Known and developed over the past twenty five years, lasers have been experimented in a variety of processes with an uneven success. Apart from fundamental physics experiments in which the various aspects of coherence are systematically exploited, applications in the field of Materials Science have been scattered recently over so many situations that it is apparently difficult today to conceive a comprehensive interpretation of all physical processes encountered. In some domains of research like photochemistry, development has been fast and rather self-supporting. In others, like solid-state processing, progress has been either very specific or deviated towards marginal applications, or else emerged as a joint-venture between physicists and chemists. This yielded a number of professional meetings, where day-to-day research activities are presented. In 1982, the Cargese ASI on "Cohesive properties of semiconductors under laser irradiation" was one of such meetings at which a prospective of the field was discussed at length in ebullient round-table sessions. Quoted from the proceedings, "the Institute helped to discern clearly the limits of existing theoretical approaches and the directions along which work is urgently needed within the next few years". Four years have passed and the field has literally explo ded. It must be mentioned that some of the most striking developments over the past two years were accurately predicted at the Institute in Cargese.

The impact of Materials Science in our environment has probably never been as massive and decisive as it is today. In every aspect of our lives, progress has never been so dependent on the techniques involved in producing ever more sophisticated materials in ever larger quantities, nor so demanding for technologists to imagine novel processes and circumvent difficulties, or take up new challenges. Every technique is based on a physical process which is put into practice and optimized. The better we know that process, the better the optimization, and more powerful the technique. Laser processing of materials is inscribed in that context. As soon as powerful coherent light sources were made available, it was realized that such intense sources of energy could be used to "heat, melt and crystallize" materials, i.e., to promote phase transitions in atomic systems. As early as 1964, attempts in that direction were made but received very little (if any) attention. Reasons for this lack of interest were several. For one thing, laser technology was not fully developed, so that the process offered poor reliability and no versatility. Also, improving the existing techniques was believed to be sufficient to meet the needs of the time, and there was no real motivation to explore new ways. Finally, and more important, the fundamentals of the physics behind the scenes were, and continue to be, way out of the runni~g stream.

The papers in this volume cover all aspects of laser assisted surface processing ranging from the preparation of high-Tc superconducting layer structures to industrial laser applications for device fabrication. The topics presented give recent results in organometallic chemistry and laser photochemistry, and novel surface characterization techniques. The ability to control the surface morphology by digital deposition and etching shows one of the future directions for exciting applications of laser surface processing, some of which may apply UV and VUV excitation. The understanding of elementary proceses is essential for the design of novel deposition methods, with diamond CVD being an outstanding example. The high quality of these contributions once again demonstrates that the E-MRS is an efficient forum for interaction between research workers and industry.

Laser Processing and Chemistry gives an overview of the fundamentals and applications of laser-matter interactions, in particular with regard to laser material processing. Special attention is given to laser-induced physical and chemical processes at gas-solid, liquid-solid, and solid-solid interfaces. Starting with the background physics, the book proceeds to examine applications of laser techniques in micro-machining, and the patterning, coating, and modification of material surfaces. This fourth edition has been revised and enlarged to cover new topics such as 3D microfabrication, advances in nanotechnology, ultrafast laser technology and laser chemical processing (LCP). Graduate students, physicists, chemists, engineers, and manufacturers alike will find this book an invaluable reference work on laser processing.

Laser-Assisted Microtechnology introduces the principles and techniques of laser-assisted microtechnology with emphasis on micromachining of thin films, microprocessing of materials, maskless laser micropatterning and laser-assisted synthesis of thin-film systems. The experimental and theoretical physico-chemical basis of every technological process is presented in detail. On the basis of some characteristic examples of applications, the capabilities of the technological methods as well as the optimum conditions for their realization are discussed. In this second edition, besides the actualization of the literature, a new chapter concerning the laser-assisted wet chemical micro etching, has been added. This is a new method for direct 3D-micro structuring of solids, with a number of potential applications.

The formation, deformation, and break-up of liquid interfaces are ubiquitous phenomena in nature. In the present book the authors discuss the deformation of a liquid interface produced by optical radiation forces. Usually, the bending of such an interface by the radiation pressure of a c.w. laser beam is weak. However, the effect can be enhanced significantly if one works with a near-critical phase-separated liquid mixture, whereby the surface tension becomes weak. The bending may in this way become as large as several tenths of micrometers, even with the use of only moderate laser power. This near-criticality is a key element in our experimental investigations as reviewed in the article. The effect is achieved by working with a micellar phase of microemulsions, at room temperature. The authors give a brief survey of the theory of electromagnetic forces on continuous matter, and survey earlier experiments in this area, such as the Ashkin-Dziedzic optical radiation force experiment on a water/air surface, the Zhang-Chang experiment on the laser-induced deformation of a micrometer-sized spherical water droplet, and the experiment of Sakai et al. measuring surface tensions of interfaces in a non-contact manner. Thereafter, the authors survey results they obtained in recent years by performing experiments on near-critical interfaces, such as interface bending in the linear regime, stationary large deformations of liquid interfaces, asymmetric pressure effects on interfaces under intense illumination, non-linear deformations, and laser-sustained liquid columns.
