Problems solved by technology

During operation of the laser, the mechanical and thermal load of the heat sink can lead to clamping (Verspannung) and thus deformation of the laser disc, which can limit the achievable laser power

Embodiment Construction

[0022] The aspects described here are partly based on the recognition that, for example, in the case of a holding type acting on the disc module from the front, for example by means of the three-point clamping mentioned at the outset, it is possible to cause Aspheric deformation of laser disks. It has also been found that the resulting aspheric optical effects can lead to a reclassification of the laser power into undesired modes of the underlying laser resonator. This can lead to an unstable operation of the laser system, in which, for example, despite an increased pump power, a correspondingly high laser power cannot be coupled out or even less laser power is coupled out. It has been recognized that the symmetry in the number of bearing points of three can be reflected in a clamping of the laser disk, which can lead to aspherical deformations of the laser disk and thus possibly to a limitation of the achievable laser power.

[0023] It is generally recognized that the reten...

Abstract

A laser disk carrier system (11) has: a disk module (15) having a circular disk-shaped heat sink (15A), which has a front side (23A), a rear side (23B) and an edge surface (23C) connecting the front side (23A) and the rear side (23B), and having a laser disk (15B) provided on the front side (23A) of the heat sink (15A); and a radial holding device (13) having an opening (25) for receiving the diskmodule (15), the disk module being held in the radial holding device (13) in such a way that force is applied to the edge surface (23C) in a radial direction.

Description

technical field [0001] The invention relates to a disk laser system and in particular to a laser disk carrier for clamping and optimally holding a laser disk module. Background technique [0002] The use of plate-shaped laser active media (hereinafter also referred to as laser disks) in solid-state laser assemblies is known. Exemplary solid-state laser components are known from DE 10 2012 214 970 A1 and EP 1 677 394 A1. The laser disk can in particular be configured in the form of a disk. It is also known to fasten such a laser disk to a heat sink, such as a diamond heat sink, for example by gluing, bonding or soldering, as is known, for example, from EP 1 178 579 A2. Here, the combination of laser disk and heat sink is called disk module and the corresponding laser system is called disk laser. [0003] The disk modules are usually held in so-called cooling fingers for cooling. For example, the disk module can be clamped on the front side of the heat medium via three bea...
