Book Description
The optoacoustic method has by now an almost one-centurY-long history of appl ication in spectroscopy, but it was only with the advent of the laser that it became a convenient and effective method among the vast family of spectroscopy techniques. The great variety of these techniques is capable of tackling most diversified tasks, such as the achievement of a high sensitiv ity and a high spectral or temporal resolution. The optoacoustic method is one of the simplest and most versatile ways to attain a high sensitivity for both gaseous and condensed media. It is precisely for this reason that the method has found wide use, and that we have decided to publish a mono graph reviewing the information on this method available in the literature and gathered by us at the Institute of Spectroscopy during the past few years. We hope that such a systematic exposition of the material scattered throughout numerous scientific journals will be of use to many potential readers. The reader will undoubtedly notice the absence in our monograph of references to some recent works, but unfortunately, this is inevitable when the translation and publication of a book in a foreign language takes sev eral years. Nevertheless, we tried our best to cover the entire field from the material available to us, but unfortunately, some recent publications might be missing due to the time lag for the translation and publication in a language foreign to us.

Book Description
Optoacoustic Spectroscopy and Detection discusses the fundamental principles and practice of optoacoustic spectroscopy. This book serves as a basis for evaluation of the feasibility of using such techniques in specific instances. Organized into eight chapters, this book starts with an overview of the detection and identification of gas contaminants, which is necessary to understand the physical description of the generation and measurement of the optoacoustic signal. This text then provides an understanding of the optoacoustic effect on a molecular scale and describes the energy transfer processes and estimates of the lifetimes of vibrationally excited states. Other chapters consider the options available to the researcher in the selection of optoacoustic system design. This book discusses as well the capabilities and limitations of various optoacoustic system designs. The final chapter deals with the technique used for exploring the absorption spectra of substances, including powders, gels, adsorbed films, and organic tissues. This book is a valuable resource for researchers and graduate students engaged in the study of optoacoustic spectroscopy.

Book Description
Trace gas sensing technologies are widely used in many applications, such as environmental monitoring, life science, medical diagnostics, and planetary exploration. On the one hand, laser sources have developed greatly due to the rapid development of laser media and laser techniques in recent years. Some novel lasers such as solid-state, diode, and quantum cascade lasers have experienced significant progress. At present, laser wavelengths can cover the range from ultraviolet to terahertz, which could promote the development of laser gas sensing technologies significantly. On the other hand, some new gas sensing methods have appeared, such as photothermal spectroscopy and photoacoustic spectroscopy. Laser spectroscopy-based gas sensing techniques have the advantages of high sensitivity, non-invasiveness, and allowing in situ, real-time observation. Due to the rapid and recent developments in laser source as well as the great merits of laser spectroscopy-based gas sensing techniques, this book aims to provide an updated overview of the state-of-the-art laser gas sensing technologies.
