Investigates the atomic density distribution of a laser ablation-induced niobium (Nb) vapor plume by linear absorption spectroscopy. Schematic description of the experimental apparatus; Population density of Nb atoms in the vapor plume as a function of radial distance; Variation of density at the center of the plume as a function of height above target surface.
