Abstract

Satellite lines emitted by a three-level atomic model in the presence of longitudinal electrostatic plasma waves and a non-resonant laser radiation field are investigated by calculating the autocorrelation function of the emitted light wave up to fourth order in the perturbation energy of the atomic system. Both the plasma wave and the radiation fields lead to a shift of the second-order Baranger and Mozer (1961) plasma satellites and of the allowed line. The intensities of the plasma satellites are enhanced by the laser radiation field. Under certain frequency conditions satellites pertaining to the radiation field appear in absorption. The same phenomenon occurs for the plasma satellites when the atoms are subjected to a single-mode plasma wave field.
