Nonlinear Spectroscopy: The approach has been to study molecular systems which exhibit unusual spectroscopic behavior, in the hope that they may lead to novel techniques for upconverting laser frequencies. Also studied are novel methods of laser spectroscopy and wavelength stabilization. Tunable Laser and Coherent Light Techniques for High Resolution Ultraviolet Spectroscopy-10 papers produced. The overall theme of this contract has been on studies of the physics and technology of extreme ultraviolet (XUV) and soft x-ray lasers and devices. Much of the work has centered on methods for the production of core-excited metastable atoms and ions; and on the use of these atoms and ions both for new types of spectroscopy and for new types of XUV Lasers. An extensive study is made of the scattering of N2 off the flat, close-packed Ag(111) surface. Not only is the rotational population of the scattered N2, but also the alignment as described by the quadrople and hexadecapole moments of the J distribution, denoted by A(2) and sub 0 and A(4) sub 0 respectively.

Laser processing has been used in a wide variety of applications and materials such as semiconductors, superconductors, ceramics, polymers and metals. Lasers provide a controlled source of atomic and electronic excitations involving nonequilibrium phenomena that lend themselves to processing of novel materials and structures. The range of laser-solid interactions involving electronic excitation, melting and evaporation result in the formation of novel phases, selective gas excitations, surface modification and low-temperature thin-film deposition. This book from MRS focuses on the use of lasers in both the fundamental understanding and applied aspects of laser-solid and laser-gas interactions relevant to materials processing. Applications featured include thin-film transistors formed by laser-induced crystallization of amorphous silicon, diamond coatings and micromachining. Topics include: fundamentals of laser-solid interactions; fundamentals of pulsed laser ablation; pulsed laser deposition; novel applications of laser processing; laser-driven formation of nanocrystals; laser annealing; surface modification and etching; and laser-assisted chemical vapor deposition.

The laser has revolutionized many areas of science and society, providing bright and versatile light sources that transform the ways we investigate science and enables trillions of dollars of commerce. Now a second laser revolution is underway with pulsed petawatt-class lasers (1 petawatt: 1 million billion watts) that deliver nearly 100 times the total world's power concentrated into a pulse that lasts less than one-trillionth of a second. Such light sources create unique, extreme laboratory conditions that can accelerate and collide intense beams of elementary particles, drive nuclear reactions, heat matter to conditions found in stars, or even create matter out of the empty vacuum. These powerful lasers came largely from U.S. engineering, and the science and technology opportunities they enable were discussed in several previous National Academies' reports. Based on these advances, the principal research funding agencies in Europe and Asia began in the last decade to invest heavily in new facilities that will employ these high-intensity lasers for fundamental and applied science. No similar programs exist in the United States. Opportunities in Intense Ultrafast Lasers assesses the opportunities and recommends a path forward for possible U.S. investments in this area of science.

This book, now in its fourth edition, is a well-known classic on the ultrafast nonlinear and linear processes responsible for supercontinuum generation. The book begins with chapters reviewing the experimental and theoretical understanding of the field along with key applications developed since the discovery of the supercontinuum effect. The chapters that follow cover recent research activity on supercontinuum phenomena, novel applications, and advances achieved since the publication of the previous edition. The new chapters focus on: filamentation in gases, air, and condensed media; conical emission by four-wave mixing and X-waves; electronic self-phase mechanism; higher harmonics generation; attosecond laser pulses; complex vector beam supercontinuum; higher order self-phase modulation and cross-phase modulation; nonlinear supercontinuum interference in uniaxial crystals; new nonlinear microscopes involving supercontinuum and ultrafast lasers with biomedical applications; and other current supercontinuum applications in communications. The Supercontinuum Laser Source is a definitive work by one of the discoverers of the white light effect. It is indispensable reading for any researcher or student working in the field of ultrafast laser physics.

This volume presents a selection of articles based on inspiring lectures held at the “Capri” Advanced Summer School, an original event conceived and promoted by Leonida Antonio Gizzi and Ralph Assmann that focuses on novel schemes for plasma-based particle acceleration and radiation sources, and which brings together researchers from the conventional accelerator community and from the high-intensity laser-matter interaction research fields. Training in these fields is highly relevant for ultra-intense lasers and applications, which have enjoyed dramatic growth following the development of major European infrastructures like the Extreme Light Infrastructure (ELI) and the EuPRAXIA project. The articles preserve the tutorial character of the lectures and reflect the latest advances in their respective fields. The volume is mainly intended for PhD students and young researchers getting started in this area, but also for scientists from other fields who are interested in the latest developments. The content will also appeal to radiobiologists and medical physicists, as it includes contributions on potential applications of laser-based particle accelerators.

High power lasers and their applications in production technology have experienced a vivid development during the last decades and now offer improved performance of classical applications in cutting or welding. Processes that are used since a long time have been improved considerably, for instance hardening. More and more new applications have been developed for instance 3D-printing of metals or forming with laser assistance. Therefore, it is important for production engineers to understand the laser technology and explore how it can be used to enhance production speed, quality, and reduce cost. This book treats the basic principles underlying laser technology, long-time-used equipment and processes but also the most recent improvements and applications, then compares it with the competing conventional technologies. Each of these two parts is preceded by tutorials that inform the reader about the physical basis of the respective technologies. In addition, hazards of these technologies and respective protection are treated for both cases. The book concludes with a detailed comparison of competing technologies and lasers to give a prognosis on the future of lasers in manufacturing. It is written in a style that can be read by people without a broad physical basis and avoids the use of derivations and equations but explains all the material in an easily understandable way in simple words.

This book gives the readers an introduction to experimental and theoretical knowledge acquired by large-scale laser laboratories that are dealing with extra-high peak power and ultrashort laser pulses for research of terawatt (TW), petawatt (PW), or near-future exawatt (EW) laser interactions, for soft X-ray sources, for acceleration of particles, or for generation of hot dense thermal plasma for the laser fusion. The other part of this book is dealing with the small-scale laser laboratories that are using for its research on commercial sources of laser radiation, nanosecond (ns), picosecond (ps), or femtosecond (fs) laser pulses, either for basic research or for more advanced applications. This book is divided into six main sections dealing with short and ultrashort laser pulses, laser-produced soft X-ray sources, large-scale high-power laser systems, free-electron lasers, fiber-based sources of short optical pulse, and applications of short pulse lasers. In each chapter readers can find fascinating topics related to the high energy and/or short pulse laser technique. Individual chapters should serve the broad spectrum of readers of different expertise, layman, undergraduate and postgraduate students, scientists, and engineers, who may in this book find easily explained fundamentals as well as advanced principles of particular subjects related to these phenomena.
