  Using the generalized perturbation reduction method the Hirota equation is
transformed to the coupled nonlinear Schr\"odinger equations for auxiliary
functions. A solution in the form of a two-component vector nonlinear pulse is
obtained. The components of the pulse oscillate with the sum and difference of
the frequencies and the wave numbers. Explicit analytical expressions for the
shape and parameters of the two-component nonlinear pulse are presented.
