N2 - Laser-induced breakdown spectroscopy (LIBS) has been used to map the distribution of particulate matter inside the plume created by laser ablation of a brass target. The spatial density distribution of the different components of the plume was determined in an attempt to reveal the mechanism of fractionation in the process of the laser ablation. In this experiment two Nd:YAG pulsed lasers were used. The first beam was focused on the target to generate a plume after breakdown of the surface. The second laser was focused on the plume and generated the second breakdown. The composition of the region probed by the second beam was determined by analyzing the spectral emission from the second breakdown. By scanning the probe time and position, the temporal and spatial evolution of the laser ablative plume could be discovered. Spatial and temporal fractionation was observed in brass plume.
