This book gathers together a range of similar problems that can be encountered in different fields of modern quantum physics and that have common features with regard to multilevel quantum systems. The main motivation was to examine from a uniform standpoint various models and approaches that have been developed in atomic, molecular, condensed matter, chemical, laser and nuclear physics in various contexts. The book should help senior-level undergraduate, graduate students and researchers putting particular problems in these fields into a broader scientific context and thereby taking...

This up-to-date text deals with the mutual interaction and energy transfer between electronic defect states of F centres and defect ions and neighbouring molecular defects in alkali halides. It includes more than 100 illustrations and figures, plus many previously unpublished results.

This book presents recent and important developments in the field of terahertz radiation, with a particular focus on pulsed terahertz radiation. Situated in the gap between electronics and optics, the terahertz frequency range of the electro-magnetic spectrum has long been neglected by scientists and engineers due to a lack of efficient and affordable terahertz sources and detectors. The advent of femtosecond lasers in the 1980s and photoconductive switches in 1984 have made the terahertz gap accessible, while at the same time advances in electronics and optics have made it narrower....

Femtosecond technology, with its ultrashort light pulses, forms an innovative laser technology which can be used for multiple technical applications. The book gives a comprehensive overview of the principles and applications of femtosecond lasers, especially applied to medicine and to production technology. The principles and features of such femtosecond technology are described. The lasers, systems and technologies that are required in these potential fields of application are investigated. The advantages and problems of ultrashort laser pulses are discussed in more detail in the context...

Aimed at researchers and graduate students, this book provides up-to-date information about the electronic interactions that impact the optical properties of rare earth ions in solids. Its goal is to establish a connection between fundamental principles and the materials properties of rare-earth activated luminescent and laser optical materials. The theoretical survey and introduction to spectroscopic properties covers electronic energy level structure, intensities of optical transitions, ion-phonon interactions, line broadening, and energy transfer and up-conversion. An important aspect...

The three volumes VIII/1A, B, C document the state of the art of laser physics and applications. According to the actual trends in laser research and development, Vol. VIII/1 is split into three parts: Vol. VIII/1A with its two sub-volumes 1A1 and 1A2 covers laser fundamentals, Vol. VIII/1B deals with laser systems and Vol. VIII/1C gives an overview on laser applications.

This volume presents a coherent and detailed description of the field, and brings together leaders in theoretical research. The book discusses today's state-of-the-art, as well as tomorrow s tools: the supercell-pseudopotential method, the GW formalism, Quantum Monte Carlo, learn-on-the-fly molecular dynamics, finite-temperature treatments and more. A wealth of applications are included, from point defects to wafer bonding or the propagation of dislocation. "

A fascinating insight into the state-of-the-art in silicon microphotonics and on what we can expect in the near future. The book presents an overview of the current understanding of getting light from silicon. It concentrates mainly on low dimensional silicon structures, like quantum dots, wires and wells, but covers also alternative approaches like porous silicon and the doping of silicon with rare-earths. The emphasis is on the experimental and theoretical achievements concerning the optoelectronic properties of confined silicon structures obtained during recent years. Silicon based...

Nonlinearities and optics, optoelectronics and fiber communications are discussed systematically in this book. In a unified theoretical treatment, the book addresses the three categories of materials: fibers, semiconductors, and nonlinear crystals. In each case emphasis is placed on the nonlinear character of their refractive indices and optical absorption. The text also gives an in-depth analysis of the uses and limitations of phontonic nonlinearities with regard to wavelength division multiplexing and high-speed fiber communications. It will be of interest to graduate students as well as...
