  • Patent number: 9690107
    Abstract: A device for wavelength coupling of laser beams (2a, . . . 2n) with different wavelengths (?1, . . . ?n), comprising: at least one laser source for generating a plurality of laser beams (2a, . . . , 2n), and an overlapping device for spatial overlapping of the plurality of laser beams (2a, . . . , 2n) for forming an overlapped laser beam with a plurality of wavelengths (?1 . . . ?n). The device has a feedback device arranged between the laser source and the overlapping device for feeding a radiation proportion of the laser beams (2a, . . . , 2n) to be overlapped back to the laser source, the feedback device comprising a partially reflecting angle-dispersive optical element, in particular a partially reflecting diffraction grating. The overlapping device may, for example, be configured as a transmitting or reflecting diffraction grating whose optical properties are adapted to the optical properties of the partially reflecting diffraction grating to overlap the laser beams (2a, . . .

  • Patent number: 8345724
    Abstract: A laser system includes a first source and a second source for generating a first laser beam and a second laser beam, respectively, and a mirror arrangement including a first interleaving laser mirror with a high reflecting area configured to reflect the first laser beam and a first high transmitting area configured to transmit the second laser beam.

  • Patent number: 7936799
    Abstract: A laser system includes at least two sources configured to provide at least two spatially separated laser beams, and a mount configured to mount the at least two sources along an arc, the arc defining an angular coordinate and a radial coordinate, wherein an axial coordinate is orthogonal to the angular coordinate and the radial coordinate, and the spatially separated laser beams are separated in the axial coordinate. The mount is further configured to mount the at least two sources providing thereby an offset of the laser beams in the axial coordinate such that the laser beams interleave in the axial direction at a center region of the arc.
