Paper Abstract

We present in this paper the characterization of the temporal shape of a picosecond chirped pulse diffracted by a transient grating by four-wave mixing experiments in a bulk sample of polydiacetylenes. We show that the coupled measurements of the amplitude correlation and the spectral intensity allow us to determine, in our simple experimental case, all the parameters for the material and the incident pulse included in the model for the diffracted pulse.
