Book Description
The use oflasers has entered almost every facet of medicine and biology. Therefore, it is to be expected that the reviews contained in this vol urne will reflect this diversity. As dinical acceptance has grown with various diagnostic and therapeutic applications, so has the need for a more thorough understanding of the theoretical background for each. This is especially true where a correlation is to be made between the theoretical background and the experimental data. It is only in this way that we can attain the optimal form of any therapy. The basic coupling ofenergy into biological tissue and its conversion into heat is characterized by many parameters. One ofthe most important is pulse duration. The review by Bimgruber in Chapter 6 shows how our knowledge ofthis parameter has been extended.The need for a more basic understanding of the interaction of electromagnetic energy with various kinds of materials has led to investigations on the nature of plasmas their stability and instability,and how theyexist. Docchio reviews the factors that cause them to occur at a specific locale and then to move away from that site. The availabilityofmany types ofoptical fibers has extended our ability to deliver laser energy from various types oflasers into almost anyselected location. This is particularly useful in medicine, where less invasive ap proaches to surgery and diagnosis are always helpful. However, as Rol and his colleagues explain, the power-handling capabilities ofoptical fibers limit many applications, particularly for short-duration, high-peak-power laser pulses.

Book Description
Much of the material in this book represents a departure from that presented earlier in the series. Volumes 1 and 2 presented almost exclusively reviews by American authors of American work. As science is international, it is rare that in two different parts of the world large groups of researchers in the same field remain relatively uninformed about each other's work. However, during the time since the initiation of this series, a large body of research has grown up in Russia that is almost unknown outside, as the original reports are largely untranslated. For this reason, an extensive review is presented here of the entire field of Russian applications of lasers in medicine and biology. Although the author, Dr. Gamaleya, has not worked directly with many of the applications, he has a general background in laser usage and has received much help from his colleagues in assembling the material. His review is restricted to Russian research. This does not mean that he is unaware of Western advances, rather that he has restricted his material to the parts that are peculiarly Russian or are significant confir mations of earlier work. Some of the Russian developments are quite novel and will certainly suggest to the careful reader new interpretations of old data, and possibly even new lines of research. The mechanisms proposed for the interaction of the high-intensity monochromatic light from lasers with biological material continue to grow in complexity.

Book Description
The diversity of the chapters presented in this volume illustrates not only the many applications of lasers, but also the fact that, in many cases, these are not new uses of lasers, but rather improvements of laser techniques already widely accepted in both research and clinical situations. Biological reactions to some special aspects of laser exposure continue to show new effects, which have implications for the ever-present topic of laser safety. Such biological reactions are included in fields of research which depend on properties of electromagnetic radiation exposure only possible with lasers, for example, the short pulses necessary for the temperature-jump experiments reviewed by Reiss: Speciality lasers, such as the transverse excitation atmospheric (TEA) or excimer lasers, add new wavelengths and pulse domains to those already available for biological application. A description of these new types of lasers by Osgood is included to indicate new possibilities for future use and to avoid limiting our coverage to well-developed present-day applications. Hillenkamp and Kaufmann describe a microprobe mass spectrograph for analysis of the minute amounts of material evaporated by a laser pulse. The analytical possibilities of this instrument are far-reaching, and some of the various results are described to illustrate the power of their method, as well as to show the types of problems that are suitable for it. The initial steps in photosynthesis have become the subject of intensive investigation.

Book Description
In the intervening years since the publication of Volume I, the develop ment of new uses for the various types of lasers has proceeded at a rate more rapid than even the most fanciful dreamers envisioned. Of course, the main effort has been on the laser itself-new wavelengths, shorter and longer time domains for pulses, increases in power, and, most important, greater reliability. In its first stage the laser was described as a solution in search of a problem. The production of holograms was one problem whose solution seemed to involve large number of lasers. However that proposal had its own difficulties, for the hologram itself was described as a solution searching for a problem. But all of that now is a chapter from ancient history . On the current scene the laser is used in industrial pro duction lines, as a classroom item at all levels of education, and in com mercial usage such that the public is generally exposed to the laser devices themselves. Trial runs have been made, e. g. , of laser-based supermarket checkout devices and as commercial exploitation of this item begins, cer tainly many more similar adaptations will follow. However, the shift in emphasis from research usage of lasers to de velopment and production has been relative rather than absolute. The use of the laser in research has not lessened; rather it has grown at as fast a pace. Yet a similar trend is seen there also.

Book Description
The increasing use of fiber optics in the field of medicine has created a need for an interdisciplinary perspective of the technology and methods for physicians as well as engineers and biophysicists. This book presents a comprehensive examination of lasers and optical fibers in an hierarchical, three-tier system. Each chapter is divided into three basic sections: the Fundamentals section provides an overview of basic concepts and background; the Principles section offers an in-depth engineering approach; and the Advances section features specific information on systems and biophysical parameters. All those interested in the fields of lasers and fiber optics will find this book fascinating and instructive reading.

Book Description
The laser's range of application is extraordinary. Arthur Schawlow says, "What instrument can shuck a bucket of oysters, correct typing errors, fuse atoms, lay a straight line for a garden bed, repair detached retinas, and drill holes in dia monds?"O The laser's specifically biomedical uses cover a similarly broad and interesting spectrum. In this book, I have endeavored to convey some of the fas cination that the laser has long held for me. It is my hope that both clinicians and researchers in the various medical and surgical specialties will find the book a use ful introduction. Biologists, particularly molecular biologists, should also find a great deal of relevant information herein. This volume's distinguished contributors provide admirably lucid discussions of laser principles, instrumentation, and current practice in their respective special ties. Safety, design, capabilities, and costs of various lasers are also reviewed. We have aimed to create a practical text that is comprehensive but not exhaustive. Our emphasis on the practical, rather than the esoteric, is dictated not only by the short history of biomedical laser use, but by the extent of the community to which this information will appeal.
