The chapters present the problems of stresses and strains induced in metals and nonmetals in the processes of laser heating, analyze the results, offer the ways of laser treatment that dispense with subsequent machining operations, and describe the basic approaches to increase the strength of materials during laser heating. Other topics include the practical methods of implementing the processes of laser welding, cutting, hardening, alloying, and cladding (hardfacing). Basics of Laser Material Processing is designed for scientific workers and for those students in senior- and graduate-level courses.

Ob zur Oberflachenanalytik oder zur Oberflachenbearbeitung - die Einsatzgebiete von Lasern in der Materialwissenschaft werden standig erweitert. Dabei ablaufende Prozesse beschranken sich gelegentlich auf einfaches Erwarmen und Schmelzen, haufig finden jedoch kompliziertere Vorgange wie die Bildung von Plasma oder kollektive Anregungen statt. Verschiedenste Techniken, die zugehorigen physikalischen Grundlagen und alle wichtigen Prozesse beschreibt dieses Buch, wobei auch neueste Themen wie ultrakurze Laserpulse oder die nichtlineare Oberflachenspektroskpoie zur Sprache kommen.

New chapters and updates highlight the second edition of Laser Safety: Tools and Training. This text provides background information relating to lasers and laser safety, and examines the components of laser work and laser safety from a different perspective. Written by a working laser safety officer, the book considers ways to keep users, as well as those around them, safe. The author encourages readers to think beyond protective eyewear. As it relates to safety, he determines that if eyewear is required, then the laser system is not ideal. This book factors in optics, the vibration elements of the optical table, the power meter, and user training, elements that are not commonly considered in the context of laser safety. It presents ways for users to evaluate the hazards of any laser procedure and ensure that they are following documented laser safety standards. The material serves as a fundamental means or road map for laser users seeking to utilize the safest system possible. What’s New in the Second Edition: The second edition provides an inclusion of the Z136.8 Research Laser Standard, and offers updates and an explanation of eye exposure limits (MPE), presents new cases studies, and presents practical example images.

The recent years have been characterized by stormy social protests throughout the world. These protests have some commonalities, but at the same time, their sociopolitical, psychological, and economic contexts differ essentially. An important class of such protests is known as color revolutions. The analysis of these events in social and political literature is characterized by huge diversity of opinions. We remark that the sociopolitical perturbations under consideration are characterized by the cascade dynamics leading to the exponential amplification of coherent social actions. In quantum physics, such exponential and coherent amplification is the basic feature of laser’s functioning. (“Laser” is acronym for light amplification by stimulated emission of radiation). In this book we explore the theory of laser to model aforementioned waves of social protests, from color revolutions to Brexit and Trump’s election. We call such social processes Stimulated Amplification of Social Actions (SASA), but to keep closer to the analogy with physics we merely operate with the term “social laser.”

Laser cleaning is very important for modern high technology. It is used, or considered for use in the fabrication of printed circuit boards, in the production of dynamic random access memory (DRAM), in lithography and epitaxial growth, for the removal of contaminations during via-hole production, and for the cleaning of micro-optical and micro-mechanical components.This invaluable book presents the mechanics of the cleaning processes, experimental results, and different applications, including laser cleaning of art. It contains review articles by leading specialists in laser cleaning who participated in the 1st International Workshop on Laser Cleaning, held in Singapore in 2001.

together with the oncologist. For man, the laser must be moved out of the laboratory into the operating room. At present, its true position in the cancer therapy program is not yet known. The greatest attention is being directed to melanoma because of the tremendous energy adsorption capabilities of this heavily pigmented tumor. The next area of interest is in uncommon and com mon tumors of blood vessels. Here, too, the color factor influences to a signifi cant degree the absorption of the laser. Multiple accessible malignancies are treated also by the laser chiefly to compare the effect here with other modalities of therapy. Finally, as a type of therapy of desperation, lasers are used in the treatment of metastatic lesions. This then, is the brief introduction to the study of the current status of laser cancer research. Intense, difficult and cooperative research of the next few years will determine the role of the laser, an "optical knife", as an investi gative or therapeutic instrument.
