This book thoroughly covers the basics, process parameters, instruments, and applications of laser-induced breakdown spectroscopy (LIBS). It explores the interaction between focused laser radiation and the measuring object, detailing the impact of multiple pulses on material ablation, plasma dynamics, and emission. These insights lay the groundwork for a quantitative analysis of multi-element composition in solids, liquids, and gases. This updated and expanded second edition introduces exciting advances and novel insights into the field. In particular, it looks at many new LIBS applications encompassing bulk analysis of various materials, spatially resolved elemental imaging, and chemical identification of moving materials. The book also covers remote measurements across all physical states. It provides a detailed overview of LIBS instruments, including laboratory systems, industrial setups for inline process control as well as mobile measurement systems and systems for measurement over larger distances. The text delves into industrial applications of LIBS systems, showcasing their effectiveness in inline process control for improved process management and quality assurance. Practical examples and case studies demonstrate how LIBS contributes to this in industrial settings. Tailored for scientists, engineers, and students, the second edition maintains its commitment to delivering a solid introduction to the physics of LIBS. Simultaneously, it caters to the curiosity of those interested in the ongoing evolution of LIBS in industrial applications, blending foundational knowledge with the latest advancements in this dynamic field. The second edition of this standard work on LIBS contains 524 figures, 110 tables and cites 1085 references.
