Streszczenie:
We investigated tip-enhanced Raman spectra excited by high-order fiber vector beams. Theoretical analysis shows that the high-order fiber vector beams have stronger longitudinal electric field components than linearly polarized light under tight focusing conditions. By introducing the high-order fiber vector beams and the linearly polarized beam from a fiber vector beam generator based on an electrically-controlled acoustically-induced fiber grating into a top-illumination tip-enhanced Raman spectroscopy (TERS) setup, the tip-enhanced Raman signal produced by the high-order fiber vector beams was 1.6 times as strong as that produced by the linearly polarized light. This result suggests a new type of efficient excitation light beams for TERS.

Streszczenie:
GlueX at Jefferson Lab aims to study the light meson spectrum with an emphasis on the search for light hybrid mesons. To this end, a linearly-polarized [Formula: see text]GeV photon beam impinges on a hydrogen target contained within a hermetic detector with near-complete neutral and charged particle coverage. In 2016, the experiment completed its commissioning and subsequently started to take data in its design configuration. With the size of the data set so far, GlueX already exceeds previous experiments for polarized photoproduction in this energy regime. A selection of early results will be presented, focusing on beam asymmetries for pseudo-scalar and vector mesons. The potential to make significant contributions to the field of light-meson spectroscopy is highlighted by the observation of several known meson resonances. Furthermore, the strategy to map the light meson spectrum with amplitude analysis tools will be outlined.

Streszczenie:
Understanding high-order harmonic generation (HHG) from solid targets holds the key of potential technological innovations in the field of high-frequency coherent sources. Solids present optical nonlinearities at lower driving intensities, and harmonics can be efficiently emitted due to the increased electron density in comparison with the atomic and molecular counterparts. In addition, crystalline solids introduce a new complexity, as symmetries play a role in the anisotropic character of the optical response. An extraordinary playground is, therefore, the scenario in which solids are driven by vector beams, since crystal symmetries can be directly coupled with the topology of the driving laser beam. In this contribution we analyze the topological properties of the HHG radiation emitted by a single-layer graphene sheet driven by a vector beam. We show that the harmonic field is a complex combination of vortices, whose geometrical properties hold information about the details of the non-linear response of the crystal. We demonstrate, therefore, that the analysis of the topological structure of the harmonic field can be used as a spectroscopic measurement technique, paving the way of topological spectroscopy as a new strategy for the characterization of the optical response of macroscopic targets.

Streszczenie:
Kα satellite spectroscopy can be a valuable technique for diagnosing conditions in high energy density plasmas. Kα emission lines are produced in intense light ion beam plasma interaction experiments as 2p electrons fill partially open Is shells created by the ion beam. In this paper, we present results from collisional-radiative equilibrium (CRE) calculations which show how Kα emission spectroscopy can be used to determine target plasma conditions in intense lithium beam experiments on Particle Beam Fusion Accelerator-II (PBFAII) at Sandia National Laboratories. In these experiments, 8–10 MeV lithium beams with intensities of 1–2 TW/cm2 irradiate planar multilayer targets containing a thin Al tracer. Kα emission spectra are measured using an X-ray crystal spectrometer with a resolution of λ/∆λ = 1200. The spectra are analyzed using a CRE model in which multilevel (NL ∼ 103) statistical equilibrium equations are solved self-consistently with the radiation field and beam properties to determine atomic level populations. Atomic level-dependent fluorescence yields and ion-impact ionization cross sections are used in computing the emission spectra. We present results showing the sensitivity of the Kα emission spectrum to temperature and density of the Al tracer. We also discuss the dependence of measured spectra on the X-ray crystal spectral resolution, and how additional diagnostic information could be obtained using multiple tracers of similar atomic number.

Streszczenie:
Stimulated Raman scattering is a phenomenon with potential use in providing real-time molecular information in three-dimensions (3D) of a sample using imaging. For precise imaging, the knowledge about the spatial generation of stimulated Raman scattering is essential. To investigate the spatial behavior in an idealized case, computer simulations and experiments were performed. For the computer simulations, diffraction theory was used for the beam propagation complemented with nonlinear phase modulation describing the interaction between the light and matter. For the experiments, a volume of ethanol was illuminated by an expanded light beam and a plane inside the volume was imaged in transmission. For generating stimulated Raman scattering, a pump beam was focused into this volume and led to a beam dump after passing the volume. The pulse duration of the two beams were 6 ns and the pump beam energy ranged from 1 to 27 mJ. The effect of increasing pump power on the spatial distribution of the Raman gain and the spatial growth of the signal at different interaction lengths between the beam and the sample was investigated. The spatial width of the region where the stimulated Raman scattering signal was generated for experiments and simulation was 0.21 and 0.09 mm, respectively. The experimental and simulation results showed that most of the stimulated Raman scattering is generated close to the pump beam focus and the maximum peak of the Stokes intensity spatially comes shortly after the peak of the pump intensity.

Streszczenie:
Solid, powdered samples are often prepared for infrared (IR) spectroscopy analysis in the form of compressed pellets. The intense scattering of incident light by such samples inhibits applications of more advanced IR spectroscopic techniques, such as two-dimensional (2D)-IR spectroscopy. We describe here an experimental approach that enables the measurement of high-quality 2D-IR spectra from scattering pellets of zeolites, titania, and fumed silica in the OD-stretching region of the spectrum under flowing gas and variable temperature up to ∼500 ◦C. In addition to known scatter suppression techniques, such as phase cycling and polarization control, we demonstrate how a bright probe laser beam comparable in strength with the pump beam provides effective scatter suppression. The possible nonlinear signals arising from this approach are discussed and shown to be limited in consequence. In the intense focus of 2D-IR laser beams, a free-standing solid pellet may become elevated in temperature compared with its surroundings. The effects of steady state and transient laser heating effects on practical applications are discussed.

Streszczenie:
Near-infrared transmission spectroscopy (NITS) is applied to thin cotton webs to measure fiber fineness (expressed either as specific surface—the external surface area per unit weight of fiber—or as cross-sectional perimeter). We report here the development and successful testing of a mathematical model that predicts a linear relationship between fineness and light-scattering intensity (optical density, log 1/ T) by a thin cotton web. With a thin web of fibers in the light beam, absorption of photons out of the beam is negligible. When the detector is placed several inches from the web, only the photons passing between the fibers strike the light detector. Photons that strike a fiber are scattered out of the light beam and away from the detector. Thus the fineness of the fiber controls the propagation of light to the detector. The premise that specific surface is proportional to optical density when the weight of fiber in the light beam is constant is shown experimentally (probability, p < 0.0045). Also, the premise that perimeter is proportional to optical density when the total length of fiber in the light beam is constant is shown experimetally ( p < 0.0070). These results are based on analysis of 9 cottons; 810 webs were produced, computer sorted by weight, and the scatter spectra recorded for 360 webs.

Streszczenie:
Historically, two methods have been used to determine the wavelength of neutrons: (i) a timeof-flight method that separates the velocity of pulsed neutrons by the flight time; and (ii) a method utilizing Bragg reflection by a monochromator, such as a single crystal or multilayer mirror. The former cannot be applied to electromagnetic waves because the light velocity is constant and independent of the wavelength, whereas “polychromators” such as prisms and gratings, which separate wavelengths via chromatic dispersion, are typically used in the infrared to soft X-ray range. Although polychromators require collimated beams to separate wavelengths with sufficient resolution, this aspect does not affect laser and synchrotron light because they are naturally collimated. Herein, we propose a novel idea of a neutron polychromator utilizing an elliptical multilayered mirror that can be applied to a wide beam with a large beam divergence. In addition, examples of reflectometer and spectrometer applications are presented.

Streszczenie:
A highly resolving micro-light beam-induced current (µLBIC)-system is presented in this work. Based on the laser excitation via an optical microscope, current values can be measured with sub-micron precision. We show, that this non-destructive, light-based approach delivers superior results to a reference electron microscope based electron beam induced current method concerning contrast and robustness towards reflection differences, whereas no vacuum is needed, no charging effects can occur and equal resolution is achieved. µLBIC allows therefore mapping of pn-junctions at silicon solar cell cross sections. By combination of µLBIC with other measurement methods in the same setup, such as micro-Raman spectroscopy, complementary microscopic information about material stress or crystallinity and electronic properties at the same region of interest on the sample is revealed. By applying µLBIC for analyzing silicon solar cross sections, two characterization examples of current technological relevance are presented: enhanced dopant diffusion along grain boundaries between grains with different orientations is quantified and the impact of a nickel silicide spike on local charge collection quality is studied.

Streszczenie:
Halbleiter-Nanosäulen (auch -Nanodrähte) werden als Baustein für Leuchtdioden (LEDs) untersucht. Herkömmliche LEDs aus Galliumnitrid (GaN) bestehen aus mehreren Kristallschichten auf einkristallinen Substraten. Ihr Leistungsvermögen wird durch Gitterfehlpassung und dadurch hervorgerufene Verspannung, piezoelektrische Felder und Kristallfehler beschränkt. GaN-Nanosäulen können ohne Kristallfehler auf Fremdsubstraten gezüchtet werden. Verspannung wird in Nanosäulen elastisch an der Oberfläche abgebaut, dadurch werden Kristallfehler und piezoelektrische Felder reduziert. In dieser Arbeit wurden GaN-Nanosäulen durch Molukularstrahlepitaxie katalysatorfrei gezüchtet. Eine Machbarkeitsstudie über das Kristallwachstum von Halbleiter-Nanosäulen auf Metall zeigt, dass GaN-Nanosäulen in hoher Kristallqualität ohne einkristallines Substrat epitaktisch auf Titanschichten gezüchtet werden können. Für das Wachstum axialer (In,Ga)N/GaN Heterostrukturen in Nanosäulen wurden quantitative Modelle entwickelt. Die erfolgreiche Herstellung von Nanosäulen-LEDs auf Silizium-Wafern zeigt, dass dadurch eine Kontrolle der Emissionswellenlänge erreicht wird. Die Gitterverspannung der Heterostrukturen in Nanosäulen ist ungleichmäßig aufgrund des Spannungsabbaus an den Seitenwänden. Das katalysatorfreie Zuchtverfahren führt zu weiteren statistischen Schwankungen der Nanosäulendurchmesser und der Abschnittlängen. Die entstandene Zusammensetzung und Verspannung des (In,Ga)N-Mischkristalls wird durch Röntgenbeugung und resonant angeregte Ramanspektroskopie ermittelt. Infolge der Ungleichmäßigkeiten erfordert die Auswertung genaue Simulationsrechnungen. Eine einfache Näherung der mittleren Verspannung einzelner Abschnitte kann aus den genauen Rechnungen abgeleitet werden. Gezielte Verspannungseinstellung erfolgt durch die Wahl der Abschnittlängen. Die Wirksamkeit dieses allgemeingültigen Verfahrens wird durch die Bestimmung der Verspannung von (In,Ga)N-Abschnitten in GaN-Nanosäulen gezeigt.
Semiconductor nanowires are investigated as a building block for light-emitting diodes (LEDs). Conventional gallium nitride (GaN) LEDs contain several crystal films grown on single crystal substrates, and their performance is limited by strain-induced piezoelectric fields and defects arising from lattice mismatch. GaN nanowires can be obtained free of defects on foreign substrates. In nanowire heterostructures, the strain arising from lattice mismatch can relax elastically at the free surface. Crystal defects and piezoelectric fields can thus be reduced. In this thesis, GaN nanowires are synthesized in the self-induced way by molecular beam epitaxy. A proof-of-concept study for the growth of semiconductor nanowires on metal shows that GaN nanowires grow epitaxially on titanium films. GaN of high crystal quality is obtained without a single crystal substrate. Quantitative models for the growth of axial (In,Ga)N/GaN nanowire heterostructures are developed. The successful fabrication of nanowire LED devices on silicon wafers proves that these models provide control over the emission wavelength. In the (In,Ga)N/GaN nanowire heterostructures, strain is non-uniform due to elastic relaxation at the sidewalls. Additionally, the self-induced growth leads to statistical fluctuations in the diameter and length of the GaN nanowires, and in the thickness of the axial (In,Ga)N segments. The (In,Ga)N crystal composition and lattice strain are analyzed by x-ray diffraction and resonant Raman spectroscopy. Due to the non-uniformity in strain, detailed numerical simulations are required to interpret these measurements. A simple approximation for the average strain in the nanowire segments is derived from the detailed numerical calculation. Strain engineering is possible by defining the nanowire segment lengths. Simulations of resonant Raman spectra deliver the experimental strain of (In,Ga)N segments in GaN nanowires, and give a proof of this universal concept.

Streszczenie:
No presente trabalho, o peptídeo inseticida recombinante Jaburetox-2Ec, derivado da urease de Canavalia ensiformis (Jack bean) foi estudado, principalmente através de técnicas de espectroscopia de espalhamento de luz e raios-X. Foi analisada a tendência do peptídeo a se agregar em diferentes condições físico-químicas quando em solução aquosa, e a sua interação com membranas de lipossomas miméticos de plaquetas humanas. A partir dos dados de raio hidrodinâmico, raio de giro, e massa molar ponderal média obtidos do peptídeo em solução, foi possível observar uma tendência para maior agregação numa faixa em torno de pH 5,5, bem como ausência de agregação em pH inferior a 4,0 e superior a 7,0. Não se verificou nenhum efeito visível no nível de agregação com a adição de agente redutor ou íons, sendo que a exposição ao oxigênio do ar levou a um aumento da mesma. Os estudos de interação do Jaburetox-2Ec com lipossomas revelaram uma significante mudança estrutural na membrana, que se mostrou mais intensa com uma maior concentração do peptídeo. Foram, através de software, feitos ajustes teóricos das curvas de espalhamento de raios-X à baixos ângulos dos lipossomas, a fim de quantificar as mudanças nos parâmetros físicos das membranas causados pela ação do peptídeo. A formação de poros na membrana pelo peptídeo foi proposta como explicação para os resultados encontrados.
In the present work, the insecticide recombinant peptide Jaburetox-2Ec, derived from Canavalia ensiformis (Jack bean) urease, was studied, primarily by light and X-ray scattering techniques. Its tendency to aggregate in aqueous solution under different physical-chemical conditions, and its interaction with human platelet mimetic liposome membranes were analyzed. From the data relative to hydrodynamic radii, radii of gyration and mean molecular weight obtained from the peptide in aqueous solution, it was possible to observe a tendency for greater aggregation around pH 5.5, as well as an absence of aggregation at values of pH below 4.0 and above 7.0. No visible effect on the level of aggregation was verified with the addition of reducing agent or ions, whereas the exposure to oxygen in the air resulted in an increase in this level. The studies of Jaburetox-2Ec interaction with liposomes revealed a significant structural change in the membrane, which was shown to be more intense in higher peptide concentrations. Software-assisted theoretical fits were made for the experimental small-angle X-ray scattering curves aiming to quantify the changes in the physical parameters of the membranes caused by peptide action. The formation of pores in the membrane was proposed as an explanation to the results found.

Streszczenie:
AbstractAttosecond four-wave mixing spectroscopy is a relatively new technique for studying ultrafast dynamics of highly excited states with exquisite temporal precision and spectral resolution. The attosecond four-wave mixing technique, as described in this paper, uses non-collinear beam geometries of one attosecond pulse together with two optical pulses to obtain background-free, spatially isolated emission signals in the extreme ultraviolet range that directly resolve coherent dynamics in the time domain. This method is advantageous by avoiding the strong spectral modulations that often complicate the interpretation of collinear attosecond transient absorption studies while also enabling greater control over the spatial and temporal characteristics of each light-matter interaction used to probe the ultrafast processes. This paper describes a broad range of attosecond four-wave mixing experiments performed in gas phase atoms and molecules, and a recent extension into solids.

AbstractThe sampling of petahertz light fields opens up a new regime for field-resolved spectroscopy of ultrafast light-matter interactions. We derived a theoretical model tested against systematic experimental studies on the emergence of macroscopic currents in photoconductive field sampling. The model overcomes previous heuristic interpretations and can aid in the design of more sensitive and more efficient photoconductive devices. Furthermore, we implemented a near-field method for the spatio-temporal sampling of near-petahertz fields, enabling full vectorial field characterization of light beams with orbital angular momentum.

Streszczenie:
The principal means of producing muons is the collision of high energy protons with light nuclei such as carbon. Accelerator-based muon sources produce controlled beams of muons suitable for particular experiments. Surface beamlines transport muons produced when pions decay at rest. Decay beamlines transport muons produced from pions decaying in flight. Beamline components allow control of the muon beam charge, momentum, spin polarization and direction, as well as the beam size and time structure.

Streszczenie:
In many experiments involving molecular beams for fundamental studies of e.g. chemical reactions in crossed beams [1,2], so called seeded beams are used. In such a beam a few percent of the desired molecule is mixed in an excess of light driver gas. This accelerates the heavier seed molecules, and also cools the translational, rotational, and vibrational degrees of freedom of the molecules. The translational acceleration and simultaneous cooling in the beam can be studied by molecular beam techniques coupled to mass spectroscopy, like rapid mechanical chopping and molecular time-of-flight measurements. The rotational and vibrational temperatures are much harder to determined in an ordinary molecular apparatus, and some optical spectroscopic method is usually needed [3,4,5].

Video measurements of the polarized component of back scattered light show a characteristic pattern around an incident linearly polarized laser beam. This pattern can be attributed to early photons which probe only a thin superficial layer of the medium. Mie theory is used to explain the angular polarization pattern. Measurements at two wavelengths on phantoms with different particle sizes and on human skin are reported.

Streszczenie:
Early experiments to study Brownian motion of particle-fluid suspensions by laser light scattering used electronic spectrum analyzers for detection of the resulting spectral broadening. Inclusion of a local oscillator (LO) beam in such experiments improved signal strengths via the “heterodyne advantage.” However, the difficulty of wave-front matching in the heterodyne technique was emphasized from the start. In recent years, these techniques have largely been supplanted by photon correlation spectroscopy (PCS). We describe a new configuration of heterodyne/spectrum analyzer spectroscopy for the study of small ceramic particles as they form in seeded flames. In our setup, the waists of the LO and scattering beams overlap within the scattering volume, largely eliminating problems of wave-front matching. Our photodiode detector has shot-noise-limited performance for LO beams at the 50-μW level, permitting most of the laser power to be employed in the scattering beam. We discuss the relative advantages of PCS and of this heterodyne technique based on a side-by-side experimental comparison.

Streszczenie:
The Los Alamos Fourier transform spectrometer (FTS) was designed using the same principles as those of the Kitt Peak FTS.1 The Los Alamos FTS has two 8-in. cat's-eye reflectors moving on oil bearings with a travel of 1 meter for each reflector (Fig. 1). The optical path is folded to conserve space through the use of two 8-in. flat mirrors. The beam splitter is composed of two partially reflecting plates mounted one over the other. In this optical arrangement, the upper plate acts as a beam splitter and the bottom plate a beam recombiner. These plates are mounted in a turret that holds two more beam splitters and this turret can be easily rotated to select a different beam splitter. The optical arrangement allows for two light inputs and two light outputs. The two inputs are located at the end of the instrument and at the side. The two outputs are located at the front of the instrument. All important optical elements can be adjusted externally.
