Description
Summary:In the present paper the influence of degenerate four-photon parametric process on the energy exchange between the components of the electrical field for different polarization states of optical pulses is studied. The natural basis for investigating this phenomenon is a system of two coupled nonlinear equations. They govern the interaction between x and y components of laser pulses. A new class analytical solutions, describing the energy exchange between the components of the electric field is presented, where the influence of the effects of self and cross-phase modulation on the energy exchange period is taken into account. The analytical solutions are compared with the numerical calculations.
