Influence of the pressure of a gaseous atmosphere on the characteristics of the emission spectra of a laser plasma generated on the surfaces of solid targets

The intensities, widths, and shifts of the centres of the emission lines of a laser plasma generated on the surfaces of solid targets were determined experimentally as a function of the ambient gas pressure. The Stark broadening and the Stark shift of the emission lines were used to estimate the ele...

Description
Summary:The intensities, widths, and shifts of the centres of the emission lines of a laser plasma generated on the surfaces of solid targets were determined experimentally as a function of the ambient gas pressure. The Stark broadening and the Stark shift of the emission lines were used to estimate the electron temperature and the electron density at various gas pressures.
