Press RELEASE

First overview of laser-induced damage

The newly published book „Laser-Induced Damage in Optical Materials“ gives a comprehensive overview of laser-induced damage effects in optical components. The book, edited by Prof. Dr. Detlev Ristau, Head of the Laser Components Department at the Laser Zentrum Hannover e.V. (LZH), is a collection of contributions by leading scientists in the field optical components and laser technology.

The main theme of the book is laser-induced damage, which can occur in the bulk, on the surface or in the coating of optical components, when higher laser powers are used. The book covers essential themes on high power laser coatings and materials against the background of fundamental damage mechanisms. It also covers important influencing variables during production of optical components and their applications.

Comprehensive Overview

In four sections, the book gives a fundamental introduction to theoretical and experimental methods, and summarizes strategies as well as current and further developments in the field of laser-induced damage. This reference work gives a previously unavailable overview of modelling trends, and it discusses measurement and evaluation techniques for threshold levels of laser-induced damage, concerning international standards.

Renowned Authors

“Laser-Induced Damage in Optical Materials” is currently the only comprehensive overview which includes the contributions of many renowned authors in this area. The list of authors includes:

Jonathan W. Arenberg, Stefan Borneis, Philippe Cormont, Angela Duparré, Luke A. Emmert, Vitaly Gruzdev, Anne Hildenbrand-Dhollande, Marco Jupé, Laurent Lamaignere, Angus H. Macleod, Klaus R. Mann, Christian Mühlig, Jérôme Néauport, Semyon Papernov, Wolfgang Riede, Detlev Ristau, Wolfgang Rudolph, Sven Schröder, Jianda Shao, Michelle Shinn, M.J. Soileau, Christopher J. Stolz, Wolfgang Triebel, Frank R. Wagner, Denny Wernham, Roger M. Wood

About Prof. Dr. Detlev Ristau

Prof. Dr. Detlev Ristau completed his studies of physics in the field of optical thin-film technology in 1982. Following this, he was awarded a grant at Rice University in Houston, Texas. In 1988 he received his PhD at the University of Hannover, and subsequently became Head of the Optical Coatings Group at the Institute for Quantum Optics. Since 1992 he has been responsible for the Laser Components Department of the LZH. His main research focus has been on the development and precise control of modern ion processes for the production of high-quality and stable optical coatings, as well as the characterization of optical components. In 2008 he qualified as a professor in these fields, and was appointed to be a professor for applied physics at the Leibniz Universität Hannover in 2010.

Laser Zentrum Hannover e.V. (LZH)

As an independent, non-profit research institute, the Laser Zentrum Hannover e.V. (LZH) stands for innovative research, development and consulting. The LZH is supported by the Lower Saxony Ministry for Economics, Labour and Transport and is dedicated to the selfless promotion of applied research in the field of photonics and laser technology. Founded in 1986, over 170 employees are now working for the LZH.

The focus of the LZH lies on the fields of optical components and systems, optical production technologies, and biomedical photonics. Interdisciplinary cooperation between natural scientists and mechanical engineers makes innovative approaches to challenges from the most different areas possible: from the development of components for specific laser systems to process developments for the most diverse laser applications, for example for medical technology or lightweight construction in the automotive sector. Seventeen spin off companies have emerged from the LZH up to now. Thus, the LZH has created a strong transfer between fundamental science, application oriented research, and industry.
