English, We study theoretically and experimentally the synthesis of arbitrary time-domain pulse shapes, using short laser pulses scattered by holograms stored in a spectrally selective hole-burning material. in general, writing holograms in spectrally selective materials results in cross talk and interference between different frequencies because of Kramers-Kronig dispersion relations. We discuss different ways to exclude the cross talk that disturbs faithful reproduction of the desired time-domain pulse shapes. In particular, we show that one can exclude the cross talk by writing holograms in a way that simulates a time-domain offset of the object pulse. To confirm our theoretical considerations we carry out experiments by writing persistent spectral hole-burning holograms with a tunable dye laser in an organic dye-polymer system at low temperature. By reading out the time-domain response with subpicosecond white-light pulses we demonstrate the feasibility of spectral synthesis of light pulses with complicated amplitude and phase properties on the time scale of hundreds of picoseconds with a subpicosecond time resolution.
