摘要：

We report femtosecond optical signal processing by using second-order spectral holography. Enhanced second-order diffraction from a thermoplastic plate makes possible new signal-processing operations not possible with first-order holography. Experiments resulting in output waveforms equal to the autoconvolution function of the input waveform are described, and the possibility of implementing a simple associative memory for ultrafast optical signals is discussed.
