In this paper we use a 1-D electromagnetic plasma simulation code to provide a more rigorous study of ionization-induced frequency shifts in subpicosecond laser pulses. The objectives are (1) to calculate the relative contributions of field ionization and electron-impact ionization, (2) to study the effect of Coulomb collisions, (3) to test the validity of the Drude model, and (4) to check the sensitivity of the frequency shift and the spectral broadening to the laser parameters and to the properties of the ionized gas. 9 refs., 8 figs.
