During more than 50 years of the laser existence, they have been proved as the unique tool for diverse material processing application. New application ideas, coming from universities and research institutions, are usually implemented by spin-off companies with limited resources for market penetration. Research laboratories are using universal laser tools, while effective and low-cost production requires adaptation of the processes and equipment during the technology assessment by the end-user.\nThe APPOLO project seeks to establish and coordinate connections between the end-users, which have demand on laser technologies for (micro)fabrication, knowledge accumulated in the application laboratories of the research institutes, as well as universities and the laser equipment manufacturers (preferable SMEs) of novel lasers, beam control and guiding, etc. The goal is to facilitate faster validation of the process feasibility and adaptation of the equipment for manufacturing, as well as assessment of the selected production processes. The core of the consortium comprises laser application laboratories around Europe which are connected into a virtual hub to accumulate knowledge and infrastructure and promote the easy-to-access environment for the development and validation of laser-based technologies. All the partners have chosen a few directions for the assessment of novel laser technologies: in ultra-short pulse laser scribing for monolithic interconnections in thin film CIGS solar cells - from lasers to pilot lines; use of the lasers and intelligent scanning in smart surface texturing for automotive and printing/decoration industries and for 3D flexible electronics.\nImplementation of the APPOLO project will help the partners from European photonics industry to preserve their competitiveness and penetrate new niches on the global market. The equipment builders for automotive, photovoltaics, electronics and printing industries will benefit from faster integration of innovative technologies which will provide the new-quality consumer products, including low-cost and high-efficiency solar cells, comfortable interior and functionality of cars, smart sensors for environmental monitoring and more.

X-ray mammography is the mainstay of breast cancer screening programs. It is estimated that between 20 - 50% of abnormal screening mammograms will prove to be negative. The paradigm in diagnosis is to establish whether a lesion is benign or malignant. All the imaging techniques conventionally used today diagnostic x-ray, ultrasonography and magnetic resonance imaging have many limitations, leading to multiple and/or repeat imaging and often unnecessary biopsy. This leads to physical, psychological and economic burdens felt at individual, familial and societal levels. With an aging population, high incidence of breast cancer and tightening health-care budgets, there is an urgent requirement for a non-invasive method for in-depth assessment of the screening-detected lesion. In PAMMOTH we will showcase such an imager, combining photoacoustic and ultrasound imaging. With the use of quantitative image reconstruction of multi-wavelength photoacoustic data, information is gained of the vascular and oxygen status of the lesion relating to tumor physiology and function. From the ultrasound part, we derive ultrasound reflection from the lesion in a manner superior to conventional breast ultrasonography, relating to anatomic features and extent of a tumor. This information will enable the radiologist to come to a diagnosis accurately and rapidly without the use of contrast agents, without pain and discomfort to the patient, while being cost-effective and not requiring complex infrastructure. Four excellent academic groups, three dynamic SMEs, and a hospital come together with support from key stakeholders in an Advisory group, to push beyond the state-of-the-art in science and technology to achieve the PAMMOTH imager. For the SMEs, in addition to tremendous improvements in individual product lines, the new integrated diagnostic imaging instrument opens up completely new market opportunities. We expect PAMMOTH to have a strong economic and clinical impact.

Terrorism is a real and growing threat to Europe and the world, and more than 60% of the terrorist attacks are carried out by the use of Improvised Explosive Devices. Security forces demand new tools to fight against this threat and the industry is making a big effort in the last few years to provide such tools. Every year a number of new products to detect and identify concealed explosives reach the market but up to the moment these new systems do not meet the full operational capabilities demanded by the end users. Probably the most demanded by the end users is the capability for standoff detection and identification of explosives, in order to be able to anticipate the threat from a safe distance and to avoid entering into the lethality area of an Improvised Explosive Device (IED). Such standoff detection capability is also very demanded for intelligence operations to identify materials, people or places involved in the preparation and transportation of explosives. In order to meet the end users needs, OPTIX will develop of a transportable system for the standoff detection and identification of explosives in real scenarios at distances of around 20 m (sensor to target), using alternative or simultaneous analysis of three different complementary optical technologies (LIBS, RAMAN, IR) and with the following characteristics: Standoff distance of at least 20 m. Detection of explosives in bulk, trace amounts and even liquids in certain conditions. Very fast detection and identification of explosives Very high specificity for the identification of explosives. Large operational availability of the system. Fully automated decision system (no operator dependence). In order to be successful, end users involvement in OPTIX is essential in the system specifications and validation, and in this sense the OPTIX consortium has put a special effort in including end users in those parts of the project where their contribution is relevant.

FBI fosters education of ESRs on an emerging, multimodal imaging platform and its translation into clinical and biological applications. In FBI, 15 ESRs are trained at world-leading European academic institutions and companies, thus forming strong interdisciplinary relations between industry, technical sciences and clinical end-users. Optical imaging has huge potential to address unmet clinical needs by combining non-invasive and real-time capture of biomedical information; thus enabling earlier onset of treatment, reduced therapy costs, reduced recurrence rates, and improved clinical outcomes. Up to now, optical modalities were applied as standalone techniques each targeting one biomarker. Recently it has been shown that diagnosis is significantly improved by combining different contrast mechanisms simultaneously in a multimodal approach, i.e., staging and grading of lesions is feasible. FBI proposes to combine a selection of modalities depending on the targeted disease. Suspicious lesions are analysed with optical coherence tomography, optoacoustic tomography, multi-photon tomography, and Raman spectroscopy to provide morphological, label-free microangiography, and intrinsic biochemical information, respectively. An important issue is the need for endoscopy: combining said modalities into endoscopes is challenging due to the integration of different imaging concepts, scanning and detection methods, and laser sources. Accordingly, there is a huge need for effectively translating these technical solutions to industry and clinics, which traditionally is restricted by lack of understanding of applications or limited knowledge of new technology. All these barriers are addressed by FBI through research and development of novel photonic components and systems, through educating ESRs in understanding clinical, biological and commercial challenges, and through developing tailored technical solutions and efficient translation of technology within a strong network.

Optical aberrations induced in thin-disk laser elements with an undoped layer, performing as an anti-ASE cap, are analyzed. A numerical model, used for calculations of the optical path difference (OPD) induced by temperature distribution inside the laser element and by deformation of surfaces, was confirmed experimentally. Results of numerical modeling manifest that adding an undoped layer on the thin-disk has detrimental effect on the reflected laser beam brightness and scaling. It is also shown that brightness of a thin-disk laser may be enhanced by the use of the Gaussian pump beam profile. © 2013 Optical Society of America.

The project described in this proposal aims at developing a new methodology to obtain semiconductor quantum dots (QDs) regioselectively in a polymeric matrix by means of a heating probe (laser). This new method is designed to produce light emitting devices (LED/T) based on semiconductor/polymer nanocomposite emission without using lithographic processes.This type of effect is possible because, after being heated, certain types of molecules produce metal or semiconductor QDs. If this process is carried out in polymeric foil, the resulting nanocomposite can be used for several purposes. It may be particularly appealing for industrial applications since it results in conducting/semiconducting micro/nano-regions in predetermined areas of the polymer without any patterning process. The potential applications of this technology can be utilized in many fields such as memory data storage, labelling of goods and, as proposed in this project, for the construction of displays.Producing a LED/T with this methodology requires selecting several types of polymers, metal-thiolate precursors (both metal and thiol group), lasers and LED/T architectures. To simplify the concept, the whole process sequence involves material synthesis as the first step, then the formation of the polymer/precursor foil, its laser irradiation in specific regions so that only the irradiated region will be enriched with QD, and, finally, testing the LED/T.Combining the electro-optical properties of QDs, the ease of processing of polymers and the use of laser will allow for the construction of a light-emitting device (LED/T) with increased life-time as well as obtaining matrices of LED/Ts (pixels) without any patterning or inkjet processing.The expected results of this project are: i) understanding the mechanism of the nanocomposites formation in situ and its optimization and ii) the formation of LED/T with enhanced electro-optical properties (QDs) without the use of any patterning process.

Rheumatoid arthritis (RA) and psoriasis arthritis (PSA) are destructive polyarthritic diseases having high incidence rates worldwide of about 1,5% and 0,5% respectively. Arthritis-related joint destruction leads to disabilities which result in a loss of patients quality of life, often include an inability to work and significant costs for healthcare systems. The functional outcome is strongly dependent on the time lag between the onset of the disease and the treatment beginning (ideally < 3-6 months). For early diagnosis allowing to improve the course of this devastating disease, sensitive and accurate diagnostic tools are required. Further, excellent image quality is needed for differentiated diagnosis (osteoarthritis vs RA or PSA) permitting the stratification of patient groups required for enabling a personalized therapeutical approach. Therefore, tools for early, precise and reliable diagnosis being affordable for screenings are of highest importance. Within IACOBUS, we suggest a new multimodal approach combining hyperspectral imaging with ultrasound (US) and optoacoustic (OA) techniques for diagnosis of arthritic diseases in finger joints. The proposed concept will allow the diagnosis and monitoring of arthritis based on imaging of early inflammation-induced hyperperfusion. Hyperspectral overview imaging for identification of suspicious joints will be combined with detailed high-resolution 3D imaging of affected joints (OA/US). Osteochondral information will be provided by high-frequency US while OA imaging will allow the high-sensitivity imaging of microvasculature in inflamed tissue. The consortium consisting of 4 SMEs and 3 academic partners will develop a novel non-invasive image-based diagnostic tool with significantly enhanced sensitivity for early arthritis symptoms and thereby allow to make use of the therapeutical window of opportunities. 50% of the overall project budget will go to SMEs which will ensure the exploitation of the developed platform.

A comparative theoretical analysis of continuously pumped actively Q-switched solid-state lasers differing in output coupling methods (cavity dumping versus a partially transmitting cavity mirror) is presented. Basic performance characteristics of the optimally coupled laser for periodic steady-state operation are expressed analytically. The instability effects are shown to fundamentally inhere in cavity dumping in contrast to ordinary Q-switching. The space of system parameters permitting stable operation and the maximum average power attainable as a train of regular energy pulses are determined numerically and verified experimentally. Cavity dumping is demonstrated to be the coupling method allowing Q-switched lasers to reach extremely high repetition rates. © 2011 Optical Society of America.
