Pulsed laser induced plasma (LIP) has a very short temporal existence. Due to the transient nature of the produced LIP, with a fast evolution of its characteristic parameters, these parameters are heavily dependent on the irradiation conditions such as incident laser intensity, irradiation spot size, ambient gas composition and pressure. It is also true that these parameters vary drastically with axial or radial distance from the target surface under the same irradiation. In the present work depth profiling measurements of gold film onto copper substrate have been performed and the effect of changing laser irradiance by changing the working distance on both electron density and electron temperature has been also studied.
