FEMTOPRINT is to develop a printer for microsystems with nano-scale features fabricated out of glass. Our ultimate goal is to provide a large pool of users from industry, research and universities with the capability of producing their own micro-systems, in a rapid-manner without the need for expensive infrastructures and specific expertise. Recent researches have shown that one can form three-dimensional patterns in glass material using low-power femtosecond laser beam. This simple process opens interesting new opportunities for a broad variety of microsystems with feature sizes down to the nano-scale. These patterns can be used to form integrated optics components or be developed by chemically etching to form three-dimensional structures like fluidic channels and micro-mechanical components. Worth noticing, sub-micron resolution can be achieved and sub-pattern smaller than the laser wavelength can be formed. Thanks to the low-energy required to pattern the glass, femtosecond laser consisting simply of an oscillator are sufficient to produce such micro- and nano- systems. These systems are nowadays table-top and cost a fraction of conventional clean-room equipments. It is highly foreseeable that within 3 to 5 years such laser systems will fit in a shoe-box. The proposal specific objectives are: 1/ Develop a femtosecond laser suitable for glass micro-/nano- manufacturing that fits in a shoe-box 2/ Integrate the laser in a machine similar to a printer that can position and manipulate glass sheets of various thicknesses 3/ Demonstrate the use of the printer to fabricate a variety of micro-/nano-systems with optical, mechanical and fluid-handling capabilities. A clear and measurable outcome of Femtoprint will be to be in a situation to commercialize the femtoprinter through the setting-up of a consortium spin-off. The potential economical impact is large and is expected in various industrial sectors.

Driven by the end-users requirements and needs, the main objective of the HIPERDIAS project is to demonstrate high throughput laser-based manufacturing using high-power, high-repetition rate sub-1ps laser. Although the laser system to be developed within HIPERDIAS can address other material processing applications, the focus here will be 3D structuring of silicon at high-speed, precision processing of diamond material and fine cutting of metal for the watch and the medical industry. Chirped Pulse Amplification (CPA) approach based on highly efficient compressors gratings will be implemented in order to minimize the overall losses of the laser system. The final targets of the project are to demonstrate:- a 10-times increase of ablation rate and productivity of large area 3D-structuring of silicon - a 10 times increase of speed in fine cutting metals - an increase of process speed (6-10 times) at a low processing tools cost of diamond machining Therefore, the laser parameters, as well as the beam shaping, beam guiding (based on Kagom fibers) and machine systems will be developed and optimized to fulfill the above manufacturing targets. The laser architecture will be based on fully passive amplifier stages combining hybrid (fiber-bulk) amplifier and thin-disk multipass amplifiers to achieve sub-500fs at an average output power of 500W and sub-1ps at an average output of 1kW, at a repetition rate of 1-2 MHz. Furthermore, second harmonic generation (SHG, 515 nm) and third harmonic generation (THG, 343 nm) will be implemented to allow processing investigation at these wavelengths. At 515 nm (respectively 343 nm) an average power of >=250W (respectively>=100W) shall be demonstrated.

More than 450.000 people are diagnosed with esophageal cancer (EC) each-year worldwide and approximately 400.000 die from the disease. Esophageal cancer is the eighth most commonly diagnosed cancer, but it is the sixth leading cause of cancer-related death, with incidence rates steeply rising. Risk factors, including gastroesophageal reflux disease and Barretts esophagus, may diagnostically implicate more than 300 million people worldwide. Nevertheless, the disease is detected late due to limitations in current diagnostic procedures leading to adverse prognosis and high treatment costs. ESOTRAC will change the landscape of esophageal diagnosis, over existing methods, based on cross-sectional optoacoustic and optical coherence endoscopy. The dual-modality system delivers a set of early-cancer imaging features necessary for improving early diagnosis, saving lives and leading to 3-5 Billion annual savings for the healthcare system. OCT provides micron scale subsurface morphological information based on photon scattering and optoacoustics provides deeper penetration and complementary pathophysiological features based on photon absorption. ESOTRAC develops novel photonic components (light sources, optical/optoacoustic scopes) and innovates novel medical system designs. Then, it performs pilot studies to investigate the functionality of the new endoscope and deliver a novel imaging-feature portfolio offering improved and earlier diagnosis. A central ESOTRAC ambition is that the new endoscope will become the new EC diagnostic standard by enabling quantitative and label-free three-dimensional endoscopy of early cancer with tremendous potential to impact esophageal care. ESOTRAC leverages European investment and know-how and strengthens the prospects of economic growth by leading the market position in endoscopic imaging.

Two-photon absorption is a photophysical process with diverse applications in medicine (photodynamic therapy), neurophysiology, cell biology (microscopy, photo-activated drugs) and biomedical engineering (fabrication of micro-needle arrays and tissue scaffolds). Many of these applications will only have a major impact when better dyes become available with stronger two-photon absorption, as well as improved secondary properties (photostability, biocompatibility, etc). Advances in optical engineering will also be critical. Two-photon absorption is an important newly emerging supra-discipline at the intersection of Biology, Chemistry, Physics and Engineering. This network will be the first initiative of its kind in this area. TOPBIO will train young researchers in many different aspects of the field, by coupling together research groups with internationally recognized expertise in synthesis, molecular design, theory, photophysics, photobiology, cell biology, engineering, nanotechnology, microscopy and laser physics. We aim not only to train ESR and ER in an interdisciplinary manner but also (by developing new generations of functional dyes and applying them in real biomedical applications) to improve the quality of life in Europe and to strengthen the EU economy. TOPBIO will provide an excellent mechanism for promoting interdisciplinary training, by exchanging PhD students on secondments between collaborating laboratories, through regular progress meetings, workshops and tutorial schools. TOPBIO brings together leading experts from universities and private sector organizations across Europe. It has an exceptional ratio of private to academic partners (1:2). The perfect match of complementary expertise, multidisciplinarity, high involvement of companies and focus on the real needs of society will enable us to deliver high quality training in skills which are perfectly matched to the needs of future employers, thus producing a workforce which will be in high demand.

Roll-to-roll manufacturing is well established in many segments like electronics, micro manufacturing or solar technology. Continuous roll-to-roll manufacturing processes can be integrated with various manufacturing steps within the production line. While many conventional and laser manufacturing techniques could already be embedded successfully into roll-to-roll machines, pulsed laser structuring could not be adapted sufficiently. The main obstacles are insufficient pulse repetition rate levels with required pulse energy and beam deflection speed and accuracy. The PoLaRoll project aim is to bring together current developments and fully integrate a high speed ultra-short pulse laser ablation process into a roll-to-roll machine fulfilling the requirements of individualised laser-based mass production. Various disciplines are in focus of the PoLaRoll project: A femtosecond laser will be developed with high pulse energy at extremely high pulse rates. Innovative polygon scanner technology for ultra-fast beam deflection is advanced in speed and accuracy and a dual polygon scanner will be developed enabling simultaneous laser structuring of top and bottom face of web material. An in-line metrology method will be developed enabling process monitoring and control. Highly sophisticated methods will be developed and applied enabling the synchronisation of the ground-breaking ultra-fast processing sub-systems. To prove the PoLaRoll process performance a target application has been selected, which is solar shading of glass facades. The laser formed micro structures geometry allows cutting the solar radiation and therefore reduces the energy used for cooling and ventilation. The PoLaRoll laser structuring module will be integrated into a prototypical modular designed roll-to-roll machine as well as in a conventional machine for mass production operated by the industrial end-user. Thus the PoLaRoll project will be able to revolutionise the current state of the art in digital roll-to-roll processing.
