The process of the photon echo generation by two non-collinear laser pulses in dye-doped polymer films is investigated theoretically and numerically. When the angle between the wave vectors of excitation pulses is increased, the spectral switch of echo signal frequency is possible. The criterion of the red frequency shift has been obtained.
