Claim 2:
3. The laser system according to claim 1, wherein the repetition frequency multiplier device comprises a second optical delay line and an optical combiner having a first output, the second optical delay line being disposed between the second optical coupler-splitter and the optical combiner on a trajectory of the second pulse beam, the second optical delay line being configured to induce an optical delay equal to a quarter of period of the first repetition frequency on the second recombined beam and to generate a second pulse beam delayed by a quarter of period, the optical combiner being configured to recombine the first recombined beam and the second pulse beam, delayed by a quarter of period, and to form on the first output of the optical combiner a first quadruple-repetition frequency beam comprising pulses at a third repetition frequency equal to the quadruple of the first repetition frequency.
