its harmonics (green, UV) should be selected for optimum processing. A laser which allows a variable adaption of its pulse parameters like energy, repetition rate and pulse duration can be of decisive advantage. Tis presentation features results of an application of Pharos laser for dicing, cutting, and nanostructuring of different transparent materials for which pulse energies of a few hundreds of microjoules is required. Employing the unprecedented flexibility and stability of the laser, it also demonstrates the results of material modification with submicrometer resolution allowing creation of sophisticated 3D structures inside the transparent media (transmission diffraction gratings, radial polarisation converters, etc.).

Femtosecond lasers for implantable medical device manufacturing
Dr Victor Matylitsky, Spectra-Physics/HighQ Laser
Femtosecond lasers have been around for several decades. Until more recently, though, they were complex, expensive, and required frequent tuning to sustain the demands of the production floor. Te Spectra-Physics’ Spirit industrial femtosecond laser is a proven, highly reliable and robust laser for micromachining and medical applications. Now, the Spirit laser is widely deployed in demanding applications around the world. In this paper, we will give an overview of actual applications for ultra-short pulse lasers for industrial micro-processing. In particular, the study on the impact of the processing conditions on the efficiency and quality of laser processing of poly-L-lactic acid (PLLA) polymer, which is commonly used for production of bio-degradable stents, will be presented.

CFRP cleaning with excimer lasers for optimised adhesive bonding
Dr Ralph Delmdahl, Coherent Laser-Systems
Carbon composite parts are formed to their final shape in a mold. Release of the form is simplified by using a release agent, which is based on oil. Tere are traditional methods for removing the agent such as manual grinding.

The lectures will be supplemented on 25 June by a panel discussion, titled: ‘Executive perspectives on the future of laser systems’. The panellists – Georg Hofner, CEO of Scanlab, Wolfgang Schulz at the Fraunhofer Institute of Laser Technology, Toni Koszykowski, CEO of the Laser SOS Group, and Mario Ledig, vice president of Jenoptik Laser – will deal with issues such as technology development and new applications, projects they are working on, and possible outlooks for the industry in ten years’ time. The discussion will be moderated by Warren Clark, publishing director of Laser Systems Europe.
Panellists
Georg Hofner CEO, Scanlab
Georg Hofner, born in 1963, studied physics at the University of Regensburg. After graduating, he worked for five years in the service and application department for a manufacturer of semiconductor production systems. In 1995 he started in technical sales at Scanlab, an independent OEM-manufacturer of scan solutions for the deflection and
positioning of laser beams, which is based in Puchheim near Munich. From 1996 to 2002 he was director of sales and marketing, and since 2002 has been CEO of the company.
Dr Mario Ledig Vice president, Jenoptik Laser
Since the beginning of 2014, Dr Mario Ledig has been the head of the Lasers Business Unit within Jenoptik’s Lasers & Material Processing division. He studied physics and earned his
doctorate in laser physics at the Friedrich Schiller University in Jena. Ledig has more than 20 years of professional experience in the fields of optics and photonics, and has held various executive positions at companies such as Qioptiq.
Wolfgang Schulz Head of department (Modelling and Simulation), Fraunhofer Institute of Laser Technology
As well as his role at the Fraunhofer Institute for Laser Technology, Dr Wolfgang Schulz is also professor of Non-Linear Dynamics, Laser
Obviously this process is very time consuming and not repeatable. Moreover, Trough manual grinding, fibres are regularly damaged. In turn, UV radiation selectively ablates the release agent and the resin surface, but not the carbon fibres. Excimer lasers at a wavelength of 308nm ensure material-friendly cleaning and can achieve cleaning rates of up to 50 m2
/hour.

Manufacturing Techniques, at the RWTH Aachen University. Since 2007, he has been Leader of the Excellence Cluster specialising in ‘Virtual Production Systems’ and a member of the steering committee for the Excellence Cluster ‘Integrative production for high-wage countries’ both at the RWTH Aachen University. In 2013, he was awarded the prize for excellence in teaching at the University’s Faculty of Mechanical Engineering.
Toni Koszykowski CEO, Laser SOS Group
Antoni Koszykowski studied at Cambridge Technical College and gained qualifications in physics, chemistry and business studies while working full-time. In 1987 he founded Laser SOS, a provider of direct retrofit laser parts for the most popular brands of industrial, scientific , medical and aesthetic laser systems. In 1997, he founded Laser SOS India which has become a world-leading producer of lamp- and diode-pumped systems for laser processing diamond gems. In 2002, Laser SOS-USA was founded, followed by the most recent addition to the group, Laser SOS Turkey, in 2008.
