Nitride Phosphors and Solid-State Lighting provides an in-depth introduction to the crystal chemistry, synthesis, luminescence, and applications of phosphor materials for solid-state lighting, mainly focusing on new nitride phosphors. Drawing on their extensive experimental work, the authors offer a multidisciplinary study of phosphor materials that encompasses materials science, inorganic chemistry, solid-state chemistry, solid-state physics, optical spectroscopy, crystal field theory, and computational materials science. The book begins with an introduction to the principles, semiconductor/phosphor materials, and characterizations of solid-state lighting and white light-emitting diodes (LEDs). It then discusses the optical and luminescence processes occurring in optically active centers of solid materials and presents the photoluminescence properties of traditional phosphors for white LEDs, including garnets, aluminates, silicates, sulfides, oxysulfides, phosphates, and scheelites. The remainder of the text focuses on newly developed nitride phosphors. The authors describe the crystal chemistry of general nitride compounds, the crystal structure and photoluminescence properties of new nitride phosphors, and synthetic methods for preparing nitride phosphors. They detail the structural analysis of nitride phosphors and present experimental and computational results of typical nitride phosphors. The authors also examine key issues, such as excitation and emission spectra, thermal quenching, and quantum efficiency. The final chapter explores applications of nitride phosphors in white LEDs for general lighting and LCD backlight purposes. Covering novel luminescent materials, this book brings you up to date on the evolving field of solid-state lighting. It illustrates the fundamentals, synthesis, properties, and applications of the latest nitride phosphor materials.

Beam is the story of the race to make the laser, the three intense years from the birth of the laser idea to its breakthrough demonstration in a California laboratory. The quest was a struggle against physics, established wisdom, and the establishment itself. In 1954, Charles Townes invented the laser's microwave cousin, the maser. The next logical step was to extend the same physical principles to the shorter wavelengths of light, but the idea did not catch fire until October 1957, when Townes asked Gordon Gould about Gould's research on using light to excite thallium atoms. Each took the idea and ran with it. The independent-minded Gould sought the fortune of an independent inventor; the professorial Townes sought the fame of scientific recognition. Townes enlisted the help of his brother-in-law, Arthur Schawlow, and got Bell Labs into the race. Gould turned his ideas into a patent borth ation and a million-dollar defense contract. They soon had company. Ali Javan, one of Townes's former students, began pulling 90-hour weeks at Bell Labs with colleague Bill Bennett. And far away in California a bright young physicist named Ted Maiman became a very dark horse in the race. While Schawlow proclaimed that ruby could never make a laser, Maiman slowly convinced himself it would. As others struggled with recalcitrant equipment and military secrecy, Maiman built a tiny and elegant device that fit in the palm of his hand. His ruby laser worked the first time he tried it, on May 16, 1960, but afterwards he had to battle for acceptance as the man who made the first laser. Beam is a fascinating tale of a remarkable and powerful invention that has become a symbol of modern technology.

Among the many atomic/molecular assembling techniques used to develop artificial materials, molecular layer deposition (MLD) continues to receive special attention as the next-generation growth technique for organic thin-film materials used in photonics and electronics. Thin-Film Organic Photonics: Molecular Layer Deposition and Applications describes how photonic/electronic properties of thin films can be improved through MLD, which enables precise control of atomic and molecular arrangements to construct a wire network that achieves "three-dimensional growth." MLD facilitates dot-by-dot -- or molecule-by-molecule -- growth of polymer and molecular wires, and that enhanced level of control creates numerous application possibilities. Explores the wide range of MLD applications in solar energy and optics, as well as proposed uses in biomedical photonics This book addresses the prospects for artificial materials with atomic/molecular-level tailored structures, especially those featuring MLD and conjugated polymers with multiple quantum dots (MQDs), or polymer MQDs. In particular, the author focuses on the application of artificial organic thin films to: * Photonics/electronics, particularly in optical interconnects used in computers * Optical switching and solar energy conversion systems * Bio/ medical photonics, such as photodynamic therapy * Organic photonic materials, devices, and integration processes With its clear and concise presentation, this book demonstrates exactly how MLD enables electron wavefunction control, thereby improving material performance and generating new photonic/electronic phenomena.

Lasers are employed throughout science and technology, in fundamental research, the remote sensing of atmospheric gases or pollutants, communications, medical diagnostics and therapies, and the manufacturing of microelectronic devices. Understanding the principles of their operation, which underlie all of these areas, is essential for a modern scientific education. This text introduces the characteristics and operation of lasers through laboratory experiments designed for the undergraduate curricula in Chemistry and Physics. Introductory chapters describe the properties of light, the history of laser invention, the atomic, molecular and optical principles behind how lasers work, and the kinds of lasers available today. Other chapters include the basic theory of spectroscopy and computational chemistry used to interpret laser experiments. Experiments range from simple in-class demonstrations to more elaborate configurations for advanced students. Each chapter has historical and theoretical background, as well as options suggested for variations on the prescribed experiments. The text will be useful for undergraduates students in advanced lab classes, for instructors designing these classes, or for graduate students beginning a career in laser science.

Introduction to Laser Science and Engineering provides a modern resource for a first course in lasers for both students and professionals. Starting from simple descriptions, this text builds upon them to give a detailed modern physical understanding of the concepts behind light, optical beams and lasers. The coverage starts with the nature of light and the principles of photon absorption and transmission, leading to the amplified and stimulated emission principals governing lasers. The specifics of lasers and their application, safe use and future prospects are then covered, with a wealth of illustrations to provide readers with a visual sense of optical and laser principles.

Faseroptische Komponenten und Systeme sind heute unverzichtbar im Bereich der Datenubertragung, der Sensorik und Messtechnik, der Materialbearbeitung und in der Medizintechnik. Bei hohen Lichtleistungen in Glasfasern mit kleinen Querschnitten treten dabei nichtlineare optische Effekte auf, die in einigen Anwendungen gezielt genutzt werden konnen, aber in anderen Fallen storend sind.

Aufbauend auf den Grundlagen der linearen Ausbreitung von Lichtwellen in Glasfasern werden in diesem Buch die nichtlinearen faseroptischen Effekte grundlegend und systematisch behandelt. Schwerpunkte sind dabei die Auswirkungen und Anwendungen der stimulierten Raman- und Brillouin-Streuung. Spezielle Aspekte der nichtlinearen Faseroptik werden am Beispiel der Raman-Faserlaser vertieft.

Das Buch zeichnet sich durch fundierte theoretische Grundlagen, Angabe reprasentativer Zahlenwerte und anschauliche Beispiele aus. In kurzen Exkursen werden Zusammenhange aufgezeigt und weiterfuhrende Informationen gegeben. Zahlreiche Literaturangaben ermoglichen eine selbststandige weitere Vertiefung in einzelne Themen."

A comprehensive treatment of the fundamentals of optical detection theory

Laser system applications are becoming more numerous, particularly in the fields of communications and remote sensing. Filling a significant gap in the literature, Optical Detection Theory for Laser Applications addresses the theoretical aspects of optical detection and associated phenomenologies, describing the fundamental optical, statistical, and mathematical principles of the modern laser system.

The book is especially valuable for its extensive treatment of direct detection statistics, which has no analog in radar detection theory and which has never before been compiled in a cohesive manner in a single book. Coverage includes:

• A review of mathematical statistics and statistical decision theory
• Performance of truncated and untruncated coherent and direct detection systems using Huygens-Fresnel and Gaussian beam theories
• Rough surface scatter and atmospheric propagation effects
• Single-pulse detection statistics for direct and coherent detection systems
• Multi-pulse detection statistics for direct and coherent detection systems

Supported by additional comments providing further insights into the physics or mathematics discussed and an extensive list of classic references, Optical Detection Theory for Laser Applications comprises a much-needed reference for the professional scientist or engineer, as well as a solid textbook for advanced students.

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.

Readers will learn in which ways light can be "confined" within a subwavelength region smaller than half a wavelength. Strictly within the focal spot, all degrees of freedom of light interact and manifest themselves in a dramatic way. The size and shape of the focal spot and the magnitude of side-lobes depend on the polarization state alongside phase and amplitude distributions of a light beam. Readers will learn techniques in which inhomogeneously (i.e., azimuthally and radially) polarized optical beams can be focused. In sharp focus, exotic phenomena can occur, including the negative propagation of light and a toroidal optical flow. Throughout the book, the numerical simulation is performed using the rigorous solution of Maxwell's equations based on a Finite-Difference Time-Domain (FDTD) approach, which makes the results of modeling highly reliable. The photonic components, including optical metasurfaces, discussed in the book have been implemented using state-of-the-art techniques of electron beam writing and reactive ion-beam etching of microrelief. Two chapters are concerned with photonics hot spots, which deal with the control of light by means of optical metasurfaces and the generation of an energy backflow in the region of sharp focus of a laser beam. Another hot topic is diffractive polarization converters implemented as subwavelength diffraction gratings to convert polarization of light. By way of illustration, such converters are shown to perform linear-to-radial or linear-to-azimuthal polarization conversion. The book describes advanced photonic components fabricated by the authors to perform sharp focusing of light, including binary zone plates, binary axicons, a planar photonic crystal lens, diffraction polarization converters, and metalenses. This book is a must-have for individuals and institutions studying cutting edge optics.

Physics of laser crystals has been constantly developing since the invention of the laser in 1960. Nowadays, more than 1500 wide-band-gap and semiconductors crystals are suitable for the production of the laser effect. Different laser devices are widely used in science, medicine and communication systems according to the progress achieved in the development of laser crystal physics. Scintillators for radiation detection also gained benefit from these developments. Most of the optically active materials offer laser radiations within the 500 to 3000 nm region with various quantum efficiency which fit the usual applications. However, new crystals for laser emissions are needed either in the blue, UV and VUV - region or far IR- region, especially for medicine, computer microchip production and for undiscovered practical uses. Scientific problems of the growth and properties of laser crystals are discussed in numerous books and scientific journals by many scientists working in the field. Therefore, we thought that joint discussions of the scientific and technical problems in laser physics will be useful for further developments in this area. We have proposed to held a Workshop on Physics of Laser Crystals for attempting to induce additional advances especially in solid state spectroscopy. This NATO Advanced Research Workshop (ARW) was hold in Kharkiv * Stary Saltov th nd (Ukraine) on august 26 - September 2 , 2002, and was mainly devoted to the consideration 0 f modem approaches and Iast results in physics of laser crystals.

Metal vapour ion lasers are a mature class of gas laser for which a number of applications has developed in recent years. This is the first book to appear in the English language on this topic, and concentrates on the physical processes which occur in the laser, in particular the kinetic processes which are responsible for the pumping of excited ion levels, and the production of population inversion. The most important types of electrical discharges used in this class of laser are discussed in detail, and all the major types of metal vapour ion laser are examined. A highly useful appendix tabulates all the known transitions used in metal vapour ion lasers. Metal Vapour Ion Lasers: Kinetic Processes and Gas Discharges provides a much needed review of this important field. It identifies current problem areas, and points to future research directions. It is an invaluable source for all those, both in industry and academia, working on the development or applications of metal vapour ion lasers, and for all those involved in gas laser research. It will also be of great interest to all those interested in the physics of gas discharges. The authors and translators have been involved with some of the key advances in the field over recent years.

Silicon, the leading material in microelectronics during the last four decades, also promises to be the key material in the future. Despite many claims that silicon technology has reached fundamental limits, the performance of silicon microelectronics continues to improve steadily. The same holds for almost all the applications for which Si was considered to be unsuitable. The main exception to this positive trend is the silicon laser, which has not been demonstrated to date. The main reason for this comes from a fundamental limitation related to the indirect nature of the Si band-gap. In the recent past, many different approaches have been taken to achieve this goal: dislocated silicon, extremely pure silicon, silicon nanocrystals, porous silicon, Er doped Si-Ge, SiGe alloys and multiquantum wells, SiGe quantum dots, SiGe quantum cascade structures, shallow impurity centers in silicon and Er doped silicon. All of these are abundantly illustrated in the present book.

This book presents the first comprehensive collection of solved problems in laser physics covering both fundamental and applied aspects of laser science and technology. The framework of the book, including structuring of topics and notations, closely follows that adopted in the Principles of Laser book by Professor O. Svelto. The collection of problems presented in this book appears therefore a natural complement to Svelto's textbook for testing and developing the skills acquired in the reading of the theory; however, it may also be a useful support to any general textbook on laser physics, wherein problems are usually not solved in detail. We remark that this is, to our knowledge, the first book to provide a complete and satisfactory set of solved problems in such a highly developing field of science and technology. The problems fall mainly into three distinct categories: (i) numerical/applied problems, which help the reader to become confident and familiar with the basic concepts and methods of laser physics, and to acquire a feeling for numerical parameters entering in real-world laser systems; (ii) complementary problems, that present in detail demonstrations of some analytical parts not given in the textbook; and (iii) advanced problems, aimed either to provide a deeper understanding of the subject or to cover more recent developments in the field. Audience: This book is primarily intended for undergraduate and graduate students in physics, engineering, and chemistry. However, it may also be a useful tool for industrial professionals working in the field of laser technologies and laser applications, as well as for researchers interested in basic aspects of real-world lasers andrelated fields.

In recent decades, there has been a phenomenal growth in the field of photonic crystal research and has emerged as an interdisciplinary area. Photonic crystals are usually nanostructured electromagnetic media consisting of periodic variation of dielectric constant, which prohibit certain electromagnetic wave frequency ranges called photonic bandgaps to propagate through them. Photonic crystals elicited numerous interesting features by unprecedented control of light and their exploitation is a promising tool in nanophotonics and designing optical components. The book 'Advances in Photonic Crystals and Devices' is designed with 15 chapters with introductory as well as research and application based contents. It covers the following highlighted features: Basics of photonic crystals and photonic crystal fibers Different theoretical as well as experimental approaches Current research advances from around the globe Nonlinear optics and super-continuum generation in photonic crystal fibers Magnetized cold plasma photonic crystals Liquid crystal defect embedded with graphene layers Biophysics and biomedical applications as optical sensors Two-dimensional photonic crystal demultiplexer Optical logic gates using photonic crystals A large number of references The goal of this book is to draw the background in understanding, fabrication and characterization of photonic crystals using a variety of materials and their applications in design of several optical devices. Though the book is useful as a reference for the researchers working in the area of photonics, optical computing and fabrication of nanophotonic devices, it is intended for the beginners like students pursuing their masters' degree in photonics.

This book covers the entire field of tunable lasers, with the exception of dye lasers. Following an introductory chapter on common general principles, the remaining chapters - all written by leading experts in the field - each treat a particular class of tunable laser or process. In each case, a theoretical treatment is combined with a detailed practical description of the lasers and their operation. The book is written so as to be readily accessible to researchers and students alike. It is especially intended to enable the non-expert to choose the most appropriate tunable laser for a specific application. In this second edition an added chapter with extensive references to recent literature reviews the advances that haveoccured since the publication of the original edition.

Enhancement cavities are passive optical resonators in which continuous-wave laser radiation or pulses of a frequency comb are coherently overlapped, allowing for a power and intensity scaling of up to several orders of magnitude. A prominent application is the table-top generation of bright, laser-like radiation in spectral regions where direct laser action is inefficient or not available at all, via intracavity nonlinear optical processes. However, to exploit the full capacity of this technique further progress is needed. This thesis covers central problems of enhancement cavities, such as finding limitations in scaling the circulating power, measuring cavity parameters with high accuracy, tailoring transverse modes and coupling out radiation generated in the cavity. Unprecedented intracavity laser powers were demonstrated, surpassing previous results by an order of magnitude. As an application, harmonics of the fundamental 1040-nm radiation up to the 21st order are generated. Besides reporting these fine experimental results, the thesis provides an excellent introduction into the physics of enhancement cavities, supported by more than 140 references.

The third edition of Dye Lasers has been prepared in response to demand for an updated version of this well-known Topics volume. The classic chapters on continuous-wave dye lasers and properties of dye lasers are unchanged, but are now complemented by an additional chapter on continuous-wave dye lasers that takes account of recent advances. The chapters on principles of operation and mode-locking of dye lasers have been updated. Finally, the chapter on applications, which was originally written when a synopsis was still possible, has been eliminated completely in this edition, since nowadays dye lasers have penetrated almost all fields of science and technology and applications have become innumerable. In its place there is a new chapter on wavemeters. This book provides an excellent introduction to dye lasers and contains much useful information for scientists and engineers who deal with their applications.

It was a greatest pleasure for me to learn that Springer-Verlag wished to produce a second edition of my book. In this connection, Dr. H. Lotsch asked me to send hirn a list of misprints, mistakes, and inaccuracies that had been noticed in the first edition and to make corresponding corrections without disturbing the layout or the typo graphy too much. I accepted this opportunity with alacrity and, moreover, found some free places in the text where I was able to insert some concise, up-to-date information about new lasing compounds and stimulated emission channels. It was also possible to increase the number of reference citations. The reader of the second edition hence has access to more complete data on insulating laser crystals. However, sections on laser-crystal physics have not been updated, because a satisfactory de scription of the progress made in the last ten years in this field would have required the sections to be extended enormously or even a new book to be written. Moscow, July 1989 ALEXANDER A. KAMINSKII Preface to the First Edition The greatest reward for an author is the feeling of satisfaction he gets when it becomes c1ear to hirn that readers find his work useful. After my book appeared in the USSR in 1975 I received many letters from fellow physicists inc1uding colleagues from Western European countries and the USA."

This book is devoted to the investigations of non-stationary electromagnetic processes. The investigations are undertaken analytically mainly using the Volterra integral equations approach. The book contains a systematic statement of this approach for the investigations of electrodynamics phenomena in the time domain and new results and applications in microwave techniques and photonics. Particular consideration is given to electromagnetic transients in time-varying media and their potential applications. The approach is formulated and electromagnetic phenomena are investigated in detail for a hollow metal waveguide, which contains moving dielectric or plasma-bounded medium, and dielectric waveguides with time-varying medium inside a core.

The book provides a unique overview on laser techniques and applications for the purpose of improving adhesion by altering surface chemistry and topography/morphology of the substrate. It details laser surface modification techniques for a wide range of industrially relevant materials (plastics, metals, ceramics, composites) with the aim to improve and enhance their adhesion to other materials. The joining of different materials is of critical importance in the fabrication of many and varied products.

This book contains a selection of papers and articles in instrumentation previously pub lished in technical periodicals and journals of learned societies. Our selection has been made to illustrate aspects of current practice and applications of instrumentation. The book does not attempt to be encyclopaedic in its coverage of the subject, but to provide some examples of general transduction techniques, of the sensing of particular measurands, of components of instrumentation systems and of instrumentation practice in two very different environments, the food industry and the nuclear power industry. We have made the selection particularly to provide papers appropriate to the study of the Open University course T292 Instrumentation. The papers have been chosen so that the book covers a wide spectrum of instrumentation techniques. Because of this, the book should be of value not only to students of instrumen tation, but also to practising engineers and scientists wishing to glean ideas from areas of instrumentation outside their own fields of expertise. In recent years instrumentation has emerged as a discipline in its own right rather than as an adjunct to traditional science and engineering disciplines. This development has been driven partly by the needs of industries for new and improved sensing techniques, and partly by new technological developments such as microprocessors, optical fibres and in tegrated silicon sensors which are revolutionising sensing and signal processing practice."
