Interfaces Under Laser Irradiation (Hardcover, 1987 ed.): L.D. Laude, D. Bauerle, M. Wautelet Interfaces Under Laser Irradiation (Hardcover, 1987 ed.)

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."

Der erste Laser wurde bereits Anfang 1960 als Laborgerat gebaut. Erst in den vergangenen zwanzig Jahren ist es aber gelungen, Laser zuverlassiger, stabiler, kompakter und billiger zu erzeugen. Seither schreitet der Siegeszug von Lasern unaufhaltsam voran. Viele "technische Errungenschaften," insbesondere in der Produktionstechnik, basieren auf dem Einsatz von Lasern. Die Lasertechnik ist heute ein eigenstandiges Fachgebiet.
Mit der Entwicklung langlebiger stabiler und billiger Halbleiterlaser in Kombination mit moderner Optik sowie einer leistungsfahigeren Elektronik und der standig verbesserten Glas- und Polymerfasertechnik, ist eine weitere ganz neue Disziplin entstanden: die Photonik. Die Photonik befasst sich mit neuen optischen Technologien zur Erzeugung, Verstarkung, ubertragung, Steuerung und Messung von Licht.
Die Photonik und die Lasertechnologie haben viele Fachgebiete revolutioniert oder erst neu entstehen lassen. Anwendungen der Photonik umfassen heute die Unterhaltungs-, Druck- und Informationstechnologie, sowie viele Bereiche der industriellen Fertigungs-, Mess- und Umwelttechnik, aber auch der Biotechnologie, Medizin und Kunst.
Das vorliegende Buch soll neugierige aber auf diesem Gebiet nicht unbedingt vorgebildete Leser an den faszinierenden Entwicklungen der Photonik und der Lasertechnologie teilhaben lassen und ihnen ein besseres Verstandnis der einzigartigen Eigenschaften von Laserlicht und dessen zahlreichen Anwendungen in der Lasertechnik und Photonik vermitteln.

Laser processing is now a rapidly increasing field with many real and potential applications in different areas of technology such as micromecha- nics, metallurgy, integrated optics, and semiconductor device fabrication. The neces s ity for such soph i st i cated 1 i ght sources as 1 asers is based on the spatial coherence and the monochromaticity of laser light. The spatial coherence permits extreme focussing of the laser light resulting in the availability of high energy densities which can be used for strongly loca- lized heat- and chemical-treatment of materials, with a resolution down to 1 ess than 1 lJIll. When us i ng pul sed or scanned cw-l asers, 1 oca 1 i zat i on in time is also possible. Additionally, the monochromaticity of laser light allows for control of the depth of heat treatment and/or selective, nonthermal bond breaking - within the surface of the material or within the molecules of the surrounding reactive atmosphere - simply by tuning the laser wavelength. These inherent advantages of laser light permit micromachining of materials (drilling, cutting, welding etc. ) and also allow single-step controlled area processing of thin films and surfaces. Processes include structural transformation (removal of residual damage, grain growth in polycrystalline material, amorphization, surface hardening etc. ), etching, doping, alloying, or deposition. In addition, laser processing is not 1 imited to planar substrates.
