Abstract: An optical arrangement includes a disk-shaped laser-active medium configured to create an optical gain upon being pumped within a pump volume, and a laser beam incoupler for input coupling a laser beam as a seed laser beam into the laser-active medium. The laser beam interacts with the laser-active medium. The optical arrangement further includes an auxiliary resonator for creating an auxiliary resonator radiation field. The auxiliary resonator radiation field interacts with the laser-active medium. The auxiliary resonator is configured to suppress at least one mode of the auxiliary resonator radiation field that overlaps with at least one mode of the laser beam in the pump volume.

Abstract: A device for wavelength coupling of laser beams (2a, . . . 2n) with different wavelengths (λ1, . . . λn), 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 (λ1 . . . λn). 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, . . . , 2n) in an essentially dispersion-free manner.

Abstract: The present disclosure describes systems and methods for beam wavelength stabilization and output beam combining in dense wavelength multiplexing (DWM) systems. Systems and methods are described for performing beam wavelength stabilization and output beam combining in DWM systems while achieving increased wall-plug efficiency and enhanced beam quality. Interferometric external resonator configurations can be used to greatly increase the brightness of DWM system output beams by stabilizing the wavelengths of the beams emitted by the emitters of the DWM laser source. The resonant cavities described by the present disclosure provide advantages over the prior art in the form of decreased cost, increased wall plug efficiency and increased output beam quality. Particular implementations of the disclosure achieve increased wall plug efficiency and increased output beam quality through a combination of innovative cavity designs and the utilization of reflection diffraction elements for beam combining.

Abstract: Disclosed are optical arrangements including: a disk-shaped laser-active medium, a deflecting device, having a plurality of mirror elements on which mirror faces for deflecting a laser beam are formed, and having a base body on which the mirror elements are fastened, the mirror faces of the mirror elements being oriented in such a way that the laser beam is deflected by a respective mirror face via the disk-shaped laser-active medium to another mirror face. The mirror elements are formed in one piece or are monolithically joined, and have a connecting section that is formed rotationally symmetrically with respect to a center axis and is rigidly connected by a material-fit connection or a direct connection to the base body.

Abstract: A fiber amplification system is provided for amplifying a laser pulse signal, e.g., an oscillator signal of an oscillator device. The fiber amplification system includes a fiber pre-amplification system having a short, fundamental-mode and step-index fiber configured to pre-amplify the laser pule signal to generate a seed signal and a main amplification system having a large core fiber configured to amplify the seed signal. The short, fundamental-mode step-index fiber can have a length no longer than about 30 cm, and a mode field diameter no less than about 30 μm, e.g., in a range from 30 μm to 60 μm, as well as a high doping concentration needed to provide an absorption length no more than about 30 cm, for providing the seed signal for the large core fiber with low non-linearity.
