Abstract
In this paper, the spatially-resolved characteristics, such as emission intensity, plasma temperature, and electron density, of femtosecond filament induced soil plasma were experimentally studied, and the spatial evolution of the limit of detection (LOD) was obtained along the filament channel propagation. The experiment results show that the spectrum intensity and LOD of Pb I 405.78 nm trended opposingly along the filament channel propagation, the maximum spectrum intensity and the minimum LOD are obtained at a certain distance along the filament channel, and the minimum LOD value for Pb element is 1.31 ± 0.04 ppm.
