Stark line broadening of the n=4 to 3 transitions of He-like Ne, Mg, and Al in multicharged ion plasmas is considered. Line profiles calculations involved quasi-static ion broadening, impact electron broadening, natural, and Doppler broadening. Considerable effect of Stark line broadening due to plasma ions for the 4F-3D transitions of He-like Ne is demonstrated at the Ne-plasma parameters yielding a maximum gain in the theoretical modeling of the resonantly photopumped Na-Ne x-ray laser scheme under the conditions of the Saturn experiments. The sensitivity of the calculated line profiles to the intermediate coupling effects and different energy level data is also investigated. Calculated line profiles of the 4F-3D transitions in He-like Mg and Al are compared to the experimental and other theoretical data.
