Modeling of Cavity Ring-Down Spectroscopy Characterization of Laser-Induced Plasma Plume

Dynamics of laser-induced plasma plume studied by cavity ring-down spectroscopy (CRDS) was simulated by a numerical model. Velocity distribution and anisotropy of the plume with temporal and geometrical characteristics of CRDS were included. Behavior of spectral lineshapes was studied in respect to various experimental parameters.
