Summary/Abstract: In present work the parametric interaction of two optical waves presented by their slowly varying amplitude functions A1(z) and A2(z) in isotropic nonlinear medium is investigated. The corresponding system of nonlinear amplitude differential equations describes the processes of third-harmonic generation and THz generation in femtosecond region. It is found analytical solution of this system, characterizing the periodic exchange of energy between the two waves. The obtained result can be used for investigating different parametric processes in nonlinear dielectric medium, depending on the value of the wavenumber mismatch Dk. These effects are directly related to modern communication systems and optical sensors.
