The LIFT project will establish international leadership for Europe in the science, application and production technologies for material processing by fibre lasers through the development of innovative laser sources. Major advances beyond the state of the art are planned: The cold-ablation fibre laser, based on ultra-short pulses, will open an entirely new market (100 mill. p.a.) for laser processing of ceramics. The extreme high-power fibre laser will enlarge the EUV lithography market (500 mill. p.a.) to include fibre lasers. The visible RGB fibre laser will produce the first high-brilliance source for laser projection displays (15 mill. p.a.). New future-oriented manufacturing tools based on higher-power pulsed fibre lasers (80 mill. p.a.). The high-reliability laser for large-scale manufacturing with High Speed Laser Remote Processing - means a new level of performance for 2kWatt materials-processing lasers with raised MTBF to 50.000 hours (accessible market 1 bill. p.a.). The Horizontal integration and networking in Europes high brilliance laser industry in this project will enable a greater market share for existing applications, create new areas of exploitation for manufacturing, and build a European network of component suppliers, laser manufacturers, universities and research institutes. As a result, LIFT will cause the following results to emerge: 1. Europe would take advantage of novel laser sources to be employed for various processing applications, many of which cannot even be treated by todays lasers. 2. European companies will benefit by the exploitation of the knowledge by the LIFT consortium in the field of fibre lasers, thus creating new markets and improving productivity in existing ones, thus building the competitiveness and the technological role of Europe; 3. The society as a whole would benefit from the results of LIFT, because in many sectors the further development of laser processing is crucial for the improvement of the quality

Over 400 attendees from 20 countries gathered from October 16-20, 2016 at the Sheraton® San Diego in San Diego, CA, for the 2016 Laser Institute of America’s International Congress on Applications of Lasers & Electro-Optics (ICALEO®). Gathering a highly engaged group of field veterans, new registrants and students, this year’s ICALEO featured more than 200 presentations, 59 peer-reviewed talks, comprehensive biophotonics coverage, and the introduction of the new ICALEO mobile app. Returning Congress General Chair Silke Pflueger was back at the helm helping compile the most highly-rated Opening Plenary presentations delivered at an ICALEO conference thus far. “We worked so hard this year to ensure, ICALEO 2016 once again exceeded all expectations,” said Pflueger. “Our opening plenary session is a great example. From visiting Mars, to self-driving cars and a LIGO revisit, we inspired new outlooks and forged new relationships, which is what ICALEO is all about.” Opening plenary speakers included Nina Lanza from Los Alamos National Laboratory, who linked humanity together in her discussion about the laser used aboard the Opportunity rover on Mars, and Jim McBride from Ford Motor Company, who talked about the challenges of sensing on fully autonomous vehicles. Albert Lazzarini, Deputy Director of LIGO Laboratory at California Institute of Technology, presented breaking results regarding black holes made from the first gravitational waves detected by LIGO. This year’s ICALEO also featured a variety of laser research and experimentation revelations, from the use of lasers in emerging areas, like paint stripping and dairy, to microprocessing and several new opportunities in wearables and medicine. Other highlights include LIA Executive Director Peter Baker’s honor as the first recipient of the new LIA Leadership Award. Retiring next April, Baker commented on his meaningful career: “At LIA we’re saving eyesight, preventing skin damage, and helping create laser technologies, products, and services that make the world a better place.” The 2016 Arthur L. Schawlow Award was awarded to Yongfeng Lu, the Lott Distinguished Professor of Engineering at the University of Nebraska-Lincoln, LIA Board Member, Past President, Treasurer and Fellow. LIA also honored Silke Pflueger and Neil Ball by elevating them to the highest level of membership as LIA Fellows. By unanimous decision, the first place ICALEO Poster Award went to Kohei Asano and his colleagues from Osaka University, the Industrial Research Institute of Ishikawa, and Yamazaki Mazak Corporation in Japan for their poster Copper Layer Formation Produced with 100W Blue Direct Diode Laser System, while the first place Student Paper Award winner was Christian Hagenlocher from IFSW in Stuttgart, Germany, for his paper Space and Time Resolved Determination of Thermomechanical Deformation Adjacent to the Solidification Zone during Hot Crack Formation in Laser Welding. As the 35th ICALEO ended, Neil Ball, newly-honored LIA Fellow, called the breakthrough laser event, “bar none, the best networking opportunity and the best opportunity to look forward and see what applications are on the horizon.” Ken Dzurko, General Manager of SPI Lasers said, “LIA does a great job creating a comfortable, relaxed mood right for exchanging ideas at this one-of-a-kind event that’s really the world’s premier gathering of scientists interested in laser applications.” ICALEO 2016 proceedings are available for sale at http://www.lia.org/store.

SPI Lasers and Electrox have teamed together to research and develop a new laser marking system based on a radically cost-reduced fibre laser. The fibre laser design is based on concepts demonstrated at SPI’s advanced laser laboratory in the Optoelectronics Research Centre at the University of Southampton. These will be further developed, and combined with SPI’s lean manufacturing technology to ensure a low cost product that has all the reliability and low cost of ownership advantages of fibre laser technology. Electrox will develop a highly configurable front end providing a new software user experience, greatly simplifying laser usage for both experienced and novice customers by including features for materials selection and parametric control. The result will be a radically cost-reduced product that will provide customers with maintenance-free operation at vastly improved efficiencies.
