    Abstract

    Electron number density and temperature of soil plasma generated by laser ablation-fast pulse discharge plasma spectroscopic (LA-FPDPS) technique are studied. The experimentally measured line intensities of atomic and ionic states of silicon are used for electron temperature calculation from the Saha-Boltzmann equation. The electron number density is determined by using the Stark broadening of silicon 250.69 nm line emitted by the plasma. In comparison to the laser-produced plasma using the same laser energy, there is a considerable enhancement both in electron number density and electron temperature in plasma generated by LA-FPDPS of using a fast micro second discharge spark, which is consistent with the line intensity enhancement in LA-FPDPS.
