Book Description
Laser-enhanced ionization (LEI) is a type of optical spectrometrythat employs photoexcitation to ionize atoms selectively. Over thepast two decades, this method--originally known as the optogalvaniceffect--has been the object of extensive worldwide research and thesubject of numerous papers and published articles. Until now,however, no single volume has presented this wealth of theory anddata in a cohesive and accessible form. Laser-Enhanced Ionization Spectrometry fills this gap in theliterature. It synthesizes vast amounts of information previouslyavailable only through scattered research papers and covers everyaspect of the technology, from underlying principles and theory tomethodology and applications. This book examines the state of theart of LEI, compares it with other methods, and demonstrates howlaser-enhanced collisional ionization is especially well suited toanalytical atomic spectrometry. The contributors to this collaborative effort--from Russia,Australia, Europe, and the United States--clarify terminology,explain the inner workings of LEI, and offer derivations for bothidealized forms and realistic approximations. They also analyze thecapabilities and limitations of this technique as an analyticalmethod, including instrumentation, sources of noise, limits ofdetection, interferences, and applications. After concentrating largely on flame LEI as the most commonly usedmethod to derive LEI measurements, the discussion moves to thedevelopment of nonflame technologies for LEI. There is alsoextended coverage of the relationship between LEI and laser-inducedfluorescence, including an examination of the interplay oflaser-induced ionization and fluorescence techniques in differentatomic and molecular reservoirs. Laser-Enhanced Ionization Spectrometry places understanding,usefulness, and practical applications ahead of detailedderivations. For practicing analytical chemists andspectroscopists, it offers a clear and uncluttered approach to acomplex subject, as well as a fresh perspective on a still-emergingtechnology. This book sums up the present understanding and state of the art oflaser-enhanced ionization (LEI)-a unique but underutilized tool foranalytical atomic spectrometry. LEI possesses the special abilityto ionize atoms selectively. The text focuses on the role of thistechnology in analytical chemistry, and covers both theory andapplications in one complete, self-contained volume. Carefully crafted by leading experts from around the globe, withcontributions under six key headings, Laser-Enhanced IonizationSpectrometry * Draws on hundreds of research papers to create a comprehensivereference for LEI * Describes in depth how ions are produced, and how a signal isgenerated and detected * Provides an extensive and up-to-date compilation of published LEIdetection limits * Emphasizes basic understanding and practical applications ratherthan detailed derivations * Discusses terms and definitions and clears up sources ofconfusion in the field * Offers up-to-date coverage of instrumentation and applications * Evaluates the usefulness of LEI as an analytical tool * Deals with questions of limits of detection, interference, andnoise * Devotes an entire segment to nonflame technologies for LEI * Extends the discussion to fluorescence techniques and how theycan be interrelated with LEI in various atomic and molecularreservoirs

Book Description
This volume contains the Proceedings of a two-week NATO A.S.I. on "Analytical Laser Spectroscopy", held from September 23 to October 3, 1982 in Erice, Italy. This is the 9th annual course of Inter national School of Quantum Electronics organized under the auspices of the "E. Majorana" Center for Scientific Culture. The Advanced Study Institute has been devoted to the analytical applications of lasers in spectroscopy. Atomic and molecular spec troscopy is one of the research fields in which the use of lasers has had a dramatic impact. New spectral information, difficult or impos sible to gather by classical spectroscopy, extremely high resolution spectroscopy of atoms and molecules made possible by the overcoming of the Doppler effect, selective excitation and detection of single atomic and molecular quantum states are just few typical examples of how laser sources have revolutionized the field, offering challenging problems of both fundamental and applied nature. Among the possible approaches to a course on Analytical Laser Spectroscopy, the one which emphasizes the scientific and technologi cal aspects of the advanced laser techniques when applied to chemical analysis has been chosen. In fact, it reflects the new policy of the School to stress the advanced scientific and technological achieve ments in the field of Quantum Electronics. Accordingly, the course has given the broadest information on the ultimate performances of analytical laser spectroscopy techniques and the perspectives of their applications.

Book Description
Lasers have a wide and growing range of applications in medicine. Lasers for Medical Applications summarises the wealth of recent research on the principles, technologies and application of lasers in diagnostics, therapy and surgery.Part one gives an overview of the use of lasers in medicine, key principles of lasers and radiation interactions with tissue. To understand the wide diversity and therefore the large possible choice of these devices for a specific diagnosis or treatment, the respective types of the laser (solid state, gas, dye, and semiconductor) are reviewed in part two. Part three describes diagnostic laser methods, for example optical coherence tomography, spectroscopy, optical biopsy, and time-resolved fluorescence polarization spectroscopy. Those methods help doctors to refine the scope of involvement of the particular body part or, for example, to specify the extent of a tumor. Part four concentrates on the therapeutic applications of laser radiation in particular branches of medicine, including ophthalmology, dermatology, cardiology, urology, gynecology, otorhinolaryngology (ORL), neurology, dentistry, orthopaedic surgery and cancer therapy, as well as laser coatings of implants. The final chapter includes the safety precautions with which the staff working with laser instruments must be familiar.With its distinguished editor and international team of contributors, this important book summarizes international achievements in the field of laser applications in medicine in the past 50 years. It provides a valuable contribution to laser medicine by outstanding experts in medicine and engineering. - Describes the interaction of laser light with tissue - Reviews every type of laser used in medicine: solid state, gas, dye and semiconductor - Describes the use of lasers for diagnostics
