At the LASER World of Photonics China, which will be held in Shanghai from March 15 to 17, 2016, the Fraunhofer Institute for Laser Technology ILT and Laserfact GmbH will be presenting laser tools and sample applications for joining, separating, deposition welding, and material ablation using ultrafast lasers. A presentation by Fraunhofer ILT scientist Christian Fornaroli will also explore the application possibilities of these extremely fast beam sources.
A trio of trade fairs all kicking off on the same date – March 15, 2016 – at the Shanghai New International Expo Centre (SNIEC) will also be a special event for China: electronica China, productronica China, and LASER World of PHOTONICS CHINA. At Asia’s leading trade fair for the full range of photonics products, Fraunhofer ILT is presenting four technical product highlights and a wealth of application know-how.

Multi-beam optics and combination head: speed and flexibility thanks to laser technology
“The four laser processing heads we’re exhibiting are a definite highlight,” explains Christian Hördemann, scientist at Fraunhofer ILT. Multi-beam optics are designed for use on ultrafast lasers. Thanks to the splitting of the beam into over 196 single beamlets, they permit processing speeds of several hundred structures a second. They are suitable for traditional surface structuring processes as well as for drilling, cutting, and other applications.
Another highlight is bringing previously unimagined productivity and quality advantages to the sheet metal industry while also offering maximum flexibility. Laserfact’s innovative combi-head unites cutting, component measurement, and welding in a single process chain, with one machine and one processing tool. Invented at Fraunhofer ILT, this technology is used for cutting strip ends to length and welding them in steel industry coating and inspection lines as well as in the manufacture of high-precision metal assemblies. Additional functionalities and fields of application of the latest combi-head generation will also be unveiled at the trade fair.
Between helical cutting and additive manufacturing
The third exhibit is guaranteed to make heads turn: the HelicalOptic v6 cutting head. Hördemann describes it thus: “A rotating laser beam moves in a circle like the Moon around the Earth. This rotation of the laser beam makes it possible to drill high-precision holes. When this drilling motion runs in a machine tool with a feed, helical drilling becomes helical cutting.”
In Shanghai, Fraunhofer ILT is also presenting a processing head for laser metal deposition. The process developed in Aachen has already proved its worth at well-known companies, where it has been used for near-net-shape repairing and for the manufacture of turbine components. It involves a laser beam melting a small part of the substrate and converting the powder into a fusion-bonded layer.
Ultrafast lasers on the rise
Ultrafast lasers are suitable in particular for precise applications that go easy on material – from drilling holes in printed circuit boards to processing diamonds. On March 16, 2016, Fraunhofer ILT scientist Christian Fornaroli will be discussing the possibilities for using ultrafast lasers in industrial manufacturing. In his presentation “Using ultrafast lasers for industrial applications: combining both excellent quality and high throughput” at the Shanghai New International Expo Centre (SNIEC), he will show how users can get the most out of the special characteristics of ultrafast lasers – excellent quality and high productivity.
Practical examples of ultrafast laser applications
The presentation is complemented by a variety of process examples drawn from industrial practice, which scientists will be explaining in detail at the Fraunhofer ILT stand. These range from laser-structuring tools and processing CFRP (carbon fiber reinforced plastic) components, to special solutions for the manufacture of batteries and solar cells. The latter case, for example, involves the industrial roll-to-roll production of solid-state lithium batteries or solar modules using thin-film technology.

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
Sizes and shapes of nuclei with more than 100 protons were so far experimentally inaccessible. Laser spectroscopy is an established technique in measuring fundamental properties of exotic atoms and their nuclei. For the first time, this technique was now extended to precisely measure the optical excitation of atomic levels in the atomic shell of three isotopes of the heavy element nobelium, which contain 102 protons in their nuclei and do not occur naturally. This was reported by an international team lead by scientists from GSI Helmholtzzentrum für Schwerionenforschung.
Nuclei of heavy elements can be produced at minute quantities of a few atoms per second in fusion reactions using powerful particle accelerators. The obtained...
