    Abstract: The invention relates to a system for homogenising a laser pulse emitted by a laser source in order to illuminate a target homogeneously. According to the invention, the following elements are disposed between the laser source and the target, namely: a phase plate formed by a plurality of subpupils capable of generating a plurality of delayed laser beams in the direction of the target, the path difference Δd between two adjacent delayed laser beams being greater than the temporal coherence Tc of the laser pulse; and focusing means for superimposing said delayed laser beams on the target in a homogeneous spot.
