A volume in the Progress in Optics series, the papers in this book cover a range of topics, including: anamorphic beam shaping for laser and diffuse light; ultra-fast all-optical switching in optical networks; generation of dark hollow beams and their application; and two-photon lasers.

This book presents recent and important developments in the field of terahertz radiation, with a particular focus on pulsed terahertz radiation. Situated in the gap between electronics and optics, the terahertz frequency range of the electro-magnetic spectrum has long been neglected by scientists and engineers due to a lack of efficient and affordable terahertz sources and detectors. The advent of femtosecond lasers in the 1980s and photoconductive switches in 1984 have made the terahertz gap accessible, while at the same time advances in electronics and optics have made it narrower....

Over the last decades, the use of lasers in artwork conservation has became an important tool for many conservators, scientists, architects and other experts, who are involved in the care of monuments and artefacts or applied laser technology. Professor Costas Fotakis first brought together restorers and scientists in 1995 to discuss the potential of lasers in art conservation. The field of "Lasers in the Conservation of Artworks" has since gained considerably in importance, and nowadays restorers and laser scientists work closely together to develop new applications. Furthermore a large...

Organic semiconductors offer unique characteristics which have prompted the application of organic semiconductors and their devices in physical, chemical, and biological sensors. This book covers this emerging field by discussing both optically- and electrically-based sensor concepts. Novel transducers based on organic light-emitting diodes and organic thin-film transistors, as well as systems-on-a-chip architectures are presented. Functionalization techniques are also outlined.

Optics--a field of physics focusing on the study of light--is also central to many areas of biology, including vision, ecology, botany, animal behavior, neurobiology, and molecular biology. The Optics of Life introduces the fundamentals of optics to biologists and nonphysicists, giving them the tools they need to successfully incorporate optical measurements and principles into their research. Sonke Johnsen starts with the basics, describing the properties of light and the units and geometry of measurement. He then explores how light is created and propagates and how it interacts...
