 June, from 12.30-13.30 on stand 4A51, a panel of experts will discuss future opportunities for laser technology. As well as hearing the panel’s thoughts on prospects for the laser market, visitors will be able to ask questions during the discussion.
The panel
Markus Rütering Sales manager Asia and Germany Laserline
Markus Rütering has more than 25 years’ experience in the laser industry, beginning with a job in R&D at Rofin-Sinar Laser, before moving into a variety of sales roles for the Rofin Group where, by 2008, he was executive product manager for all high power lasers. In 2011, Rütering moved to Laserline, where he was initially responsible for all sales in Asia, adding Germany to his territories in 2013.
applications. Coherent specialises in the development and production of lasers for industrial and scientific applications. Prior to his assignment with
Coherent, Kleine worked at Laserline as the general manager for US operations, Abbott Medical, DuPont and the Fraunhofer Institute for Laser Technology. Kleine holds a PhD from the University of Liverpool and MS (Dipl. Ing.) from Aachen University of Applied Science in Germany. Kleine holds 15 patents in the area of laser development, laser processing and medical device design. He is currently a member of the board of directors of the Laser Institute of America.
Dave MacLellan Executive director, Association of Industrial Laser Users (AILU)
Dave MacLellan has an engineering degree from Manchester University and 30 years of industrial experience in design, manufacturing, sales and marketing roles at companies such as JK Lasers and Rofin-Baasel. Using his extensive network of contacts and knowledge of the laser community, he established his own marketing company in 2014, and in 2015 he took over the day-to-day management of AILU and holds the role of executive director.
Lars Penning Managing director of Next Scan Technology (recently acquired by Scanlab)
A mechanical engineer by education, Lars Penning started out as an application engineer in factory automation. From 2002, he was head of business development and sales of engineering services in laser and vision-based systems. He co-founded Next Scan Technology in 2010 to transfer team knowhow on polygon scanner technology into laser material processing applications.
Moderator: Warren Clark Managing director, Europa Science, publishers of Laser Systems Europe
Warren Clark has worked in business-to-business publishing for more than 20 years, across a range of industries. Joining Europa Science at the outset in 2003, he was the launch editor for several of its titles, including Imaging and Machine Vision Europe and Laser Systems Europe. Clark joined the board of Europa Science in 2009 and, following a management buyout in 2016, is now the managing director and majority shareholder.
