In der Optoelektronik werden neue Forschungsergebnisse in rasantem Tempo in technische Entwicklungen und Anwendungen umgesetzt. Die seit 1973 alle zwei Jahre veranstaltete Kongre€messe Laser Opto-Elektronik ermöglicht einen Überblick über den aktuellen Stand. Das Programm von Laser 87 Opto-Elektronik umfa€te - wie seine Vorgänger - wieder ein breites Spektrum der Bereiche Technik und Medizin. In Basis-Seminaren wurden physikalische Grundlagen erläutert, Plenarvorträge vermittelten eine Übersicht über wichtige Fachgebiete, in Einzelvorträgen wurden neue Ergebnisse mitgeteilt. Der vorliegende Band "Laser/Optoelektronik in der Medizin 1987" enthält die Vorträge des 7. Internationalen Kongresses mit medizinischen Themenschwerpunkten.

This textbook is based on a course given by the first-named author to third and fourth year undergraduate students from physics, engineering physics and electrical engineering. The purpose is to introduce and explain some of the fundamental principles underlying laser beam control in optoelectronics, especially those in relation to optical anisotropy which is at the heart of many optical devices. The book attempts to give the reader the background knowledge needed to work in a laser, optoelectronic or photonic environment, and to manage and handle laser beam equipment with ease.In this edition, recent research results on modern technologies and instruments relevant to laser optoelectronics have been added to each chapter. New material include: chirped pulse amplification for petawatt lasers; optical anisotropy; physical explanations for group velocity dispersion, group delay dispersion, and third order dispersion; an introduction of different types of laser systems; and both optical isotropy and anisotropy in different types of harmonic generation.Theories based upon mode-locking and chirped pulse amplifications have become increasingly more important. It is thus necessary that students learn all these in a course devoted to laser optoelectronics. As such, Chapter 12 is now devoted to mode-locking and carrier-envelope phase locking. A new chapter, Chapter 13, which focuses on chirped pulse amplification has also been added.

The impact of lasers on spectroscopy can hardly be overestimated. Lasers re present intense light sources with spectral energy densities which may exceed those of i ncoheren t sources by severa 1 orders of magnitude. Furthermore be cause of their extremely small bandwidth, single-mode lasers allow a spectral resolution which far exceeds that of conventional spectrometers. Many experi ments which could not be done before the application of lasers because of lack of intensity or insufficient resol ution are readily performed wi th lasers. Now several thousands of laser lines are known which span the whole spec tral range from the vacuum-ultraviolet to the far-infrared region. Of parti cular interest are the continuously tunable lasers which may in many cases replace wavelength-selecting elements, such as spectrometers or interferome ters. In combination with optical frequency mixing, techniques such conti nuously tunable monochromatic coherent light sources are available at nearly any desired wavelength above 100 nm.

Picosecond Optoelectronic Devices reviews the major developments in the field of picosecond optoelectronics. This book discusses the picosecond pulse generation with semiconductor diode lasers; gigabit optical pulse generation in integrated lasers and applications; and picosecond photoconductors. The picosecond optoelectronic devices based on optically injected electron-hole plasma; pulse forming with optoelectronic switches; and high-power picosecond switching in bulk semiconductors are also elaborated. This text likewise discusses the sub-picosecond electrical sampling and applications; InP optoelectronic switches; and picosecond chronography. Other topics include the picosecond optical control of transferred-electron devices; optoelectronic switch for pulsed power; and responses of TEDs to picosecond optical pulses. This publication is a good source for electrical engineers and researchers conducting work on picosecond optoelectronics.
