Abstract:
The ARCOLAS project addresses an important topic fitted with specific thematic area of New Photonic Materials, namely design and testing as demonstrator of durable advanced antireflection (AR) coatings for plasma mirrors working in ultra-short TW/PW lasers systems.
It is intimate related to the existing high level technological ultra-short pulses lasers network facility in NILPRP (CO) and, with the aim and goal to upscale the obtained optical components for the unique ELI-NP facility to be built in the Magurele research area and where NILPRP is involved as partner.
The project answers to the demand for optical components used to ultra-short high power lasers systems because the number of these facilities is increasing and there are only two suppliers in the world.
The project will be developed in precise steps, following the concept in its theoretical and practical aspects.
First, the composition/combination of the dielectric materials with different refractive indices to be used as thin film(s) and/or heterostructures with antireflection properties will be studied.
The different layers will be obtained by pulsed laser deposition (PLD) and PLD assisted by a Radio-Frequency discharge (RF-PLD).
The experimental parameters for obtaining of each layer and of layers combination will be established after their careful characterization by specific techniques as AFM, XRD, spectroellipsometry, SIMS, SEM, HR-TEM, with high performance equipments belonging to the involved partners.
Then, optical components – demonstrators with controlled antireflection characteristics will be obtained based on dielectric layers with optimized properties and deposition architecture with the objective to be compatible with generation of plasma mirrors capable to withstand high energies ultra-short laser pulses.
Simultaneously, computer simulation studies regarding the phenomena that rise when a high energy ultra-short laser beam hits a material will be performed using Particle in Cell-Finite Difference Time Domain method.
Of a paramount importance in the project will be the components-demonstrator for plasma mirror testing in ultra-short high intensity laser field, in relativistic regime (intensities of 1018 W/cm2 - 1020 W/cm2). This will be made at INFLPR, where there is already established a complete and unique power-chain laser system: GIWALAS – GW, TEWALAS – TW and CETAL – 1 PW. The possibility of the direct access to these facilities will allow a rapid feedback regarding the AR coating behavior in the plasma mirror regime.
An important aspect is related to the prospective to use the demonstrator for the future 10 PW ELI-NP facility, where ultra-relativistic regime (1023 - 1024 W/cm2) are expected to be generated.
The industrial partner has the ability to design and produce the supports for optical components capable of withstanding high power ultra-short laser pulses.
The generated results will be the subject of patents first, as the topic is of vanguard, and of publications in high impact journal.

Abstract:
The ultrashort pulsed lasers are intensively used for fundamental research and technological developments in the field in material processing and characterization. In a "bottom-up" approach, under laser irradiation below the ablation threshold, periodical structures with sub-wavelength periodicity can be self-organized providing an efficient method for nano-texturing of large areas, for application such as fabrication of hydrophobic surfaces, bio-mimetic surfaces, surfaces with modified tribologic properties, colour marking of metals. However, some characteristics of the laser induced periodical surface structures (LIPSS), like poor contrast, bifurcations and truncations, can limit the functionality of the patterned surfaces. In order to find paths to control such patterns, more efforts have to be focused to the investigation of the mechanism formation of the nanostructures. The femtosecond lasers offer the unique possibility to simultaneously process and characterise the irradiated surfaces at time scale comparable with the dynamic of the nanostructures formations. The project proposes to develop time-resolved techniques for investigation of the mechanisms of the nanostructures formation, giving information about the build-up time of different types of nanostructures. An ultrafast holographic interferometry approach will be used for investigation of the time evolution of the irradiated surface at time scales of hundreds of picosecond with sub-picosecond time resolution.

Abstract:
This project addresses different aspects of science teaching at the pre-university level. The project “Inquiry-based education in science and technology: I-BEST” is focused on training school teachers and students to develop their own research projects, as a method to learn and a mean to serve the communities they belong to. By identifying the needs and expectations at European level as it concerns the development of a knowledge-based society which calls for the formation of an educated and responsible citizen, the project proposes the creation of a new model for science teaching in school. Using a student-centered approach, with training provided into a highly technical, cross-curriculum and collaborative environment, this project will assist schools teachers and students, to support science education in the frame of a national network. Courses and demo sessions about the educational training kits and materials developed in the frame of the project will be organized for school teachers. Some of them will benefit of the expertise of foreign teacher trainers. Two international conferences organized in the project frame will strength the links between the Romanian science teachers and experts from EU.

Abstract:
Nonlinear optics has revolutionized laser science by making it possible to efficiently convert laser light from one wavelength to another. Using the extreme nonlinear- optical process of high harmonic generation (HHG), light from an ultra-fast laser can be coherently up-shifted, resulting in a useful, tabletop, coherent and polarized short wavelength source. Such sources complement or replace expensive synchrotron facilities in specific applications.
The unique properties of UV HHG have already proven useful for studying ultra-fast molecular, plasma and materials dynamics, for characterizing nanoscale heat flow, for following element-specific dynamics in magnetic materials, and for high-resolution coherent imaging. HHG are ideal also for capturing the motion of electrons in atoms, molecules, and materials on their fundamental time (~fs) and length (~nm) scales.
Our project aims to develop at the TEWALAS laser system in INFLPR (15 TW, 10 Hz, 800 nm, 30 fs pulse duration), a HHG source technology as in [1] and also aims to build a facility to offer access to high flux radiation over the entire UV range. The major advantage is the ten fold increased UV production efficiency via quasi-phase matching control.
The expected impact of the development relates to a revolution in the efficiency of HHG sources, comparable with the one introduced by the periodically poled nonlinear crystals in laser physics. The optimized HHG sources will be patented and offered as high end products to the global ultra-fast laser market. The sources will also be the key elements at the core of a facility offering services related to the entire UV range, extending the capabilities of the TEWALAS laser facility. The commissioning of the UV user facility will be provided through a first experiment related to multi-coincidence photo-electron and photo-ion studies in diluted systems [2].

Abstract:
The project relies on an innovative, sound and unique combination of clean, environmental friendly and spatiotemporally accurate laser techniques for producing biofunctionalized conducting tridimensional scaffolds for tissue engineering. The project addresses the synergistic combination of major pillars of science and technology (Micro-Nano-Bio-Info), in the framework of Convergent Technologies for Improving Human Performance: (a) nano-micro science and technology-by using laser processing techniques for scaffolds fabrication; (b) biotechnology and biomedicine-by scaffolds biofunctionalization with biologically active agents and by analyzing the cells cultured within the scaffolds. (c) information technology-by developing advanced computing and application codes for tridimensional scaffolds fabrication and for monitoring the cells cultured within them. The laser techniques will be integrated in a three-step protocol, comprising scaffolds fabrication, biofunctionalization and testing. Rigid (titanium) and flexible organic-inorganic hybrid polymeric scaffolds will be obtained. Each of them will be biofunctionalized with polypyrrole-based conducting polymers combined with biologically active agents e.g. growth factors, drugs. Electrical stimulation of the scaffolds will trigger a spatiotemporally localized control of cell growth and the delivery of biologically active agents. The process occurs outside the body i.e. non invasive, ex vivo tissue engineering. This will lead to a new generation of biofunctionalized conducting tridimensional scaffolds with potential for bone/cartilage replacements, skin grafts and nerve regeneration. In all, the integrated platform proposed by the project will emerge as a new tissue engineering approach for modulating cell growth, proliferation and organization into functional tissues. The proposed methods based on clean, environmental friendly laser techniques will improve the therapeutic effects of tissue engineering technologies.

Abstract:
The ability of ultra-short laser pulses to induce permanent changes on the refractive index is nowadays attracting attention because of the unique possibility of three-dimensionally modifying at the micro and sub-micrometric scale the optical properties of the irradiated media. The main objectives of this project are: A) Realization of Nd-based waveguide lasers by direct writing with fs Ti:sapphire laser in single-crystal as well as all-poly-crystalline gain media; B) Laser emission in such waveguides at the fundamental wavelength of emission (0.9, 1.06 and 1.3 microns), as well as in visible spectrum employing multi-functional optical waveguides. Two hybrid waveguide lasers will be realized. The first one is a Nd laser passively Q-switched by Cr4+:YAG, with the gain media and the saturable absorber bonded optically together. The second one is a waveguide laser that incorporate the gain medium and a nonlinear crystal, and that generate laser radiation in visible range; C) Evaluation of some phenomena, such as spatial location, magnitude and nature of the micro-structural and refractive index changes, or modification of laser media spectroscopic properties during and after the process of waveguide writing, the investigations aim being theoretical modeling and explanation of the phenomenon. Applications of these waveguide laser devices include environmental monitoring, detection of noxes, optical systems for display technology, mobile telephones, or automobile industry.
