摘要： This disclosure relates to pumping light systems and methods for using a disc laser. A focusing device with a reflecting surface focuses a pumping light beam onto a laser-active medium. A deflecting system deflects the pumping light beam between reflecting regions formed on the reflecting surface that are arranged in different angle regions around a central axis of the reflecting surface in at least a first annular region and a second annular region. The deflecting systems are configured to perform at least one deflection of the pumping light beam between two reflecting regions of the first annular region and at least one deflection between two reflecting regions of the second annular region.

摘要： Wavelength-selective external resonators can be used to greatly increase the output brightness of dense wavelength beam combining (DWBC) system beams by stabilizing the wavelengths of the beams emitted by the individual emitters of the DWBC laser source. The present invention pertains to external resonant cavities that utilize thin-film filtering elements as wavelength-selective elements in external resonators. The present invention further pertains to particular embodiments that utilize thin-film filtering elements in DWBC systems as both output beam coupling elements and wavelength selective elements. The present invention provides advantages over the prior art that include decreased cost, increased fidelity of wavelength selection, and increased wall plug efficiency.

摘要： A scanner device configured for 2-dimensional deflection of a laser beam by mirrors that are each pivotably supported about an axis and that are driven in a motorized manner, includes a first motor-mirror unit that has a first mirror and a drive motor, and a carrier for securing the first motor-mirror unit. The first motor-mirror unit is selected from one of two different possible motor-mirror units, each of which has an assembly flange, an identical abutment face, and can be selectively releasably secured with the abutment faces to the same first assembly face of the carrier. The two different possible motor-mirror units differ from each other with respect to the mirror size and/or mirror position in the carrier.

摘要： The disclosure relates to a pump radiation arrangement comprising: a pump radiation source for producing pump radiation, a means for stabilizing the wavelength of the pump radiation source and a laser-active medium through which the pump radiation passes in a bidirectional manner. The pump radiation arrangement also has a retro-reflector for reflecting pump radiation which is not absorbed by the laser-active medium back to the pump radiation source and a wavelength-selective element for preventing a wavelength destabilization of the pump radiation source by filtering out undesirable spectral portions of pump radiation which is not absorbed by the laser-active medium. The invention also relates to an associated method for pumping a laser-active medium.
