Description

Spatial characteristics of the plasma generated by 532-nm Nd:YAG laser irradiation of aluminum alloy in air were studied. The electron density inferred by measuring the Stark broadened line profile of Al II at 281.62 nm decreases with increasing distance from the target surface. The electron temperature was determined by using the Boltzmann plot method. Due to thermal conduction towards the solid target and radiative cooling of the plasma, as well as conversion of thermal energy to kinetic energy, the electron temperature decreases both at the plasma edge and close to the target surface.
