This work is devoted to the study of the high-order harmonic generation (HHG) induced by two component field with mutually orthogonal polarization of low-frequency and high-frequency components. A new method for separation of HHG channels induced by low-frequency and high-frequency fields based on polarization measurements is proposed. The influence of the initial state symmetry on the efficiency of channel separation is discussed. Keywords: high-order harmonic generation, two-component laser field, ultrashort laser pulses, attosecond pulses, XUV-initiated processes, polarization filtering.
