Circular dichroism from unpolarized atoms in multiphoton multicolor ionization

The angular distribution of the photoelectrons produced from a ground-state atom ionized under the combined action of two (or several) radiation fields can exhibit circular dichroism effects, when reversing the polarization state (right versus left, for instance) of one of the fields. We address the question of such dichroic effects in a currently explored scenario in which the atom is ionized in the presence of a strong laser field and of one (or several) of its higher harmonics.
