Abstract:

This project aims at the realization of a new technological platform for the development of a EUV – soft X-ray integrated photonics (X-PIC), a lab-on-chip instrument as coherent source for XUV and soft X-ray radiation. This platform X-PIC is based on high-order harmonic generation (HHG) of mid-infrared pulses in hollow-core waveguides. The miniaturized waveguides will be fabricated within the project consortium, these will be filled with noble gas which will serve as interaction medium for HHG of the laser pulses coupled in to the waveguide. In order to increase the the high-harmonic flux we will explore experimentally feasible quasi-phase-matching configurations through the controlled modulation of the waveguide's diameter and gas pressure.

Abstract:

The present project proposes to elaborate a detailed experimental and theoretical investigation in order to characterize in details the photochemical behavior of the polydopamine-based nanostructures. To achieve this goal, femtosecond time-resolved spectroscopy techniques (transient-absorption and time-resolved fluorescence) as experimental- and the density functional theory (DFT) and its linear response time-dependent (TDDFT) version will be considered as the theoretical framework to reveal the absorption efficiency of the electromagnetic field starting from the simpler dopamine to the more complex polydopamine (PDA) polymer structures, about the time scale of the excited state relaxation dynamics and the role of the graphene and TiO2 substrates on these photochemical processes of PDA. In the first period of the project implementation, the simple case of dopamine molecule will be analyzed. This investigation will be followed by a detailed description of the photochemical processes in PDA oligomers, oligomer aggregates and oligomer aggregates of PDA analogues. Finally, the more complex cases of PDA coated graphene and TiO2 nanostructure will be explored and the role of the substrates on the photochemical properties of the PDAs will be drawn up. Based on the system-level analyzes one can provide a comprehensive picture of photochemical properties of the PDA-based nanostructures that can be used to develop new materials with special properties.

Abstract:

During this project we intend to develop a numerical method for shaping femtosecond laser pulses to optimize the controlled generation of attosecond pulses which are used in time-resolved pump-probe experiments. We propose a fundamental type research, which contributes to a deeper understanding of the dynamics of electrons on the attosecond time scale. We will elaborate the pulse shaping method based on optimizing the electron trajectories in high-order harmonic generation (HHG) in two-color driving fields. The main goal of the project is to offer, as a final deliverable, a useful numerical tool for experimental groups in order to find the optimal configuration of their particular HHG setup and generate both intense and high-energy XUV (soft X-ray) attosecond pulses. The main goal of the project is to fill the gap between the results of theoretical calculations for the ideal waveform in HHG and the real experimental possibilities existing in laboratories.

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:

Generation of high-order harmonics (HH)is presently the main method to produce pulses of attosecond order duration. A monochromatic laser pulse induces this process every half optical cycle, thus, the harmonic emission is structured as a train of attosecond bursts which correspond to a comb of odd harmonics in the spectral domain. However spectroscopic and many other applications require single attosecond pulses (SAP) to be generated.

The project will explore SAP formation in macroscopic media in a novel configuration when three or more waveforms of incommensurate frequencies and femtosecond order duration are used as driving sources. A numerical model will be developed to (1) solve the wave equations for the simultaneous propagation of the waveforms in the ionizing gas (2) estimate the single dipole response of the atom to the combining fields and (3) solve the harmonic field propagation equations to calculate measurable quantities. The goals are (1) to model and explain SAP generation data which are obtained in collaborating laboratories (2) to find new field configurations able to achieve top characteristics (duration, intensity, broadband) of the attosecond bursts (3) to model and explain coherent beam combining experiments to be performed within romanian Extreme Light Infrastructure project.

Abstract:

The main objective of the project is to ensure the control of the ELI laser pulse temporally, spectrally and spatially, during its propagation, from generation to the target.
The specific objectives are in tight relation with the activities provided by the ongoing ELI project and are specified in the ELI Whitebook Sec B2:
O1. Establish a method for the complete characterization of laser pulses from a temporal, spatial and spectral point of view, in any given point of the beam path.
O2. Develop a numerical software as a component of the above method.
O3. Numerical modeling of the coherent combining of two laser beams (CBC).
The specific activities that we are proposing in this project follow from this methodology. They are in concordance with the objectives of the project and can be found in the achievement scheme.
O1.A1. Adapting the two methods for the propagation of a p-fs to the experimental characteristics existent in the ELI project: long propagation distances, low atmospheric pressure, high field intensities, specific focalization configuration, and so on.
O1.A2. Deciding together with the experimentalists the p-fs parameters which can be measured in the focal point, the location for measuring the pulse and the method for processing the experimental data.
O2.A1. Starting from the results of the O1.A2 activity: determine the temporal characteristics (pulse duration, chirp) from the spectral characteristics (spectrum and spectral phase), and the spatial characteristics (beam dimension at different locations, the radial profile of intensity) during the propagation from the generation point to the target.
O2.A2. Calculating the characteristics of the pulse during propagation and as a function of the residual pressure in the transport chamber. From these data, the admitted residual pressure values can be estimated as a function of the desired characteristics of the p-fs.
O2.A3. Optimization of the calculation method.
O2.A4. Performing several “virtual experiments” for the simulation of the propagation of the pulse in configurations specific to ELI-NP. Scanning the space for parameters in order to find the optimal configurations for the transport and manipulation of the pulse from the generation to the target.
O2.A5. Dissemination: publish an ISI paper and present the results at an international conference.
O3.A1. Implementing the coherent beam combining configuration in the complex model.
O3.A2. Evaluate the efficiency of the coherent beam combining of two laser pulses, knowing the two laser fields at the optical cycle level and at the wave front level.
O3.A3. Dissemination: publish an ISI paper and present the results at an international conference.

Abstract:

Producing ultrashort coherent XUV light pulses has become essential for real-time observation of electron dynamics in molecules and atoms. A well established method to obtain coherent XUV radiation is by the means of high-order harmonic generation (HHG) of ultrastrong few-cycle laser pulses in interaction with atomic/molecular systems in gas phase. There are two major concerns in this field of research: how to extend efficiently the HHG spectrum toward ever higher energies up to the keV regime, and how to isolate ever shorter XUV pulses down to tens of attoseconds (1asec=1e-18s). In this project we address both of these open problems and propose a new experimental scheme, namely HHG of ultrastrong few-cycle (near-)infrared (IR) pulses in the presence of a strong Terahertz (THz) pulse. In the first stage of the project an intensive modeling will be done. A complete 3D non-adiabatic numerical model will be extended and adopted for the treatment of HHG in the IR+THz case. Possible configurations of mutually perpendicular and parallel propagation directions for the two fields will be investigated. In both propagation schemes the two pulses can have mutually parallel or perpendicular linear polarization. Expected results are: prediction of cutoff extension; demonstrate experimentally the benefit of the THz assisting field; propose a feasible experimental scheme for THz assisted single attosecond pulse production.

Abstract:

Deciphering the complexity of chromatin-encoded information is the prerequisite for understanding the regulatory circuits governing development and (patho)physiology. Transcription factors and epigenetic modulators translate chromatin-embedded information in a dynamic and cell/gene context specific manner to orchestrate homeostasis, growth and differentiation. To date, the most powerful and commonly used approach is immunoprecipitation of chemically cross-linked chromatin (XChIP) coupled with single gene or global analysis using DNA tiling arrays (ChIP-chip) or parallel single molecule sequencing (ChIP-seq). At present, serious limitations of the XChIP technology preclude factor-DNA interaction studies at dynamic ranges below minutes. Moreover, conventional XChIP cannot be used to study samples of
