The international jury composed by 10 members selected on the basis of merit and the published criteria 3 outstanding finalists among the 15 applications for the Innovation Award Laser Technology 2016 (see detailed descriptions of the three innovations including photos on www.innovation-award-laser.org).

The 3 finalists and their teams listed in final ranking:

1st Place

Team:
Dr. Ir. Armand Pruijmboom, Philips GmbH Photonics Aachen, Germany (Team Representative)
Dr. Günther Derra, Philips GmbH Photonics Aachen

Industrial manufacturing equipment for heating large areas with high throughput conventionally uses among others gas burners, hot air blowers and electrically or halogen lamp heated belt ovens. Due to their limited power density, high thermal inertia and low spatial selectivity, these heating methods can be switched on and off only slowly.

Furthermore, they are inaccurate and cannot easily deposit the heat only where it is needed or do not allow to impose sophisticated spatial thermal profiles on a work piece. On the other side conventional laser technology has disadvantages in this application mainly for cost reasons. Development of high power lasers has traditionally focused on brightness. Treating large surfaces with high brightness sources requires either complex optics or scanning systems. Each one comes along with technical limitations but more importantly with a severe cost impact. Vertical-cavity surface emitting laser-diodes (VCSEL´s) offer an innovative solution by heating only when and where it is needed in a short time with cost effective, compact and robust systems. Compared to conventional non-laser based heating technologies, VCSEL arrays offer flexibility, high efficiency and lifetime. As a solid state technology VCSEL´s fuel the trend to fully digitized manufacturing flows. The technology is bound to penetrate a large number of manufacturing processes and thereby adds a new and cost effective member to the family of high power lasers.


2nd Place
Laser Beam Remote Welding of Aluminium for Automotive Lightweight Design

The core of future automotive lightweight design is a flexible and at the same time stable joining technology of lightweight materials. A new approach in particular is laser beam remote welding of aluminium. The continuous challenge during this innovation was to combine the known options of laser beam remote welding of steel components with the material-specific properties of aluminium materials within a process. Up to now laser beam welding of monolithic aluminium joints, in particular using a fillet weld connection in a lap joint, has been realized only with tactile-guided processing optics. This results in an increase of process time. The laser beam remote welding demonstrates time savings of approximately 53% when compared to tactile laser welding. The method enables heat management control in the part. Exact positioning of the laser beam in relation to the edge reduces susceptibility to hot cracking because of precise weld penetration control. The gap dimension between the parts can also be determined during the joining process, and can be effectively closed by control strategies. Process efficiency is enhanced by eliminating the need for supplemental welding wire and protective gases. This reduces ongoing production costs. Moreover heat-related distortion is reduced. All of these advantages pay off, especially the ability to implement lightweight design with smaller flanges. The welds in the door frame of the Audi A8 illustrate this well. Audi is the first car manufacturer being able to use laser beam remote welding to join conventional aluminium alloys.

3rd Place
UVblade - Flexible Display Manufacturing by the Meter

Mobile devices with novel flexible displays have just started to enter the market. Smartwatches thin and light as a feather with round-shaped and high resolution
display as well as smartphones with individual display shapes and designs are found in everyday live and combine functionality with attractivity. The supply of curved TV- screens evolves continually. It is also conceivable to stow the complete hardware in a handle and pull the rolled up display out like an ancient papyrus scroll. As of today, the flexible display market is about to transform from a niche to a mass market.
The UVblade system provides a meter-long, thin blade of UV laser light which smoothly separates a flexible polymer layer from the rigid glass carrier in the so-called lift-off process. The separated display electronics layers reside thus on the lightweight and bendable polymer film resulting in a paper thin and flexible display. Via laser lift-off processing with the UVblade it is possible for the first time to transfer displays (LCDs, OLEDs, electrophoretic displays) to ten times thinner and more lightweight polymer
carriers. Alternative separation techniques are largely unsuitable for mass production.

Chemical etch processing for example is slow and unspecific while frequency- converted laser technologies provide only scarce output power in the UV. With the innovative development of the UVblade platform the Coherent team has brought an excimer laser system to the market which enables the cost-efficient volume production of the latest generation of flexible displays independent of the display diagonal.

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
