Book Description
In the early 1970s, researchers in Canada, the Soviet Union and the United States discovered that powerful infrared laser pulses are capable of dissociating mole cules such as SiF4 and SF6' This result, which was so unexpected that for some time the phenomenon of multiple-photon dissociation was not recognized in many cir cumstances in which we now know that it occurs, was first publicized at a time when the possibility of using lasers for the separation of isotopes had attracted much attention in the scientific community. From the mid-1970s to the early 1980s, hun dreds of experimental papers were published describing the multiple-photon absorp tion of C02 laser pulses in nearly every simple molecule with an absorption band in the 9 - 11 jJm region. Despite this impressive volume of experimental results, and despite the efforts of numerous theorists, there is no agreement among re searchers in the field on many fundamental aspects of the absorption of infrared laser light by polyatomic molecules. This book is devoted to reviells of the experimental and theoretical research that provides the foundations for our current understanding of molecular multiple photon exc itat i on, and to rev i ews of research that is pert i nent to the 1 aser sep aration of isotopes.

Book Description
Laser Stimulated Scattering and Multiphoton Excitation is the first book to comprehensively cover quantum electrodynamic theory of stimulated scattering and multiphoton excitation processes, as well as various stimulated scattering effects. These include stimulated Raman scattering (SRS) and stimulated Brillouin scattering (SBS), as well as more recent advances in the field such as stimulated Kerr scattering (SKS), stimulated Rayleigh-Bragg scattering (SRBS) and stimulated Mie scattering (SMS). The book goes on to discuss multiphoton excitation-based nonlinear optical effects, photoelectric effects, atomic and molecular ionization effects, and molecular dissociation effects. Each chapter includes a description of the key concepts and mechanisms alongside the necessary theoretical formulations, as well as engaging with the latest experimental research achievements and the scientific and technological applications. Laser Stimulated Scattering and Multiphoton Excitation is essential reading for academics, research scientists, and students working or interested in the areas of nonlinear optics, nonlinear photonics, laser spectroscopy, physical optics, physical chemistry, and optoelectronic engineering.

Book Description
Prefaces are usually written when a manuscript is finished. Having finished this book I can clearly see many shortcomings in it. But if I began to eliminate them I would probably write quite a different book in another two years; indeed, this has already happened once. In 1979, when I finished the first version of this book, it was much broader in scope and was to be titled "Laser Photochemistry." Corrections and additions to that unpublished manuscript gave rise to the present book with its revised title and more specific subject matter. I resolved to have it published in exactly this form, despite the fact that it concerns a dynamically developing field of research and will soon make way for other works. This book contains the basic ideas and results I have been developing with my colleagues, friends and students at the Institute of Spectroscopy, USSR Academy of Sciences, in the town of Troitsk since 1970. It deals with the interaction of light with atoms and molecules via multiple-phonon inter action. Nonlinear processes in the resonant interaction are used to illustrate the physical mechanisms involved and to indicate how these processes have led to modern applications such as isotope separation, detection of single atoms and molecules, and chemical and biochemical synthesis.

Book Description
This selection of papers in the field of nonlinear optics contains reprints of original research, and general reviews written since 1960 up to the present. Brief comments by the author place each paper in a historical context of the evolution of nonlinear optics. Papers are selected from a more comprehensive bibliography either on the basis of their influence on subsequent developments or because they were originally published in journals or conference proceedings which are less easily accessible.

Book Description
The series Topics in Current Chemistry presents critical reviews of the present and future trends in modern chemical research. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field. Review articles for the individual volumes are invited by the volume editors. Readership: research chemists at universities or in industry, graduate students.

Book Description
The possibility of initiating chemical reactions by high-intensity laser exci tation has captured the imagination of chemists and physicists as well as of industrial scientists and the scientifically informed public in general ever since the laser first became available. Initially, great hopes were held that laser-induced chemistry would revolutionize synthetic chemistry, making possible "bond-specific" or "mode-specific" reactions that were impos sible to achieve under thermal equilibrium conditions. Indeed, some of the early work in this area, typically employing high-power continuous-wave sources, was interpreted in just this way. With further investigation, however, a more conservative picture has emerged, with the laser taking its place as one of a number of available methods for initiation of high-energy chemical transformations. Unlike a number of these methods, such as flash photolysis, shock tubes, and electron-beam radiolysis, the laser is capable of a high degree of spatial and molecular localization of deposited energy, which in turn is reflected in such applications as isotope enrichment or localized surface treatments. The use of lasers to initiate chemical processes has led to the discovery of several distinctly new molecular phenomena, foremost among which is that of multiple-photon excitation and dissociation of polyatomic molecules. This research area has received the greatest attention thus far and forms the focus of the present volume.

Book Description
This volume contains the lectures and communications presented at the NATO Advanced Research Workshop on "Atomic and Molecular Processes with Short Intense Laser Pulses" (NATO ARW 848/86). The workshop was held at Bishop's University, Lennoxville, Que, Canada, July 19-24, 1987, under the directorship of Prof. A.D. Bandrauk, Universite de Sherbrooke. A scientific committee made up of Dr. P. Corkum (Laser Physics, ~ational Research Council of Canada), Dr. P. Hackett (Laser Chemistry, National Research Council of Canada), Prof. S.C. Wallace (Dept. of Chemistry and Physics, University of Toronto), and Prof. F.H.M. Faisal (FakultHt fUr Physik, UniversitHt Bellefeld) was called upon to invite and organize eminent lectures in the fields of i) Coherence Phenomena in Atomic and Molecular Photoprocesses. ii) High Intensity Atomic and Molecular Phenomena. iii) Laser Chemistry The aim of the workshop was to bring together chemists and physicists in order to~iscuss and analyze the progress made in the use of short in tense laser pulses in understanding coherence phenomena and high intensity, nonlin~adiative effects in atomic and molecular systems.
