The results of experimental study of the dependence of the light efficiency of the First and Second Positive Systems of nitrogen lines (FPS and SPS) on the parameters of the acoustoplasmic discharge are presented. The spectral regions FPS (575 - 687nm) and SPS (350 - 435nm) are considered. The working mixture of CO2 laser (CO2:N2:He=1:1:8) was investigated. It is noted that the main portion of the energy in the visible spectrum for such a mixture is concentrated in FPS and SPS nitrogen lines. The data on the selective strengthening of individual spectral lines of nitrogen, depending on the discharge parameters, are presented. Pressures in the region from 0.1 to 50 torr were investigated. The DC discharge is compared with acoustoplasma discharge. The change in the intensity of the strong red line (about 655 nm) from the modulation frequency of the discharge current in the acoustoplasmic mode is given. It has a resonant character and can be changed almost 5 or more times. The shift of the strong red spectral line in pure nitrogen plasma relative to tabular spectral lines was found.
