Ultraviolet-Visible Spectroscopy of Laser-Produced Aluminum Plasmas

Abstract

The optical emission spectra (180 to 760 nm) of plasmas produced by a flashlamp-pumped dye laser focused on an aluminum target have been recorded and analyzed. In the incident intensity range from near plasma threshold to 5 x 107 W/cm2, the electron temperature was calculated from the relative emission intensity of A1(II) states (Te = 8.0 x 103 K). The electron density was determined from Stark broadened linewidths of four Al(II) lines. Both the spatial and temporal dependence of the emission spectra were obtained, providing a map of the electron density and temperature. Keywords: Laser effects, Plasma spectroscopy, Laser produced plasma.
