The dynamics of laser-ablated carbon plume propagation through different background Nitrogen pressure have been investigated with time and space-resolved emission spectroscopy. Results of temporal and spatial evolution of CI and CII emissions lines at 4267A and 2478A 4267A respectively under different nitrogen pressure show that there are two stages of expansion in accordance with shock wave and drag force model propagation model, Pub. in International Conference on Phenomena in Ionized Gases (26th), v4 p199-200, July 2003.

In this contribution we present time and space evolution of plasma parameters during ablation of titanium target in vacuum and at low nitrogen pressure using KrF laser. Electron density is measured from Stark Broadening of singly ionized species; electron temperature is determined from Boltzmann plot of lines intensities of the same species., Pub. in International Conference on Phenomena in Ionized Gases (26th), v4 p201-202, July 2003.
