POLARIZATION DEPENDENCE OF THE ASYMMETRY IN THE ANGULAR-DISTRIBUTION OF PHOTOELECTRONS EJECTED FROM AN ATOM UNDER THE ACTION OF A BICHROMATIC LASER FIELD

The angular distribution of photoelectrons ejected from atoms under th e action of a coherent mixture of the fields of the fundamental wave a nd the second harmonic is calculated. The case of linearly polarized s econd-harmonic radiation and elliptically polarized fundamental radiat ion is considered. It is demonstrated that the asymmetry in the angula r distribution of photoelectrons is highly sensitive to the parameters of elliptical polarization of the fundamental wave. Along with the me asurement of the phase difference, this effect can be applied to contr ol the angular distribution of photoelectrons.
