Breakdown Spectroscopy Stimulate by Laser for Silver Plasma

Abstract

This article focused on the OES (optical emission spectra) for silver (Ag) plasma by the stimulate of laser breakdown spectroscopy process. The intensities of emission line also parameters for plasma were measured in order to detect the specific relation of laser pulse energies. Density number of electron (ne), as well temperature (Te) have been calculated by Blotzmann polt process either by McWhirter criterion. Measured values of (ne) and (Te) are in the range of (6064 to 4507K) and (ne) is (2.3x1017 to 3.7x1017 cm-3) at the fundamental wavelength (1064nm), and for case of (Ag- bulk) the value of electron temperature was (6564, 5228 to 4507 K) The number of electron density (9.36x1016 to 1.19x1017cm-3). The common trends of the results are the temperature of electron (Te) leads to increase precipitously due to the increase of laser pulse energy. Since, as the energy increases the electrons density increases.
