This monograph is devoted to the description of the physical fundamentals of laser refractography—a novel informational-measuring technique for the diagnostics of optically inhomogeneous media and flows, based on the idea of using spatially structured probe laser radiation in combination with its digital recording and c- puter techniques for the differential processing of refraction patterns. Considered are the physical fundamentals of this technique, actual optical schemes, methods of processing refraction patterns, and possible applications. This informational technique can be employed in such areas of science and technology as require remote nonperturbative monitoring of optical, thermophysical, chemical, aerohydrodynamic, and manufacturing processes. The monograph can also be recommended for students and postgraduates of - formational, laser, electro-optical, thermophysical, chemical, and other specialties. Laser refractography is a conceptually novel refraction method for the diagn- tics of inhomogeneous media, based on the idea of using spatially structured probe laser radiation in combination with its digital recording and computer techniques for the differential processing of refraction patterns.

This book considers some general laser-induced processes that are involved in laser-matter interactions. A brief review is presented about a very interesting application of laser beams in the fields of materials science: the growth of zinc oxide (ZnO) nanostructured films by Pulsed Laser Deposition (PLD). In addition, safe and precise cavity detection, especially of dangerous or inaccessible voids, is essential to safe production in a working mine. The advantages and disadvantages of laser detection systems are analysed, and a combination of laser scanning techniques and conventional survey methodology is proposed. Other chapters in this book present an overview on laser cladding, a discussion of the applications of structured laser beams in laser refractography technology, a review of some fundamentals of laser-induced breakdown spectroscopy (LIBS) and an analysis of laser forming of steel parts by means of diode lasers.

A femtosecond laser is a laser which emits ultrashort pulses, used for minimally invasive corneal surgery. This book is a concise guide to femtosecond laser technology and the various techniques for its use. The internationally recognised authors from the US, Europe and Asia, begin with an introduction and description of current technology and future prospects. The following chapters discuss the step by step application of the techniques to different ocular disorders. The book includes more than 200 colour illustrations and images and an ancillary DVD presents real life examples of various femtosecond laser procedures.

American ophthalmologists, who have only recently been given FDA approval to perform Photorefractive Keratectomy for low myopia, will find this resource especially valuable. The contributors are primarily British and Australian researchers and clinicians who have been working to develop this instrument and refine its clinical applications. Scientific principles and current clinical and research trends are covered, along with practical information on patient assessment, surgical techniques, clinical results, and the identification, avoidance and management of complications. Clinical images of both normal and rare sequelae of excimer laser surgery illustrate the text. Annotation copyrighted by Book News, Inc., Portland, OR.

This book is a review of past and current studies and future plans of the Laser Laboratory in Cincinnati and some of the contributions of laser research groups in other medical centers. Special thanks are due to the Directing Physicist of the Laser Labora tory, R. James Rockwell. Without his advice, constant supervision and corrections, this enthusiastic investigator would continue to upset even many more people than he has done already. The excuse, of course, is to stimulate much needed interest and controlled research and development of the laser for biology and medicine. The Associate Research Physicist, Ralph Schooley, has worked with many phases of laser research but especially in Q spoiling, Raman spectroscopy, and the almost alchemy of holography. Holography, as of now, provides many opportunities for Gumperson's Law, "If anything can go wrong, it will. " Sincere appreciation is expressed to the Surgeons in the Laser Labora tory, who have supplied clinical and investigative surgical supervision often under great difficulties, Dr. V. E. Siler and Dr. Bruce Henderson. We are grateful for help from the Directing Biologist of the Laser Labo ratory, Edmond Ritter, the Director of Laser Neurosurgery, Dr. Thomas Brown and the Professor of Neurosurgery, Dr. Robert McLaurin, for important and basic work in laser neurosurgery. Special thanks are given to Robert Meyer, who has given most of the treatments in careful and skillful fashion, and his associate, Robert Otten.

Different physical models for the Snoek-type relaxation in ternary systems (Fe-C-Me) are analyzed from the viewpoint of a distance of interatomic interaction taken into account: For non-saturated from the viewpoint of overlapping of interatomic interaction in b.c.c. alloys the physically sufficient and optimal for the computer simulation is the short-range model, which takes into account the interatomic interaction and the average amount of substitutional atoms in the first coordination shell, only. For high alloyed b.c.c. systems (i.e. with the overlapped interatomic interaction) the carbon atom undergoes an interaction of a few substitutional atoms simultaneously. That leads to the appearance of one broadened Snoek peak. Activation energy of such a peak is summed from the "elastic" and "chemical" interatomic interactions. Experimental results for alloys with b.c.c. solid solution structure and its computer simulations allow to introduce the new criterion for the high alloy state of monophase steels: the high alloyed state corresponds to the situation when substitutional atoms can not be considered any longer as the isolated atoms. From the viewpoint of mechanical spectroscopy this situation corresponds to the appearance of one broadened IF Snoek-type peak instead of two peaks existed for the steels with lower substitutional atom concentration.
