A system for homogenizing a laser pulse emitted by a laser source in order to illuminate a target homogeneously, the system having, between the laser source and the target: a phase plate constituted by a plurality of subpupils capable of generating a plurality of delayed laser beams towards the target, the path difference &#x394;d between two adjacent delayed laser beams being greater than or equal to the length of the temporal coherence Tof the laser pulse, and focusing device; wherein the subpupils and the focusing device are adjusted so that the delayed laser beams are superimposed on the target in a homogeneous spot.

Homogenizer including a phase plate

A device for amplifying high-energy ultrashort light pulses, includes a generator (), a first amplifying/time-stretching element () including a time-stretching element (), a regenerative amplifier (), a multipass amplifier () and a compressor (). The device further includes a second amplifying/time-stretching element (), arranged at the output of the generator (), amplifying and time-stretching the initial light pulses () to generate amplified and time-stretched pulses (), and a filtering element () arranged between the second amplifying/time-stretching element () and the amplification unit (), blocking the low-amplitude light signals () of the amplified and time-stretched pulses ().
