Dynamics of Carbon Plasma Induced by an Excimer Laser in Nitrogen Environment

Abstract

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
