Chaotic Dynamics of a Nonlinear Ring Cavity Driven by an External   Multi-frequency Signal
  Complex dynamics of a ring cavity filled by the medium with cubic phase non-linearity driven by an external multi-frequency signal is studied. To describe the dynamics of envelope amplitudes the system of coupled Ikeda maps was derived. The results of numerical simulations in the case of two-frequency external signal are presented. Complex dynamics observed in these numerical simulations is expected to be peculiar for other physical systems that can be treated as nonlinear resonators driven by an external force.
