Theoretical Spectroscopy of Transition Metal and Rare Earth Ions - From Free State to Crystal Field (Hardcover): Mikhail G.... Theoretical Spectroscopy of Transition Metal and Rare Earth Ions - From Free State to Crystal Field (Hardcover)
Mikhail G. Brik, Ma Chong-Geng
R2,986 Discovery Miles 29 860 Ships in 12 - 17 working days

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 1996 volume provided the first comprehensive overview of the use of ultraviolet laser radiation in the processing of materials. Lasers operating at ultraviolet wavelengths combine the ability to vaporise the most refractory of materials with the precision to ablate micron-sized holes in polymers and remove thin layers from the cornea for corrective surgery of the human eye. This book explores the use of UV laser radiation for the ablation and deposition of metals, insulating solids, polymers, semiconductors and superconductors. Emphasis has been placed on understanding the physical mechanisms accompanying these processes and the conversion of intense UV radiation to photothermal and photochemical energy in irradiated materials. This will be an invaluable source-book of current information in the rapidly developing field of laser applications for engineers, scientists, researchers and students in universities, government laboratories and the private sector, and will also form a valuable supplementary text for graduate courses in materials science.

Quantum Confined Laser Devices - Optical gain and recombination in semiconductors (Paperback): Peter Blood Quantum Confined Laser Devices - Optical gain and recombination in semiconductors (Paperback)
Peter Blood
R902 Discovery Miles 9 020 Ships in 12 - 17 working days

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.

Psang Dain Lin
R4,299 Discovery Miles 42 990 Ships in 12 - 17 working days

This book computes the first- and second-order derivative matrices of skew ray and optical path length, while also providing an important mathematical tool for automatic optical design. This book consists of three parts. Part One reviews the basic theories of skew-ray tracing, paraxial optics and primary aberrations - essential reading that lays the foundation for the modeling work presented in the rest of this book. Part Two derives the Jacobian matrices of a ray and its optical path length. Although this issue is also addressed in other publications, they generally fail to consider all of the variables of a non-axially symmetrical system. The modeling work thus provides a more robust framework for the analysis and design of non-axially symmetrical systems such as prisms and head-up displays. Lastly, Part Three proposes a computational scheme for deriving the Hessian matrices of a ray and its optical path length, offering an effective means of determining an appropriate search direction when tuning the system variables in the system design process.

R2,973 Discovery Miles 29 730 Ships in 12 - 17 working days

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 lies at the interface of machine learning - a subfield of computer science that develops algorithms for challenging tasks such as shape or image recognition, where traditional algorithms fail - and photonics - the physical science of light, which underlies many of the optical communications technologies used in our information society. It provides a thorough introduction to reservoir computing and field-programmable gate arrays (FPGAs). Recently, photonic implementations of reservoir computing (a machine learning algorithm based on artificial neural networks) have made a breakthrough in optical computing possible. In this book, the author pushes the performance of these systems significantly beyond what was achieved before. By interfacing a photonic reservoir computer with a high-speed electronic device (an FPGA), the author successfully interacts with the reservoir computer in real time, allowing him to considerably expand its capabilities and range of possible applications. Furthermore, the author draws on his expertise in machine learning and FPGA programming to make progress on a very different problem, namely the real-time image analysis of optical coherence tomography for atherosclerotic arteries.
