The present collection of articles sets forth the results of experimental research on physical processes in various types of optical quantum devices (lasers). Data are presented on the regulation of the temporal and spectral characteristics of solid-state lasers using a bleachable filter. A mode self-locking state is realized in which ultraflhort light pulses are emitted. The stimulated emission in a pinch discharge due to transitions of singly and doubly ion ized argon atoms in the visible and ultraviolet parts of the spectrum is investigated. Pulsed lasing associated with electron transitions in diatomic molecules at the leading edge of a power ful current pulse in a gas is subjected to systematic analysis. The book is aimed at a broad spectrum of scientists and engineers specializing in quan tum radiophysics.

By the end of the 1970s, crystalline lasers were widely used in science, engineering, medicine, and technology. The types of lasers used have continued to grow in number to include newly discovered crystalline hosts, previously known compounds generating at other spectral wavelengths, and broadband tunable stimulated emission. This has led to the creation of an extremely promising new generation of crystalline lasers that are both highly efficient and more reliable. The major part of this book is devoted to describing multilevel operating laser schemes for stimulated emission excitation in insulating crystals doped with lanthanide ions. The first part of Crystalline Lasers deals with the history of the physics and spectroscopy of insulating laser crystals. The chapters in the second part of the book present results from the study of Stark-energy levels of generating ions in laser crystals and their radiative and nonradiative intermanifold transition characteristics. This section includes extensive tabular data and reference information. Popular and novel operating schemes of crystalline lasers are covered in Part 3. In the chapters in the fourth part of the book, the newest technologies in the physics and engineering of crystalline lasers are considered. The results of investigations into laser action under selective excitations, miniature crystalline lasers, and the properties of nonlinear activated laser crystals are presented and analyzed. Crystalline Lasers summarizes and reviews the results of many years of research and studies of activator ions and multilevel operating laser schemes, and discusses exciting prospects of using these systems to create new types of crystalline lasers. This book will be of use to laser scientists and engineers, physicists, and chemical engineers.

This convenient source of reference analyzes spectro-physical properties in activated insulating laser crystals and systematizes mechanisms for obtaining stimulated emission based on these properties. Tabulations of the most important spectroscopic and pumping parameter data for insulating laser materials and the wavelengths of stimulated emission from activated insulating laser crystals permit selection of the active medium for a specific application. In addition, the book discusses the fundamental properties responsible for laser phenomena in activated crystals and a number of spectroscopic methods devised to investigate these processes. Thus it can also serve as an introduction to the physics of laser crystals and to the stimulated emission spectroscopy of activated crystals. The second edition contains updated data in the tables and more recent literature references.

It is a pleasure to write a few words as an introduction to the proceedings of the 1980 NATO ASI on "Physical Processes in Laser Naterial Interaction." This ASI is the ninth course of a series devoted to lasers and their applications, held under the responsibility of the Quantum Electronics Division of the European Physical Society, and for this reason known as the "Europhysics School of Quantum Electronics." Since 1971 the School has been operating with the joint direc tion of myself as representative of the academic research, and Dr. D. Roess (formerly with Siemens AEG, Munich, and now with Sick, Optik und Electronik, GmbH, Munich) for the industrial applications. Indeed the aim of the School is to alternate fundamental and applied frontier topics in the area of quantum electronics and modern optics, in order to introduce young research people from universities and industrial R&D laboratories to the new aspects of research opened by the laser.

During the last ten to fifteen years, researchers have made considerable progress in the study of inorganic scintillators. New scintillation materials have been investigated, novel scintillation mechanisms have been discovered, and additional scintillator applications have appeared. Demand continues for new and improved scintillation materials for a variety of applications including nuclear and high energy physics, astrophysics, medical imaging, geophysical exploration, radiation detection, and many other fields. However, until now there have been no books available that address in detail the complex scintillation processes associated with these new developments. Now, a world leader in the theory and applications of scintillation processes integrates the latest scientific advances of scintillation into a new work, Physical Processes in Inorganic Scintillators. Written by distinguished researcher Piotr Rodnyi, this volume explores this challenging subject, explains the complexities of scintillation from a modern point of view, and illuminates the way to the development of better scintillation materials. This unique work first defines the fundamental physical processes underlying scintillation and governing the primary scintillation characteristics of light output, decay time, emission spectrum, and radiation hardness. The book then discusses the complicated mechanisms of energy conversion and transformation in inorganic scintillators. The section on the role of defects in energy transfer and scintillation efficiency will be of special interest. Throughout, the author does not offer complicated derivations of equations but, instead, presents useful equations with practical results.
