We studied the profile of the hydrogenic Ly-alpha line under the two-dimensional multimode quasimonochromatic electric field. We obtained the Stark profile of the main line and of the satellites in the form of the onefold integral. We demonstrated analytically and by numerical calculations that the Stark profile of the main line and of its satellites has a cusp in its center. This unusual shape of the Stark profile is a counterintuitive result.
