We report here on high-resolution spectral measurements of Stark-broadened 3[ital d]-5[ital f] lines from lithiumlike ions and 3[ital d]-4[ital f] lines from heliumlike ions. The spectra were emitted from high-density laser-produced plasmas. Plasmas were produced by irradiating thin- and thick-foil targets made of magnesium, aluminum, phosphorus, and chlorine with the OMEGA laser in a line-focus geometry. Line profiles were compared to a Stark-broadening calculation that uses the static-ion approximation and an impact approximation for the electrons. The dependence of Stark broadening on atomic number is discussed. For the aluminum plasmas [similar to]10% narrowing was observed in the width of the 3[ital d]-5[ital f] line as the length of the plasma was increased from 3 to 6 mm.
