Strong laser fields are essential for exploring laser-atom dynamics in modern physics. High-order harmonic generation (HHG) represents a prominent strong-field process in which an ionized electron accelerates with the electric field of an incident laser and subsequently recombines with its parent ion. The accelerated electron eventually emits a photon within the recombination process, which yields high-order harmonic radiation at the macroscopic scale. Recent advances in laser technology enable the generation of intense mid-infrared laser fields. These new laser sources extended the parameter range of HHG significantly toward the weakly relativistic regime in which the magnetic field of the incident laser field contributes to the process. This dissertation provides a theoretical model of HHG, which is a formal extension of the well-known strong-field approximation toward the weakly relativistic regime. Generally, the model considers arbitrarily spatially structured light fields, in contrast to current approaches, and therefore provides the opportunity to investigate twisted light beams within the weakly relativistic regime. The developed model explicitly considers an elliptically polarized plane wave laser beam as an example. In addition, more sophisticated laser fields are considered and briefly discussed afterward. In addition, this dissertation investigates phase matching in the context of HHG, which is afflicted with a low conversion efficiency of less than 0.1 %. Finding suitable sets of external parameters under which the conversion efficiency is respectively high is therefore of substantial interest to the strong-field community. An analytic expression of the critical intensity is derived that fulfills the phase-matching condition for an arbitrary set of initial parameters. The approach is limited to hydrogen-like noble gases and linearly polarized Gaussian laser pulses with arbitrary laser field parameters that incorporate the commonly utilized configurations. The analytical error compared to numerical computations is less than 1 %, while the computation time improves by four to six orders of magnitude.

'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.

X-Ray Lasers 2004 comprises invited, contributed, and poster papers presented at the 9th International Conference on X-Ray Lasers (ICXRL2004) held in Beijing in May 2004. Some 120 participants from 13 countries and regions met in Beijing to compare results and exchange views on future developments in x-ray lasers and related fields. The book covers the following topics: overviews of x-ray lasers research, collisionally pumped x-ray lasers, capillary discharge-pumped x-ray lasers, OFI and photo-pumped x-ray lasers, high-order harmonics XUV radiation, grazing incidence pumping x-ray lasers, theory and simulations of x-ray lasers and plasma media, free-electron lasers and accelerator-based x-ray sources, alternative pumping schemes for x-ray lasers, applications of x-ray lasers and other bright x-ray sources, x-ray optics and instrumentation, investigations of x-ray laser media, and developments of x-ray laser drivers. X-Ray Lasers 2004 provides not only an overview and an up-to-date progress report on this fast moving field, but also important reference material on which future work can be built.

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.
