A cerium oxide sample was ablated by 2nd harmonic radiation of Nd:YAG laser at a power density of 0.1 GW/cm$$^{2}$$. The velocities of the ablated atomic and ionic species were measured with the resonance absorption spectroscopy. It was found that the ablated ionic plume consists of at least two components having different velocities whereas the ablated atomic plume has roughly a single component. The flow velocity perpendicular to the sample surface in vacuum was determined to be 3.5 km/s for neutral atoms, and 4.7 km/s and 9.3 km/s for singly charged ions. From detailed plume evolution in ambient gas with several pressures we obtained some experimental conditions suitable for isotope analysis of atomic cerium.
