Laser World of Photonics and Congress in Munich
Munich, Germany — Laser World of Photonics, and the World of Photonics Congress will present the focus topics of "Lasers and laser systems for production engineering", "Green photonics" and "Biophotonics and life sciences" with a special emphasis on resource efficiency. One of the growth markets addressed in the context of the focus groups will be photovoltaics manufacturing.
Laser technology has proven superior in processes such as material removal, fusion, soldering, welding and drilling. In addition, lasers have become indispensable tools, especially in the manufacture of thin-film solar cells.
Production steps including solar module edge coating removal are already common. In addition, using ultra-fast pulsed lasers for solar module processes such as soldering and welding of edge insulation is becoming typical. Exhibitors offering solutions to these processes include 3D-Micromac AG, Chemnitz, InnoLas Systems GmbH, Krailing, LIMO Lissotschenko Mikrooptik GmbH, Dortmund, Newport Spectra-Physics GmbH, Darmstadt, Schott AG, Mainz, and Umicore Thin Film Products, Balzers, Liechtenstein.
Nanosecond laser pulses are frequently used in the production environment. Despite their very fast pulse, however, they are not suitable for some applications because the pulses are long enough to overheat the material. Future lasers for these processes will require picosecond and femtosecond pulses.
Exhibitors with picosecond and femtosecond lasers include Trumpf Laser GmbH + Co. KG, Schramberg, and Rofin Sinar Laser GmbH, Hamburg. Leading research institutes such as the Fraunhofer Institute for Laser Technology (ILT), Aachen, will complement the exhibitors by presenting the latest findings from applied research and will provide detailed information on production and machining methods from thin-layer structuring through to high-speed drilling of silicon wafers.
The practical talk entitled "Photovoltaics and Lasers" on May 24, will be primarily devoted to the topic of photovoltaics manufacturing. The speakers will be Dr. Ulrich Hefter from Rofin Sinar and Arnold Gillner from the Fraunhofer Institute for Laser Technology.
Another practical talk on this topic will be "Energy and Lightweight Construction: Laser Enables Productivity & Quality" on May 23. The speakers will be Dipl.-Ing. Rudiger Daub from the Institute for Machine Tools and Industrial Management (iwb) at Munich Technical University and Dipl.-Ing. Florian Albert from Bayerisches Laserzentrum GmbH, Erlangen.
