The interaction of matter with light is one of the most fundamental processes occurring in nature with countless scientific and technological applications. In recent years, the continuing development of intense, ultrashort, coherent light sources from the mid-infrared (mid-IR) to the extreme ultraviolet (XUV) spectral range has opened new possibilities for the investigation of this interaction in new and complementary domains. In both the IR and XUV regimes, molecules and clusters of atoms interacting with light exhibit (correlated) multi-electron dynamics evolving on the few femtosecond (1 fs=10-15 s) to attosecond (1 as=10-18 s) timescale. Several experimental and theoretical investigations suggest that ultrafast multielectronic processes might be fundamental in determining the behaviour of molecules and clusters, and that understanding these phenomena might offer new perspectives on processes occurring on slower timescales, such as bond-breaking in complex molecules and Coulomb explosion in charged clusters. In this context, the main objectives of the MEDEA network are: 1) to advance attosecond and femtosecond XUV spectroscopy in molecules and clusters 2) to demonstrate the feasibility of nonlinear attosecond XUV spectroscopy, 3) to obtain benchmarks for the validation of attosecond tools and femtosecond XUV pulses for the time-resolved imaging of electron and nuclear dynamics in molecules, 4) to contribute to the development of new technological solutions that will increase the competiveness of the industrial partners 5) to train a group of early stage researchers (ESRs) and contribute to their career prospects, and 6) to increase the interest of young students in the networks core research field (Photonics) by introducing a dedicated experimental kit in several European secondary schools.

Worldwide there is great excitement about two new ultrafast XUV/x-ray sources that are presently coming available. Attosecond XUV pulses by high-harmonic generation (HHG) will now allow for the first time to make movies of ultrafast electron motion, and thereby to investigate photo-chemical processes beyond the Born-Oppenheimer limit. At the same time, XUV/x-ray Free Electron Lasers (FELs) based on self-amplification of spontaneous emission (SASE) of relativistic electrons moving through an undulator structure will allow for the first time to track structural changes in (bio-)molecules using femtosecond time-resolved x-ray diffraction. In this context, the objectives of ATTOFEL are six-fold: 1) by establishing a framework for collaborative research on attosecond science, the potential is created for major breakthroughs in our understanding of the role of ultrafast electron dynamics in atomic physics, molecular physics and materials science. 2) by bringing together groups who recently have combined research in attosecond science with research efforts at the FLASH-FEL in Hamburg, an effective channel is created for knowledge transfer between the HHG/attosecond laser community and the FEL-community, which have historically been separate. 3) a generation of young scientists is trained that can shape the future of attosecond and FEL science, or that can embark on successful careers in industry. 4) the competitive advantage that European attosecond science and European XUV/x-ray FEL facilities currently have is significantly aided. 5) the competitive position of European industrial partners in the very demanding high-end ultrafast lasers market is strengthened. 6) the structuring of the international research community in this field will be consolidated, strengthened and expanded.

The objective of this project is to set up an Initial Training Network on advanced techniques for ultrafast manipulation of atoms and molecules by strong femtosecond laser pulses. The project comprises a diverse range of applications of strong-field coherent control to ultrafast spectroscopy and microscopy; nuclear and electron wavepacket dynamics; alignment of molecules with applications to collisions, high harmonic generation and adsorption; characterization and control of dissipation; stabilization of cold atoms and molecules; quantum state and process tomography; and ultrafast information processing. The use of strong shaped femtosecond laser pulses opens a novel avenue to control of quantum dynamics via hitherto inaccessible physical mechanisms. The new control scenarios require the development of novel versatile femtosecond sources in the UV and VUV range of high shaping capabilities, to which a part of the research will be dedicated, with anticipated spin-offs of great multidisciplinary interest, e.g. in chemistry and biology. The combined expertise of the network - a joint effort of 10 universities and 3 industrial companies - represents the cutting edge of research and training in femtosecond light-matter interactions in Europe. The network will train 18 doctoral students and about 11 young postdoctoral researchers. The training activities will combine several dedicated instruments of network-wide training, capitalizing on their synergy with a backbone of specialized training inside the groups. The training program will be adapted to the ESRs, with elementary, advanced and expert phases initiated at the network schools and workshops. Prominent scientists from Europe and overseas, and industry leaders from the companies in the network and from outside, will contribute to the schools and workshops. Special attention will be focused on developing important complementary skills, such as communication, presentation, project planning and management.

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.

Carrier-envelope phase stabilization has opened an avenue towards achieving frequency metrology with unprecedented precision and optical pulse generation on the previously inaccessible attosecond timescale. Recently, sub-100-as pulse generation has been demonstrated, approaching the timescale of the fastest transients in atomic physics. However, further progress in attophysics appears to be limited by the performance of the traditional feedback approach used for carrier-envelope phase stabilization. Here, we demonstrate a conceptually different self-referenced feed-forward approach to phase stabilization. This approach requires no complicated locking electronics, does not compromise laser performance, and is demonstrated with 12-as residual timing jitter, which is below the atomic unit of time. This surpasses the precision of previous methods by more than a factor of five and has potential for resolving even the fastest transients in atomic or molecular physics. Such shot-noise-limited comb synthesis may also simplify progress in current research in frequency metrology. © 2010 Macmillan Publishers Limited. All rights reserved.

The aim of FUN OCT is to expand the non-invasive optical biopsy capability of optical coherence tomography (OCT) and combination of OCT with multiphoton tomography (MT) to develop novel functional capabilities hereby enabling morphofunctional performance, i.e., the fusion of anatomic and functional imaging at the cellular resolution level. These methodologies will enable unprecedented non-invasive detection of depth resolved physiological, metabolic as well as molecular specific tissue information, i.e., forming a novel, powerful medical imaging platform. This novel platform fills an important gap left by todays medical imaging technology. The hypothesis is that the combination of cellular resolution, real time imaging of morphology and depth resolved tissue function could enable a major step forward in early cancer diagnosis and in the early detection of retinal pathologies that are world wide leading causes of blindness. This is accomplished due to a synergistic effect from joining complementary international expertise in the fields of laser sources, OCT, MT and beam delivery system technology. The consortium comprises 6 research groups and 2 SMEs. The consortium will make use of its existing relations to clinical collaborators in order to achieve proof-of-principle validation of the imaging modalities. The outcome contributes directly to improving and to maintaining the quality of life and living conditions of the European aging population through early diagnosis of cancer and of retinal pathologies as well as more efficient therapy monitoring. Moreover, the envisaged imaging modality may in the long term act as a screening device to investigate the prevalence of cancer as a function of geographic (regional) or gender related parameters. Finally, the diagnosis of other age-related diseases in a variety of medical fields, such as cardiology, neurology, gynaecology, and gastroenterology, benefit from this novel diagnostic platform provided by FUN OCT.
