For a host of reasons, nonlinear optical spectroscopy is a valuable tool for biochemical applications where minimally invasive diagnostics is desired. Biochemical Applications of Nonlinear Optical Spectroscopy presents the latest technological advances and offers a perspective on future directions in this important field. Written by an international panel of experts, this volume begins with a comparison of nonlinear optical spectroscopy and x-ray crystallography. The text examines the use of multiphoton fluorescence to study chemical phenomena in the skin, the use of nonlinear optics to enhance traditional optical spectroscopy, and the multimodal approach, which incorporates several spectroscopic techniques in one instrument. Later chapters explore Raman microscopy, third-harmonic generation microscopy, and non-linear Raman microspectroscopy. The text explores the promise of beam shaping and the use of broadband laser pulse generated through continuum generation and an optical pulse shaper. Lastly, the book discusses the effects of spatial beam shaping on the generated nonlinear Raman signals in a tightly focused geometry and provides insight into the extension of nonlinear optical spectroscopy to the nanoscale through the use of plasmonic tip-enhanced arrangement. With novel experimental approaches to this technology expanding day-by-day, the book’s balanced coverage from a wide range of international contributors not only elucidates important achievements, but also outlines future directions in this dynamic and promising field.

Developments in optical spectroscopy have taken new directions in recent decades, with the focus shifting from understanding small gas phase molecules towards applications in materials and biological systems. This is due to significant interest in these topics, which has been facilitated by significant technological developments.Absorption, luminescence and excited state energy transfer properties have become of crucial importance on a large scale in materials related to light-harvesting in organic and inorganic third generation solar cells, for solar water splitting, and in light emitting diodes, TV screens and many other applications. In addition, Förster resonance energy transfer can be used as a ruler for the characterisation of the structure and dynamics of DNA, proteins and other biomolecules via labelling with fluorescing markers.This advanced textbook covers a range of these applications as well as the basics of absorption, emission and energy transfer of molecular systems in the condensed phase, in addition to the corresponding behaviour of metal nanoparticles and semiconductor quantum dots. Technical experimental requirements, aspects to avoid interfering perturbations and methods of quantitative data analysis make this book accessible and ideal for students and researchers in physical chemistry, biophysics and nanomaterials.

"Extreme Photonics & Applications" arises from the 2008 NATO Advanced Study Institute in Laser Control & Monitoring in New Materials, Biomedicine, Environment, Security and Defense. Leading experts in the manipulation of light offered by recent advances in laser physics and nanoscience were invited to give lectures in their fields of expertise and participate in discussions on current research, applications and new directions. The sum of their contributions to this book is a primer for the state of scientific knowledge and the issues within the subject of photonics taken to the extreme frontiers: molding light at the ultra-finest scales, which represents the beginning of the end to limitations in optical science for the benefit of 21st Century technological societies. Laser light is an exquisite tool for physical and chemical research. Physicists have recently developed pulsed lasers with such short durations that one laser shot takes the time of one molecular vibration or one electron rotation in an atom, which makes it possible to observe their internal electronic structure, thereby enabling the study of physical processes and new chemical reactions. In parallel, advances in micro- and nano-structured photonic materials allow the precise manipulation of light on its natural scale of a wavelength. Photonic crystals, plasmons and related metamaterials - composed of subwavelength nanostructures - permit the manipulation of their dispersive properties and have allowed the experimental confirmation of bizarre new effects such as slow light and negative refraction. These advances open a vista on a new era in which it is possible to build lasers and engineer materials to control and use photons as precisely as it is already possible to do with electrons. http://www.photonics.uottawa.ca/nato-asi-2008/

This new handbook covers the world of biophotonics not only geographically -- with the editors coming from different continents -- but also in terms of content, since the authors come from the whole spectrum of biophotonic basic and applied research. Designed to set the standard for the scientific community, these three volumes break new ground by providing readers with the physics basics as well as the biological and medical background, together with detailed reports on recent technical advances. The Handbook also adopts an application-related approach, starting with the application and then citing the various tools to solve the scientific task, making it of particular value to medical doctors. Divided into several sections, the first part offers introductory chapters on the different fields of research, with subsequent parts focusing on the applications and techniques in various fields of industry and research. The result is a handy source for scientists seeking the basics in a condensed form, and equally a reference for quickly gathering the knowledge from neighboring disciplines. Absolutely invaluable for biophotonic scientists in their daily work.
