Fluoride Glasses And Methods For Making Optical Fibers From

Fluoride Glass Fiber Optics reviews the fundamental aspects of fluoride glasses. This book is divided into nine chapters. Chapter 1 discusses the wide range of fluoride glasses with an emphasis on fluorozirconate-based compositions. The structure of simple fluoride systems, such as BaF2 binary glass is elaborated in Chapter 2. The third chapter covers the intrinsic transparency of fluoride glasses from the UV to the IR, with particular emphasis on the multiphonon edge and electronic edge. The next three chapters are devoted to ultra-low loss optical fibers, reviewing methods for purifying and analyzing the fluoride glass raw materials. The sources of loss are considered in Chapter 6, while the work performed on the durability of fluoride glasses is analyzed in Chapter 7. Chapter 8 focuses on the effects of radiation on fluoride glasses. The last chapter deliberates the area of active phenomena such as doping of fluoride glasses with rare-earth elements for fluorescence and lasing, as well as frequency doubling. This publication is a good reference for students and researchers conducting work on fluoride glasses.

One of the most exciting prospects for optical fibres made from fluoride glasses is the possibility of providing long distance optical communication systems without the need for repeaters. This objective has stimulated much of the work into fluoride glasses over the past ten years, and has prompted the writing of this book. It has also emerged that fluoride fibres can transmit both visible and infrared energy (from about 0.5 to 5 ,urn) and that they have many applications outside the field of telecommunications. These include optical fibre sensors (particularly in remote infrared spectroscopy), laser surgery and fibre lasers. Several companies are now established in the field, and good quality fluoride fibres are available from sources throughout the USA, Europe and Japan. Moreover, the first commercial instruments based on fluoride fibres are finding their way to the market place and these fibres will undoubtedly form the basis of many more instruments yet to be developed. The work presented in this book represents the field both from an academic understanding of the materials and ways to convert them into fibre, and from a practical and commercial viewpoint. The principal author and some of the co authors are based at the British Telecom Research Laboratories in the UK.

This book gives an overview on mid-infrared optical glass and fibers laser, it cover the underlying principle, historic background, as well as recent advances in materials processing and enhanced properties for rare earth doped luminescence, spectroscopy lasers, or optical nonlinearity applications. It describes in great detail, the preparation of high purity non-oxide IR glass and fibers to be used as mid-IR fiber laser and supercontinuum sources for optical fiber spectroscopy. It will be useful for academics, researchers and engineers in various disciplines who require a broad introduction to the subject and would like to learn more about the state-of-the-art and upcoming trends in mid-infrared fiber source development, particularly for industrial, medical and military applications.
