Storage and subsequent recall of shaped femtosecond waveforms is achieved by performing spectral holography within a femtosecond pulse-shaping apparatus. Readout of the spectral hologram by using a short reference pulse yields both real and time-reversed reconstructions of the original signal. Convolution and correlation operations are achieved by using shaped pulses for readout. These experiments demonstrate the possibility of nonlinear spectral filtering and signal processing of femtosecond optical waveforms.
