In the scenario, nonlinear optics is very important due the large number of applications such as optical limiting, image processing and nonlinear devices etc. There are considerable research efforts to study the mechanisms of optical power limiting, synthesize new materials and develop devices with advanced properties. An optical limiter is a device that strongly attenuates optical beam to a threshold level at high intensity while exhibits linear transmittance at low intensity. Such devices are used for protecting human eyes and optical sensors from damage due to exposure to intense radiation. The search for efficient optical limiters has lead to the study of various materials. This book is dealing with the problem of new materials and characterize them using Z-scan technique, it will be very helpful for the researchers and students who are working in the area of Nonlinear Optics.

Optical properties are among the most fascinating and useful properties of nanomaterials and have been extensively studied using a variety of optical spectroscopic techniques. A basic understanding of the optical properties and related spectroscopic techniques is essential for anyone who is interested in learning about nanomaterials of semiconductors, insulators or metal. This is partly because optical properties are intimately related to other properties and functionalities (e.g. electronic, magnetic, and thermal) that are of fundamental importance to many technological applications, such as energy conversion, chemical analysis, biomedicine, optoelectronics, communication, and radiation detection.Intentionally designed for upper-level undergraduate students and beginning graduate students with some basic knowledge of quantum mechanics, this book provides the first systematic coverage of optical properties and spectroscopic techniques of nanomaterials.

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.

This text describes the technique of optical spectroscopy applied to problems in condensed matter physics. It relates theoretical understanding to experimental measurement, including discussion of the optical spectroscopy of inorganic insulators, with many illustrative examples. Symmetry arguments are developed from a formal group theoretical basis and are frequently used, and a special effort is made to treat the subject of lattice vibrations and to show how these can affect the spectroscopic properties of solids. The elements of laser theory are developed, and the authors also explore the use of optically detected magnetic resonance techniques for the investigation of semiconducting materials.

Nanomaterials are mainly categorized into three groups: fundamental building blocks, dispersions or composites of building blocks in randomly ordered matrices, and spatially resolved, ordered nanostructures. Today, nanomaterials that offer some unique optical properties may find application as pure materials or may be integrated into larger structures. This book presents examples of both pure and composite materials that include organic–inorganic nanocomposites and quantum dots embedded into different matrices for various applications in modern nanotechnology. This edition has been thoroughly revised and updated with the most recent developments in the field. The newly added introductory paragraphs will help students and young researchers in better understanding the chapters. The new sections on frequently used physical constants and units conversions as well as the updated bibliography add to the book’s utility. This textbook is unique compared with its counterparts in the market in respect of its scope as it contains introductory sections to the important topics on nanomaterial optics. This feature broadens its readership from engineers and researchers working in the field of materials science and optics, to lecturers, graduate students, and beginners who want to deepen their knowledge in nanomaterial optics.
