The invention relates to a device for generating a plurality of laser beams. The device comprises:a laser source emitting an initial beam at P wavelengths;a wavelength splitter assembly for splitting the initial beam into N intermediate beams where N<=P, each intermediate beam containing a group of wavelengths comprising at least one wavelength; andN' energy splitter assemblies where N'<=N for splitting an intermediate beam into ni divisional beams, each of the ni divisional beams having substantially the same energy, whereby K divisional beams are obtained with
