Abstract: This disclosure relates to laser disk mounting systems and methods. The laser disk mounting systems comprise a disk module with a round disk-shaped heat sink having a front side, a rear side, and an edge surface connecting the front side and the rear side, and a laser disk arranged on the front side of the heat sink, and a radial mounting device with an opening for receiving the disk module, wherein the disk module is mounted in the radial mounting device such that a force action is applied in radial direction on the edge surface.

Abstract: Beam adaptation devices are disclosed for variable-astigmatic adjustment of electromagnetic radiation propagating along a beam axis of the beam adaptation device. The devices include a first astigmatism lens unit, which provides at least one first lens tiltable with respect to the beam axis for astigmatism adjustment, a divergence matching lens unit with a second lens for adjusting the divergence, wherein the distance between the second lens and the first lens along the beam axis is adjustable, and a second astigmatism lens unit with at least one third lens tiltable with respect to the beam axis for astigmatism adjustment. To adjust the magnitude of the electromagnetic radiation on the third lens, the distance between the second lens and the third lens along the beam axis is adjustable. The beam adaptation device can be used, for example, for astigmatic pre-compensation in frequency conversion.
