This book treats the interaction of radiation with matter, particular attention being paid to the laser. Knowledge is assumed of the usual half-year introduction of quantum mechanics found in undergraduate physics curricula. The material can be covered in two semesters, or, alternatively, the first part (Chaps 1-13) can be used as a one-semester course in which quantum mechanical aspects of the electromagnetic field are ignored. Each chapter is accompanied by problems that illustrate the text and give useful (occasionally new) results. Existing laser media are intrinsically quantum mechanical and are most easily studied with the quantum theory. Understanding the laser along these lines enlivens one's understanding of quantum mechanics itself. In fact, the material constitutes a viable, applied alternative for the usual second and third semesters of quantum mechanics.

Lasers with a gaseous active medium offer high flexibility, wide tunability, and advantages in cost, beam quality, and power scalability. Gas lasers have tended to become overshadowed by the recent popularity and proliferation of semiconductor lasers. As a result of this shift in focus, details on modern developments in gas lasers are difficult to find. In addition, different types of gas lasers have unique properties that are not well-described in other references. Collecting expert contributions from authorities dealing with specific types of lasers, Gas Lasers examines the fundamentals, current research, and applications of this important class of laser. It is important to understand all types of lasers, from solid-state to gaseous, before making a decision for any application. This book fills in the gaps by discussing the definition and properties of gaseous media along with its fluid dynamics, electric excitation circuits, and optical resonators. From this foundation, the discussion launches into the basic physics, characteristics, applications, and current research efforts for specific types of gas lasers: CO lasers, CO2 lasers, HF/DF lasers, excimer lasers, iodine lasers, and metal vapor lasers. The final chapter discusses miscellaneous lasers not covered in the previous chapters. Collecting hard-to-find material into a single, convenient source, Gas Lasers offers an encyclopedic survey that helps you approach new applications with a more complete inventory of laser options.

Nanotechnology is the art, science, and engineering of designing materials, devices, and systems at the nanoscale from bottom-up and/or top-down approaches. The material properties at the nanoscale are governed by quantum mechanics, and hence are drastically different than those at the macro/micro scale. It is thus no surprise, that nanotechnology has led to a scientific and technological revolution. This book provides a gentle introduction to the field of nanotechnology for first-year undergraduate students. It not only covers the fundamental scientific concepts in a tutorial fashion, but also provides an overview of applications in nanoelectronics, spintronics, nanophotonics, nanofabrication and nanocharacterization. End of chapter research assignments focus on nanomanufacturing, computing and communication, renewable energy, defense applications, food processing and agriculture, automobile and aerospace technology, nanobiotechnology and bionanotechnology, industrial and consumer applications. Finally, the topics related to safety, health, and societal impact of nanotechnology are discussed.

Over the past decade, plasmonic nanoparticles have been the subject of extensive research, owing to their remarkable optical properties. These properties arise from a collective oscillation of the conductive electrons at the nanoparticle surface under light irradiation, known as localized surface plasmon (LSP). LSP is characterized by (i) a strong absorption and scattering of the light depending on the geometrical parameters of the nanoparticles and (ii) a strong amplification of the local field in the vicinity of the nanoparticles. Quite recently, it was shown that the activation and the initiation of chemical reactions or physical processes can be facilitated using LSP excitation. Such exploitation presents two main advantages: an enhanced yield and a fine control of chemical reactions at the nanoscale. These topics have become very active and are in line with molecular plasmonics. This book explores this new field and provides a broad view on the exploitation of plasmonics in chemical and biological fields.

This book describes in detail the main concepts of theoretical spectroscopy of transition metal and rare-earth ions. It shows how the energy levels of different electron configurations are formed and calculated for the ions in a free state and in crystals, how group theory can help in solving main spectroscopic problems, and how the modern DFT-based methods of calculations of electronic structure can be combined with the semi-empirical crystal field models. The style of presentation makes the book helpful for a wide audience ranging from graduate students to experienced researchers. Performance of optical materials crucially depends on the impurity ions intentionally introduced into the crystalline host materials. The color of these materials, their emission and absorption spectra can be understood by analyzing the relations between the electronic properties of impurity ions and host crystal structure, which constitutes the main content of this book. It describes in detail the main concepts of theoretical spectroscopy of transition metal and rare earth ions.

"This book provides a practical description of optics that satisfies the needs often encountered by some engineers in the practice of their profession. Optical components, including optical sources and detectors, have found their way into products that we buy for the house, and into industrial equipment. As a textbook, it provides an efficient tool for the student to gain in-depth knowledge of a subject, with homework problems to test and verify mastery of the subject." -Antonio Sanchez-Rubio, MIT Lincoln Laboratory, Lexington, Massachusetts, USA "This book covers all the experimental tools, described meticulously and with clear illustrations, which students will need to perform their experiments. I wish I had this book when I taught an optics course!" -A.K. Ramdas, Purdue University, West Lafayette, Indiana, USA This book provides readers with a brief introduction to optical components. Materials presented in this book prepare readers to deal with optical components in the areas of optics and optical technology. Introduction to Optical Components features nine chapters with topics ranging from lenses (materials, magnifiers, and cameras); mirrors (spherical, ellipsoidal, and aberrations); diffraction gratings (holographic and multilayer dielectric); polarizers (birefringent, reflective, and Jones matrix algebra); windows (UV and AR coating materials); filters (neutral density and Raman); beamsplitters (plate, cube, and pellicle); sources (light-emitting diodes and lasers); and detectors (thermal, photon, and photodetector noise). This text also features a detailed discussion of non-ideal effects for practical components using minimal amounts of derivations (that do not compromise essential physical, mathematical, or material properties). While there are numerous books that feature "optical" in their title, to date, no textbook on optical components exists. It is for this reason that Introduction to Optical Components is such a vital resource. The technical level of this book is equivalent to an undergraduate course in the optics and optical technology curriculum. Students are required to have little familiarity with optics. Practitioners in optics and optical technology will also find this book useful. Each chapter includes numerous mathematical equations; tables providing useful optical parameters for many optical materials; and end-of-chapter questions and their corresponding solutions.

This book is a must-have reference for professionals in developing hyperspectral satellites and data applications. It is also an excellent introductory book for early practitioners and students who want to learn more about hyperspectral satellites and their applications.

The semiconductor laser, invented over 50 years ago, has had an enormous impact on the digital technologies that now dominate so many applications in business, commerce and the home. The laser is used in all types of optical fibre communication networks that enable the operation of the internet, e-mail, voice and skype transmission. Approximately one billion are produced each year for a market valued at around $5 billion. Nearly all semiconductor lasers now use extremely thin layers of light emitting materials (quantum well lasers). Increasingly smaller nanostructures are used in the form of quantum dots. The impact of the semiconductor laser is surprising in the light of the complexity of the physical processes that determine the operation of every device. This text takes the reader from the fundamental optical gain and carrier recombination processes in quantum wells and quantum dots, through descriptions of common device structures to an understanding of their operating characteristics. It has a consistent treatment of both quantum dot and quantum well structures taking full account of their dimensionality, which provides the reader with a complete account of contemporary quantum confined laser diodes. It includes plenty of illustrations from both model calculations and experimental observations. There are numerous exercises, many designed to give a feel for values of key parameters and experience obtaining quantitative results from equations. Some challenging concepts, previously the subject matter of research monographs, are treated here at this level for the first time.
