Available in PDF, EPUB and Kindle. Book excerpt: The light source that has revolutionized attosecond science over the last decades is based on the process of high-harmonic generation (HHG), which is a unique method to generate a broadband coherent spectrum extending into the extreme-ultraviolet (XUV) range. The temporal and spatial resolution of HHG enables investigation of strong-field light-matter interaction in the ultrafast and ultrasmall dimensions, and finds applications in attosecond science, lensless imaging, and industrial metrology. Unfortunately, the intrinsic low conversion efficiency of HHG and the limited methods to control the generated XUV wavefront, slow down present research and future development of applications that are based on HHG. Control over the HHG process is essential to improve the conversion efficiency and XUV wavefront characteristics, in order to facilitate next-generation attosecond science and metrology. This thesis presents experimental techniques and results that demonstrate control over both gas-based and solid-based HHG in the extreme-ultraviolet regime. Additionally, the underlying mechanism and working principles are explained through theoretical models and simulations. In Chapter 4, we demonstrate divergence and yield optimization in polarization controlled two-color gas-based HHG. Imaging, spectroscopy, and metrology applications using HHG sources require high XUV brightness, related to the conversion efficiency and the focusability of the generated XUV pulses. We systematically investigate, both experimentally and theoretically, the effect of the relative polarization between the fundamental and its second harmonic in two-color HHG, and compare the results to a one-color configuration. In a perpendicular two-color field, the relative phase between the two colors can be used to manipulate the long or the short trajectories, allowing control over the divergence of the harmonics.

Download or read book Electron Dynamics in Solids Studied by Attosecond Extreme Ultraviolet Spectroscopy written by Lauren J. Borja and published by . This book was released on 2016 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: The creation of attosecond pulses using high harmonic generation (HHG) to produce extreme ultraviolet light (XUV) pulses has enabled table-top core-level spectroscopy in both the gas and solid phase. Because HHG relies on a near infrared (NIR) driver pulse to create the XUV radiation, it is readily incorporated into pump-probe transient absorption and photoelectron spectroscopy experiments, giving way to measurements with unprecedented temporal resolution. The ability of attosecond XUV pump-probe spectroscopy to study solid state semiconductor materials allows for the interrogation of carriers on the timescales where a separation between electronic and lattice dynamics can occur. This will have far reaching implications addressing the fundamental carrier physics that govern the next generation of hot carrier charge transfer devices, which are at the forefront of photocatalytic and electronic device development. In this dissertation, a literature review of XUV transient absorption on solids using HHG is presented in Chapter 1. This chapter details the progress from femtosecond experiments on metal-oxide thin films to attosecond time-resolved experiments on semiconductors. In Chapter 2, the design and construction of the attosecond transient absorption apparatus capable of studying ultrafast dynamics in both solid state and gas phase samples using a near infrared (NIR) pump and an extreme ultraviolet (XUV) probe is presented. Chapter 3 presents transient absorption experiments done on germanium thin films, which measure both electrons and hole dynamics simultaneously in a single measurement. These results are supported by work from a theory collaboration. in Chapter 4, preliminary work on silicon germanium alloys is presented. While the results need further confirmation by additional experiments and characterization, it is clear that signals from hot carrier relaxation are present. Chapter 5 presents a theoretical investigation of a future experiment on silver nanoparticles using a velocity map imaging (VMI) device. The key feature of this theoretical study is the identification of a metric to follow the near-field of the plasmon, isolated from the electric field of the exciting laser pulse.

Available in PDF, EPUB and Kindle. Book excerpt: 'High-order harmonics emerging from the interaction of strong laser fields with solid matter constitute a novel, highly sensitive tool for interrogating electronic structure and dynamics in solids. At the interface of attosecond physics and condensed matter physics, this book provides an excellent overview of the current state of the art.'Ferenc KrauszNobel Laureate in Physics, 2023High-order harmonic generation (HHG) in solids, the nonlinear upconversion of coherent radiation resulting from the interaction of a strong and short laser pulse with bulk matter, has come of age. Since the seminal experiments and theoretical developments, there has been a constant and vibrant interest in this topic. In this book, we invite experimental and theoretical experts in the field with the aim to summarize the progress made so far and propose new possibilities and prospects for the generation of high-order harmonics using solid samples. Nowadays, it is possible to engineer, both spatially and temporally with nanometric and attosecond resolution, the driven fields. This could bring solid HHG to the next exciting frontier as novel and fully tunable table-top coherent sources.

Available in PDF, EPUB and Kindle. Book excerpt: Following the birth of the laser in 1960, the field of "nonlinear optics" rapidly emerged. Today, laser intensities and pulse durations are readily available, for which the concepts and approximations of traditional nonlinear optics no longer apply. In this regime of "extreme nonlinear optics," a large variety of novel and unusual effects arise, for example frequency doubling in inversion symmetric materials or high-harmonic generation in gases, which can lead to attosecond electromagnetic pulses or pulse trains. Other examples of "extreme nonlinear optics" cover diverse areas such as solid-state physics, atomic physics, relativistic free electrons in a vacuum and even the vacuum itself. This book starts with an introduction to the field based primarily on extensions of two famous textbook examples, namely the Lorentz oscillator model and the Drude model. Here the level of sophistication should be accessible to any undergraduate physics student. Many graphical illustrations and examples are given. The following chapters gradually guide the student towards the current "state of the art" and provide a comprehensive overview of the field. Every chapter is accompanied by exercises to deepen the reader's understanding of important topics, with detailed solutions at the end of the book.

Download or read book Bright High-repetition-rate Source of Narrowband Extreme-ultraviolet Harmonics Beyond 22 EV. written by and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Novel table-top sources of extreme-ultraviolet light based on high-harmonic generation yield unique insight into the fundamental properties of molecules, nanomaterials or correlated solids, and enable advanced applications in imaging or metrology. Extending high-harmonic generation to high repetition rates portends great experimental benefits, yet efficient extreme-ultraviolet conversion of correspondingly weak driving pulses is challenging. In this article, we demonstrate a highly-efficient source of femtosecond extreme-ultraviolet pulses at 50-kHz repetition rate, utilizing the ultraviolet second-harmonic focused tightly into Kr gas. In this cascaded scheme, a photon flux beyond ≈3 × 1013 s-1 is generated at 22.3 eV, with 5 × 10-5 conversion efficiency that surpasses similar harmonics directly driven by the fundamental by two orders-of-magnitude. The enhancement arises from both wavelength scaling of the atomic dipole and improved spatio-temporal phase matching, confirmed by simulations. Finally, spectral isolation of a single 72-meV-wide harmonic renders this bright, 50-kHz extreme-ultraviolet source a powerful tool for ultrafast photoemission, nanoscale imaging and other applications.

This book was released on 2012-12-06 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent developement of high power lasers, delivering femtosecond pulses of 20 2 intensities up to 10 W/cm , has led to the discovery of new phenomena in laser interactions with matter. At these enormous laser intensities, atoms, and molecules are exposed to extreme conditions and new phenomena occur, such as the very rapid multi photon ionization of atomic systems, the emission by these systems of very high order harmonics of the exciting laser light, the Coulomb explosion of molecules, and the acceleration of electrons close to the velocity of light. These phenomena generate new behaviour of bulk matter in intense laser fields, with great potential for wide ranging applications which include the study of ultra-fast processes, the development of high-frequency lasers, and the investigation of the properties of plasmas and condensed matter under extreme conditions of temperature and pressure. In particular, the concept of the "fast ignitor" approach to inertial confinement fusion (ICF) has been proposed, which is based on the separation of the compression and the ignition phases in laser-driven ICF. The aim of this course on "Atom, Solids and Plasmas in Super-Intense Laser fields" was to bring together senior researchers and students in atomic and molecular physics, laser physics, condensed matter and plasma physics, in order to review recent developments in high-intensity laser-matter interactions. The course was held at the Ettore Majorana International Centre for Scientific Culture in Erice from July 8 to July 14,2000.
