	To provide different beam lines with laser light from one source, a fast switching mirror unit that allows permanent switching with a frequency of up to 2.5 Hz was developed. One part of the study deals with the mirror and the design of its mounting in the chamber. The challenge lies in achieving a firm mounting of the mirror without significant mirror deformation, since the users demand only very few divergence of the laser beam at the test sites. The newest design of the mounting brought considerable improvement with regard to the pitching and the torsion of the mirror, which have an important impact on the beam divergence.

To provide different beam lines with laser light from one source, a fast switching mirror unit that allows permanent switching with a frequency of up to 2.5 Hz was developed.
