Abstract

Laser induced plasma spectroscopy is beginning to find useful applications in the real time in situ detection of particulates and aerosols suspended in gases. Although the technique is almost 40 years old, it has become increasingly practical for this application during the last decade due to the development of more reliable lasers and optical detection systems, an improved understanding of the physical processes involved, and new data collection and analysis strategies. There is a pressing need for such detection techniques for industrial process and atmospheric monitoring. In this review, we examine literature concerned with the process of optical breakdown by focused lasers in gases, the role of particles in this process, and the characterization of particles using laser induced plasmas.
