Fundamental Physics and Applications of Laser-Induced Breakdown

In this workshop talk, we will explore the fundamental physics and diverse applications of Laser-Induced Breakdown. LIB is a robust diagnostic technique that utilizes high-intensity laser pulses to create a plasma, enabling detailed elemental analysis of various materials. This talk will delve into the underlying physical mechanisms of laser-induced breakdown, including plasma formation, energy absorption, and emission processes. By understanding these fundamental aspects, we can better leverage LIB for precise and accurate measurements.

We will also discuss the wide-ranging applications of LIB across different fields. Key applications include real-time monitoring of combustion processes, analysis of material ablation in high-speed flows, and detection of trace elements in atmospheric studies. The versatility of LIB allows for minimal sample preparation and rapid, in-situ diagnostics, making it an invaluable tool in both research and industrial settings.

Additionally, the talk will highlight the integration of LIB with other diagnostic techniques such as Resonance Enhanced Multiphoton Ionization (REMPI), showcasing how these combined methods enhance the measurement of species concentrations and temperatures in complex environments. Through advanced laser diagnostics, we aim to advance our understanding of high-temperature and high-pressure phenomena, contributing to the development of more efficient and reliable technologies in various engineering systems.
