Available in PDF, EPUB and Kindle. Book excerpt: Johannes Schötz presents the first measurements of optical electro-magnetic near-fields around nanostructures with subcycle-resolution. The ability to measure and understand light-matter interactions on the nanoscale is an important component for the development of light-wave-electronics, the control and steering of electron dynamics with the frequency of light, which promises a speed-up by several orders of magnitude compared to conventional electronics. The experiments presented here on metallic nanotips, widely used in experiments and applications, do not only demonstrate the feasibility of attosecond streaking as a unique tool for fundamental studies of ultrafast nanophotonics but also represent a first important step towards this goal.

Download or read book Plasmon Enhanced Photoelectron Spectroscopy and the Generation of Isolated Attosecond XUV Pulses for Use with Condensed Matter Targets written by Phillip Michael Nagel and published by . This book was released on 2011 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface plasmon resonances (SPRs), collective oscillations of quasi-free electrons in metals, can produce strong electric field enhancements at the surface of nanoparticles. These oscillations typically occur at optical frequencies (thus having a period on the order of one to a few femtoseconds) and only remain coherent for a few to tens of femtoseconds. Because of their increasing importance in various applications, it is important to understand SPRs at a fundamental level. The ultrafast nature of the processes involved with SPRs make time-resolved spectroscopy an important tool for probing their dynamics. Recently developed light sources capable of producing isolated attosecond (10-̂18 s) pulses of light can provide snapshots of electron dynamics on a sub-femtosecond timescale. Fewer than a dozen laboratories in the world currently have the ability to produce such light pulses. In this dissertation I discuss the development and construction of an experimental apparatus capable of producing and utilizing isolated attosecond pulses to study condensed matter, including surface plasmon dynamics. The ultimate goal of the experiments presented here is to laser-excite plasmonic resonances in metallic nanostructures and to detect the field enhancement at the surface of the nanostructures by measuring photoelectron spectra. In the first experiment presented, electron photoemission from lithographically prepared gold nanopillars using nominally few-cycle, 800 nm laser pulses is described. Electron kinetic energies are observed that are higher by up to tens of eV compared to photoemission from a flat gold surface at the same laser intensities. A classical electron acceleration model consisting of multiphoton ionization followed by field acceleration qualitatively reproduces the electron kinetic energy data and suggests average enhanced electric fields due to the nanopillars that are between 25 and 39 times greater than the experimentally used laser fields. In the second experiment presented, attosecond streaking from a W(110) single crystal and from an amorphous Cr thin film is demonstrated. In addition, a novel concept for SPR enhanced attosecond streaking is proposed and evaluated with the aid of a numerical model.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents the state of the art in nonlinear nanostructures for ultrafast laser applications. Most recent results in two emerging fields are presented: (i) generation of laser-induced nanostructures in materials like metals, metal oxides and semiconductors, and (ii) ultrafast excitation and energy transfer in nanoscale physical, chemical and hybrid systems. Particular emphasis is laid on the up-to-date controversially discussed mechanisms of sub-wavelength ripple formation including models of self-organized material transport and multiphoton excitation channels, nonlinear optics of plasmonic structures (nanotips, nanowires, 3D-metamaterials), and energy localization and transport on ultrafast time scale and spatial nanoscale. High-resolution spectroscopy, simulation and characterization techniques are reported. New applications of ultrashort-pulsed lasers for materials processing and the use of nanostructured materials for characterizing laser fields and laser-matter-interactions are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: This book documents the recent vivid developments in the research field of ultrashort intense light pulses for probing and controlling ultrafast dynamics. The recent fascinating results in studying and controlling ultrafast dynamics in ever more complicated systems such as (bio-)molecules and structures of meso- to macroscopic sizes on ever shorter time-scales are presented. The book is written by some of the most eminent experimental and theoretical experts in the field. It covers the new groundbreaking research directions that were opened by the availability of new light sources such as fully controlled intense laser fields with durations down to a single oscillation cycle, short-wavelength laser-driven attosecond pulses and intense X-ray pulses from the upcoming free electron lasers. These light sources allowed the investigation of dynamics in atoms, molecules, clusters, on surfaces and very recently also in nanostructures and solids in new regimes of parameters which, in turn, led to the identification of completely new dynamics and methods for controlling it. Example topics covered by this book include the study of ultrafast processes in large molecules using attosecond pulses, control of ultrafast electron dynamics in solids with shaped femtosecond laser pulses, light-driven ultrafast plasmonic processes on surfaces and in nanostructures as well as research on atomic and molecular systems under intense X-ray radiation. This book is equally helpful for people who would like to step into this field (e.g. young researchers), for whom it provides a broad introduction, as well as for already experienced researchers who may enjoy the exhaustive discussion that covers the research on essentially all currently studied objects and with all available ultrafast pulse sources.

Available in PDF, EPUB and Kindle. Book excerpt: This book represents the first detailed description, including both theoretical aspects and experimental methods, of the interaction of rare-earth ions with surface plasmon polariton from the point of view of collective plasmon-photon interactions via resonance modes (metal nanoparticles or nanostructure arrays) with quantum emitters (rare-earth ions). These interactions are of particular interest for applications to optical telecommunications, optical displays, and laser solid state technologies. Thus, our main goal is to give a more precise overview of the rapidly emerging field of nanophotonics by means of the study of the quantum properties of light interaction with matter at the nanoscale. In this way, collective plasmon-modes in a gain medium result from the interaction/coupling between a quantum emitter (created by rare-earth ions) with a metallic surface, inducing different effects such as the polarization of the metal electrons (so-called surface plasmon polariton - SPP), a field enhancement sustained by resonance coupling, or transfer of energy due to non-resonant coupling between the metallic nanostructure and the optically active surrounding medium. These effects counteract the absorption losses in the metal to enhance luminescence properties or even to control the polarization and phase of quantum emitters. The engineering of plasmons/SPP in gain media constitutes a new field in nanophotonics science with a tremendous technological potential in integrated optics/photonics at the nanoscale based on the control of quantum effects. This book will be an essential tool for scientists, engineers, and graduate and undergraduate students interested not only in a new frontier of fundamental physics, but also in the realization of nanophotonic devices for optical telecommunication.

Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, numerical models have been developed to investigate strong-field photoemission and attosecond streaking spectroscopy from plasmonic nanoparticles. Attosecond streaking spectroscopy and strong-field photoemission are powerful methods for investigating the electronic dynamics in gaseous atoms, that are currently being transferred to the investigation of collective electronic (plasmonic) effects in solids and nanostructures. First, a classical model is proposed to study plasmon excitations in metal nanoparticles using attosecond streaking spectroscopy. In this model, by sampling over classical photoelectron trajectories, we simulated streaked photoelectron energy spectra as a function of the time delay between ionizing isolated attosecond extreme ultraviolet pulses and assisting infrared or visible streaking laser pulses. Our theoretical model comprises a sequence of four steps: XUV excitation, electron transport in the nanoparticles, escape from the surface of the nanoparticles, and propagation to the photoelectron detector. Based on numerical applications to gold nanospheres, we investigated streaked photoemission spectra with regard to (i) the nanoparticle's dielectric response to the electric field of the streaking laser pulse, (ii) relative contributions of photoelectron release from different locations on and in the nanoparticle, (iii) contributions of photoemission from the Fermi level only versus emission from the entire occupied conduction band, and (iv) their fidelity in imaging the spatiotemporal distribution of the induced plasmonic field near the particle's surface. Second, based on this model, we suggest a method for reconstructing induced plasmonic fields with nm spatial and sub-fs temporal resolution from streaked photoemission spectra. Applying this imaging scheme to gold nanospheres, we demonstrated the accurate spatiotemporal reconstruction of the plasmonic near-field distribution in comparison with the directly calculated plasmonic field. Finally, strong-field photoemission from metal nanoparticles was modeled. The numerical model includes: (i) photoelectron emission on the nanoparticle surface by an intense infrared laser pulse, (ii) photoelectron propagation outside the nanosphere in the presence of the incident laser and induced plasmonic fields, and (iii) photoelectron rescattering and recombination to the nanoparticle. Based on simulated photoelectron-momentum distributions from gold nanospheres for two different intensities, and in comparison with velocity-map-image photoelectron spectra measured at the James R. Macdonald Laboratory, we scrutinize the effects of induced plasmonic fields, photoelectron correlations and electron-residual charge interactions, and photoelectron rescattering and recombination at the nanoparticle surface.
