Book Description
The book reviews the dramatic recent advances in the use of optical resonators for high sensitivity and high resolution molecular spectroscopy as well as for chemical, mechanical and physical sensing. It encompasses a variety of cavities including those made of two or more mirrors, optical fiber loops, fiber gratings and spherical cavities. The book focuses on novel techniques and their applications. Each chapter is written by an expert and/or pioneer in the field. These experts also provide the theoretical background in optics and molecular physics where needed. Examples of recent breakthroughs include the use of frequency combs (Nobel prize 2005) for cavity enhanced sensing and spectroscopy, the use of novel cavity materials and geometries, the development of optical heterodyne detection techniques combined to active frequency-locking schemes. These methods allow the use and interrogation of optical resonators with a variety of coherent light sources for trace gas detection and sensing of strain, temperature and pressure.

Book Description
This second edition of Differential Optical Absorption Spectroscopy (DOAS) has been meticulously updated to enhance its clarity and relevance. Responding to the growing popularity of DOAS techniques, this edition expands the sections on atmospheric radiative transfer, covering new and crucial topics such as the ring effect and profile inversion techniques. Additionally, the book presents a comprehensive array of DOAS applications and techniques, ranging from research applications using imaging and satellite DOAS to emission monitoring from volcanoes and industrial facilities by LED long-path DOAS, as well as mobile MAX-DOAS and Cavity-Enhanced DOAS. The discussion of DOAS retrieval algorithms has significantly broadened to incorporate the latest developments, particularly pertinent to the satellite community. The first part of the book provides a thorough review of atmospheric chemistry, radiation transport, and optical spectroscopy fundamentals, serving as a crucialfoundation for a detailed exploration of the principles underpinning DOAS. The subsequent part delves into the design, application, and assessment of DOAS instruments, accompanied by a comprehensive guide to result interpretation. The book also embraces the application of DOAS in imaging trace gas distributions through ground, aircraft, and satellite-based instruments. Structured with the needs of graduate students and researchers with a foundational background in environmental physics in mind, this book serves as an invaluable resource. It particularly caters to researchers engaged in atmospheric chemistry, pollution monitoring, and volcanology.
