Workshop on beam shaping, analysing & monitoring at Laser World of Photonics 2019

Lasers are the tool of choice for many demanding tasks in material processing. But how to create the optimum beam profile? How can the quality of the laser beam and the processing result be analyzed or even continuously monitored during the process? What technologies are available on the market and are they suitable for my requirements? And what experiences have other users already had?

All these topics will be addressed at the workshop. On Tuesday, 25 June, seven technical experts will present all relevant facts and trends around the laser beam in material processing, as well as current technologies and share the experiences made with their application.

In his opening keynote, Alexander Denkl, Head of Application Engineering at Lessmueller Lasertechnik, will introduce Optical Coherence Tomography (OCT) as a tool for beam tracking, penetration depth measurement and seam monitoring from a user’s point of view. Dr. Malte Kumkar, TRUMPF Laser Application Center, will then demonstrate the potential of three-dimensional beam shaping for new and improved material processing. Artificial intelligence for real-time quality analysis of welding processes with a hybrid laser source in battery production is the subject of a joint presentation by Maurizio Gattiglio, Chairman Convergent Photonics and Giovanni di Stefano, Head of Materials and Process Technology, Comau.

Dr. Shogo Yagi, Senior Expert Engineer at NTT Advanced Technology, will introduce water-cooled, reflective Diffractive Optical Elements that can be used to change a laser beam’s intensity profile and focal depth. A system that allows the measurement and continuous control of size, position and power of a high-power laser beam directly at the workpiece will be presented by Oren Aharon, CTO of Duma Optronics. At the end of the workshop, Rodrigo Linares, Business Development Manager at NIT New Infrared Technologies, will show how an inline infrared camera can be used to measure the melt pool geometry at high speed and control it in a closed loop.
