This updated and enlarged new edition presents a comprehensive and dedicated overview of the fundamentals and modern applications of coherent optics. Starting with the basic principles of coherence, the authors give detailed insights into the theory and applications of interferometry, holography, Fourier optics, and nonlinear optical phenomena. Especially, the chapters on current topics in nonlinear optics provide an understanding of modern implementations. To name just a few, sections on the generation and measurement of ultrashort laser pulses, optical gating, coherence tomography, digital holography, and advances in fibre optics have been added. Numerous examples and exercises with complete solutions help the readers to deepen their knowledge. This completely revised edition is intended for advanced students and active scientists working in this field.

Since the advent of the laser, coherent optics has developed at an ever increasing pace. There is no doubt about the reason. Coherent light, with its properties so different from the light we are surrounded by, lends itself to numerous applications in science, technology, and life. The bandwidth of coherent optics reaches from holography and interferometry, with its gravitational wave detectors, to the CD player for music, movies, and computers; from the laser scalpel, which allows surgical cutting in the interior of the eye without destruction of the layers penetrated in front of it, to optical information and data processing with its great impact on society. According to its importance, the foundations of coherent optics should be conveyed to students of natural sciences as early as possible to better prepare them for their future careers as physicists or engineers. The present book tries to serve this need: to promote the foundations of coherent optics. Special attention is paid to a thorough presentation of the fundamentals. This should enable the reader to follow the contemporary literature from a firm basis. The wealth of material, of course, makes necessary a restriction of the topics included. Therefore, from the main areas of optics, wave optics and the classical description oflight is given most ofthe space available. The book starts with a quick trip through the history of physics from the viewpoint of optics.

"Koh{rente Optik" beschreibt ausgehend von den Grundbegriffen der Koh{renz und seiner Messung die Grundlagen f}r Interferometrie, Holographie und Fourieroptik sowie die me technischen Methoden dieser Gebiete. V-llig neuartige Anwendungen werden durch das Gebiet der nichtlinearen Optik erschlossen: der Laser und seine nichtlineare Dynamik, das Wellenmischen, die Phasenkonjugation und die optische Nachrichtentechnik und Datenverarbeitung. Durch die verst{ndliche und anschauliche Darstellung mit vielen Beispielen und ]bungsaufgaben eignet sich das Lehrbuch sowohl als Vorlesungsbegleiter als auch zum Selbststudium. Ein Anhang zu Fouriertransformation und digitaler Hologrammberechnung sowie die L-sungen zu den etwa 50 ]bungsaufgaben runden das Buch ab.
