Sažetak
The laser-induced plasma plume was probed by the cavity ring-down spectroscopy. Model is developed to perform forward convolution of atomic absorption line profile measurement. It accounts for laser-induced plasma characteristics such as anisotropy of the plume and velocity distributions of ablated particles and the cavity ring-down features such as geometry and time selectivity. The absorption lineshapes of atomic transitions are calculated and discussed for sets of parameters. Calculated line profiles are fitted to experimental line profiles obtained from nanosecond-laser ablation of titanium target providing data about plume dynamics.
