Abstract

The first free electron density radial profiles of a sodium plasma created by laser resonance saturation are reported. The measurements were based on Stark broadening, of the 4²D–3²P multiplet and reveal the formation of a conically shaped plasma along the path of the laser pulse, which can be attributed to strong absorption of the laser pulse along the ionization path.
