The spatial distribution of carbon species produced by laser ablation of a graphite target was studied using laser induced fluorescence imaging and optical emission spectroscopy. Two-dimensional fluorescence of ambient gases at various pressures, laser fluences and ablation area were used to measure spatial density profiles of C2. The yield of C2 was large at center of the plume and near the target surface while that of C3 in argon gas increased at higher gas pressure and longer delay times after ablation.
