The generation of an exact time-reversed complex amplitude ultrafast waveforms are described using a wave mixing process based on second-order nonlinearities for a four-wave interaction. As with spectral holography, the wave mixing is performed with spectrally decomposed waves (SDW). The resultant intermediate wave amplitude is proportional to the product of the complex U1 and U2 amplitudes. The second nonlinearity is a frequency difference process that mixes the intermediated with the SAW of the second reference pulse. The inversion is due to the opposite directions of the spatial dispersion from the gratings, corresponding to the +1 and -1 diffraction orders.
