Foreword by Charles H Townes This volume includes highlights of the theories underlying the essential phenomena occurring in novel semiconductor lasers as well as the principles of operation of selected heterostructure lasers. To understand scattering processes in heterostructure lasers and related optoelectronic devices, it is essential to consider the role of dimensional confinement of charge carriers as well as acoustical and optical phonons in quantum structures. Indeed, it is important to consider the confinement of both phonons and carriers in the design and modeling of novel semiconductor lasers such as the tunnel injection laser, quantum well intersubband lasers, and quantum dot lasers. The full exploitation of dimensional confinement leads to the exciting new capability of scattering time engineering in novel semiconductor lasers.As a result of continuing advances in techniques for growing quantum heterostructures, recent developments are likely to be followed in coming years by many more advances in semiconductor lasers and optoelectronics. As our understanding of these devices and the ability to fabricate them grow, so does our need for more sophisticated theories and simulation methods bridging the gap between quantum and classical transport.

With the maturation of laser technology in diagnostic and conservation applications, conservation scientists, archeologists, art historians, researchers, and advanced science-oriented students now have the tools necessary for preserving the future of our past-our cultural heritage. Presenting recent developments in the field, Lasers in the Preservation of Cultural Heritage: Principles and Applications addresses the basic concepts of laser applications and supplies case studies of analytical, structural diagnostic, and laser cleaning applications. The book provides a comprehensive presentation of the fundamental principles and applications of modern laser technology in the analysis of composition, diagnostics of structural integrity, and conservation of artworks and antiquities. Beginning with an introduction to the basic techniques used in art conservation and archeology, the book describes the fundamental aspects of laser-matter interactions, emphasizing laser diagnostics and laser processing applications. The next few chapters focus on laser-based spectroscopic techniques for the analysis of the composition of materials in art and archaeology, including laser-induced breakdown, Raman, and laser-induced fluorescence spectroscopic techniques. The book proceeds to highlight nondestructive diagnostic techniques, laser processing applications, laser applications for the cleaning of paintings and stone, and methods for the removal of encrustations. It concludes with case studies for the conservation of materials like parchment, paper, metal, ivory, and wood, and includes conservation approaches for modern paintings. Bridging science with art, Lasers in the Preservation of Cultural Heritage presents a systematic overview of the fundamentals and applications of laser techniques in artwork conservation and archeological science.

Diode lasers use nearly microscopic chips of gallium-arsenide or other exotic semiconductor material to generate coherent light in a very small package. Their compact size, reliability, and low cost means that they find applications in all aspects of modern technology-most importantly they drive modern optical telecommunication systems. Diode Lasers presents a comprehensive introduction to the principles and operation of diode lasers. It begins with a review of semiconductor physics and laser fundamentals, before describing the most basic homojunction laser. Later chapters describe more advanced laser types and their applications, and the book concludes with chapters describing the most recently developed and exotic laser designs. The author's intuitive style, coupled with an extensive set of worked examples and sample problems, make this the ideal introduction for undergraduate and graduate level students.

Covering a broad range of topics in modern optical physics and engineering, this textbook is invaluable for undergraduate students studying laser physics, optoelectronics, photonics, applied optics and optical engineering. This new edition has been re-organized, and now covers many new topics such as the optics of stratified media, quantum well lasers and modulators, free electron lasers, diode-pumped solid state and gas lasers, imaging and non-imaging optical systems, squeezed light, periodic poling in nonlinear media, very short pulse lasers and new applications of lasers. The textbook gives a detailed introduction to the basic physics and engineering of lasers, as well as covering the design and operational principles of a wide range of optical systems and electro-optic devices. It features full details of important derivations and results, and provides many practical examples of the design, construction and performance characteristics of different types of lasers and electro-optic devices.

This thesis focuses on two areas - the development of miniature plastic lasers that can be powered by LEDs, and the application of these lasers as highly sensitive sensors for vapours of nitroaromatic explosives (e.g. TNT). Polymer lasers are extremely compact visible lasers; the research described in the thesis is groundbreaking, driving forward the technology and physical understanding to allow these lasers to be routinely pumped by a single high-power LED. A notable advance in the work is the demonstration of nanoimprinted polymer lasers, which exhibit the world's lowest pump threshold densities by two orders of magnitude. The thesis also advances the application of these compact, novel lasers as highly sensitive detectors of explosive vapours, demonstrating that rapid detection can be achieved when microporous polymers are used. This work also demonstrates a prototype CMOS-based microsystem sensor for explosive vapours, exploiting a new detection approach.

This book is based on a course given by the author to third and fourth year undergraduate students from physics, engineering physics and electrical engineering. The purpose is to introduce and explain some of the fundamental principles underlying laser beam control in optoelectronics, especially those in relation to optical anisotropy which is at the heart of many optical devices. The contents of the book are scattered in many sources and there seems to be no single source available at the undergraduate level. That is why the present book is written. The book attempts to give the reader a good background needed for working in a laser, optoelectronic or photonic laboratory so that the use of equipment and the control of laser beams can be mastered without difficulty.

Laser diodes represent a key element in the emerging field of opto electronics which includes, for example, optical communication, optical sensors or optical disc systems. For all these applications, information is either transmitted, stored or read out. The performance of these systems depends to a great deal on the performance of the laser diode with regard to its modulation and noise characteristics. Since the modulation and noise characteristics of laser diodes are of vital importance for optoelectronic systems, the need for a book arises that concentrates on this subject. This book thus closes the gap between books on the device physics of semiconductor lasers and books on system design. Complementary to the specific topics concerning modulation and noise, the first part of this book reviews the basic laser characteristics, so that even a reader without detailed knowledge of laser diodes may follow the text. In order to understand the book, the reader should have a basic knowledge of electronics, semiconductor physics and optical communica tions. The work is primarily written for the engineer or scientist working in the field of optoelectronics; however, since the book is self-contained and since it contains a lot of numerical examples, it may serve as a textbook for graduate students. In the field of laser diode modulation and noise a vast amount has been published during recent years. Even though the book contains more than 600 references, only a small part of the existing literature is included.
