From May 31st to June 02nd, 2016, international industry representatives will be coming to Stuttgart for an exchange about innovations, further developments and trends. The Laser Zentrum Hannover e.V. (LZH), too, together with the LZH Laser Akademie GmbH, will be presenting current research and development results, a broad services portfolio and further education programs for industrial laser users.
In hall 4 at stand E35, the research institute from Lower Saxony will be showing exhibits and services for laser micro processing with ultrashort pulse lasers, underwater laser cutting and additive manufacturing.
Highly precise and highly flexible: Manufacturing micro structures, sensors and functional surfaces with the laser
Laser micro processing enables manufacturing processes for components that are not possible with conventional manufacturing techniques. Here, ultrashort pulse lasers with pulse durations in the pico- and femtosecond range are used to generate highly precise and durable structures in almost all solid materials.
Another advantage of this process, besides the flexibly usable lasers, is that thermal and mechanical damages are negligible. Thus, for example thin-film strain sensors for measuring forces and momentums can be applied directly on the component. In this way, picosecond lasers generate functional surfaces with variable geometries by laser structuring. An application field for these surfaces is gravure printing in organic electronics.
Cutting metals faster and more cost-efficient underwater
Underwater works are often time-consuming and physically very demanding for the divers. The LZH develops an automated laser-based cutting process that increases the cutting speed significantly. Currently, the main application is cutting sheet pilings. But this laser-based process is also suited for repairing offshore-facilities and ships, as well as for dismantling nuclear power plants or for underwater mining.
Additive manufacturing using Selective Laser Melting and laser deposition welding
With Selective Laser Melting (SLM) it is possible to create smallest three-dimensional structures, complex parts or individual implants virtually “out of nothing”. The LZH develops processes for the additive manufacturing of load-adapted parts and for the processing of special materials, such as magnesium.
With Selective Laser Micro Melting (SLµM) it is thus also possible to manufacture parts with resolutions up to <30 µm. When high-quality machine parts are damaged, they can in many cases be repaired by Laser Metal Deposition welding (LMD). Moreover, adding layers by LMD can protect three-dimensional surfaces from wear and corrosion.
Further education seminar „Additive Manufacturing Specialist“
The LZH Laser Akademie GmbH, one of the leading further education centers in applied laser technology, together with the Schweißtechnische Lehr- und Versuchsanstalt (SLV) Hannover is nationwide the first to offer a new certified further education seminar “Additive Manufacturing Specialist”. In this five-day course, skilled workers, master craftsmen and technicians learn how to operate systems for Selective Laser Melting.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
