This paper shows the results of calculations, obtained by computer simulation, of the Stark broadening of the dipolar Lyman line of hydrogen considering fine structure, of two–photon absorption profiles for the transition 1S2S of hydrogen and of the profiles that could be obtained using two–photon polarization spectroscopy techniques for the aforementioned transition. Calculations have been carried forward for wide ranges of electron density, between 4 1019 and 1023 m-3 and temperature, between 2 000 and 100 000 K. We have considered ion dynamics effects with perturbers of different masses. In this paper we give the obtained profiles and the autocorrelation functions. These autocorrelation functions could be used in order to add another broadening mechanisms before obtaining the spectral profiles.
