Further the book includes extensive coverage of optoelectronic devices, fibre optic communication and fibre optic sensors. The book includes many solved problems throughout the text to support the theoretical concepts and help in understanding of underlying principles. Review questions have been included at the end of each chapter to practise and self-study. Spread in Ten Chapters the book broadly covers: " Characteristics of lasers, mode locking, Q-switching, powerful lasers, frequency stabilisation " Overview of applications of lasers in science, engineering and medicine; reliability and safety aspects " Laser interferometer, laser strain gauges, laser Doppler velocimeter, laser ranging, mechanical cutting, welding, scribing, holography " Applications of Raman spectroscopy " Application of laser devices, optical fibers etc., in fiber optic communications " Integrated optics, radiation source, transmission link, detector " Fibre optical sensors, non-intrusively, displacements, pressure, temperature, high currents, angular velocity " Future perspectives nanophotonics, quantum dots, photonic crystals

The complete, practical sourcebook for laser sensing and measurement This is a systematic, up-to-date guide to laser instrumentation for sensing and measurement in contemporary scientific, industrial, automotive and avionics applications. Dr. Silvano Donati presents clear design rules and useful hints for practical implementation of a wide variety of laser instruments. For each type of instrument, the author outlines basic principles, physical limitations, reasonable performance expectations, optical design issues, and electronic signal handling--illustrated with block schemes. Coverage includes: Interferometers for sub-micrometer displacement measurements Nanometer vibrometers and structural integrity testing Doppler velocimeters for anemometry of fluids Range finders and anti-collision systems Non-contact wire-diameter and particle-diameter sizing Alignment and level meter apparatuses Ring laser and optical fiber gyroscopes Optical fiber sensors Thorough and accessible, Electro-Optical Instrumentation offers balanced coverage of both optical and electronic issues and challenges. It will give working electronic engineers and scientists the knowledge they need to design virtually any electro-optical instrumentation system.

In this newest edition of Optics and Lasers, I have added a substantial number of problems and moved most of the older ones to the end of the book. There are now about one hundred problems, which, I hope, will make the book more useful in the classroom. As before, some of the problems derive an espe cially important or useful result; these I have left integrated within the body of the book. In such cases, I state the result and, often, give it an equation number and a citation in the index. Teachers who adopt the book may obtain solutions to the problems by asking me for them on letterhead stationery. In addition, I have rewritten over a dozen paragraphs to improve their clarity or precision and, further , corrected minor errors of punctuation and taken care of other such small details. The field of optics has been changing greatly for almost two dozen years. Partly because of the applied or engineering nature of much of modern optics, there has been a need for a practical text that surveys the entire field. Such a book should not be a classical-optics text, but, rather , it should be strong on principles, applications and instrumentation, on lasers, holography and coherent light, and on optical-fiber waveguides. On the other hand, it should concern itself relatively little with such admittedly interesting phenomena as the formation of the rainbow or the precise determination of the speed of light.

A textbook on lasers and optical engineering should include all aspects of lasers and optics; however, this is a large undertaking. The objective of this book is to give an introduction to the subject on a level such that under graduate students (mostly juniors/seniors), from disciplines like electrical engineering, physics, and optical engineering, can use the book. To achieve this goal, a lot of basic background material, central to the subject, has been covered in optics and laser physics. Students with an elementary knowledge of freshman physics and with no formal courses in electromagnetic theory should be able to follow the book, although for some sections, knowledge of electromagnetic theory, the Fourier transform, and linear systems would be highly beneficial. There are excellent books on optics, laser physics, and optical engineering. Actually, most of my knowledge was acquired through these. However, when I started teaching an undergraduate course in 1974, under the same heading as the title of this book, I had to use four books to cover the material I thought an electrical engineer needed for his introduction to the world of lasers and optical engineering. In my sabbatical year, 1980-1981, I started writing class notes for my students, so that they could get through the course by possibly buying only one book. Eventually, these notes grew with the help of my undergraduate and graduate students, and the final result is this book.

This third edition of the biomedical optics classic Tissue Optics covers the continued intensive growth in tissue optics—in particular, the field of tissue diagnostics and imaging—that has occurred since 2007. As in the first two editions, Part I describes fundamentals and basic research, and Part II presents instrumentation and medical applications. However, for the reader’s convenience, this third edition has been reorganized into 14 chapters instead of 9. The chapters covering optical coherence tomography, digital holography and interferometry, controlling optical properties of tissues, nonlinear spectroscopy, and imaging have all been substantially updated. The book is intended for researchers, teachers, and graduate and undergraduate students specializing in the physics of living systems, biomedical optics and biophotonics, laser biophysics, and applications of lasers in biomedicine. It can also be used as a textbook for courses in medical physics, medical engineering, and medical biology.

Broadly tunable lasers have had, and continue to have, an enormous impact in many and diverse fields of science and technology. From a renaissance in spectroscopy to laser guide stars and laser cooling, the nexus is the tunable laser. Tunable Laser Optics offers a transparent and comprehensive treatment of the physics of tunable laser optics based on a detailed description of first principles. Authored by a leading expert in the field, the book covers the optics and optical principles needed to build lasers, the optics instrumentation necessary to characterize laser emission, and laser-based optical instrumentation, addressing key topics such as Dirac’s notation, the interferometric equation, the uncertainty principle, pulse compression, and tunable narrow-linewidth lasers. This revised, expanded, and improved Second Edition: Contains new and additional material on tunable lasers and quantum optics Explains the first principles of tunable laser optics in a clear and concise manner Presents an explicit exposition of the relevant theory, without the use of short cuts Employs numerous examples, case studies, and figures to illustrate important concepts Includes carefully designed problems of direct practical significance to stimulate application Emphasizing the utilitarian aspects of the optics and theory, Tunable Laser Optics, Second Edition provides valuable insight into the optics and the trade-offs involved in the design and construction of tunable lasers and optical devices. It makes an ideal textbook for advanced undergraduate-level and graduate-level optics courses for physics and engineering students, as well as a handy reference for researchers and experimentalists.
