Using a nonperturbative scattering theory, we study the photoionization of xenon atoms irradiated by a bichromatic laser field of linear and circular polarizations. The bichromatic laser field is modulated in such a way that it comprises an infinite sequence of identical, one-cycle laser pulses. The photoelectron angular distribution (PAD) in such a field is inversion asymmetric and depends on the phase difference between laser modes, the laser polarization and intensity, and the kinetic energy of photoelectrons. By investigating the broadening effect in the PADs of lower-order peaks, we show that one can perform an effective control on the motion of electrons of high kinetic energy.
