Abstract (en)

[origin: WO2006021298A1] The invention relates to a diode laser containing an optical device (10) which is used to increase the beam density of an output laser beam (12) which is emitted by said laser to the place of an object (16), said laser being made of a plurality of partial beams (8<SUP>(1)</SUP>, 8<SUP>(2)</SUP>, ... 8<SUP>(n)</SUP>) which are produced by a plurality of diode laser elements (2<SUP>(1)</SUP>, 2<SUP>(2)</SUP>, ... 2<SUP>(n)</SUP>). The optical device (10) is arranged downstream from the diode laser elements (2<SUP>(1)</SUP>, 2<SUP>(2)</SUP>, ... 2<SUP>(n)</SUP>) and contains a first Bragg grating volume (18) which only reflects a spectral region (?<SUB>B</SUB> <SUP>(1)</sup
