In a beam propagating through a dispersive prism a delay of the pulse front occurs. A general expression relating the delay and the angular dispersion was found. Using a streak camera this delay was experimentally observed. In practical systems the delay varies from a few to several tens of picoseconds. A pulse compressor equivalent to the Treacy-compressor, based on this delay is described. A novel scheme for the excitation of a travelling-wave picosecond amplified spontaneous emission is also proposed.
