Abstract

A deformable mirror, especially for the compensation of the influences of atmospheric interferences on the propagation or spreading of high energy laser beams, which incorporates a plurality of electrically actuatable actuators or adjusting elements engaging behind the mirror surface of the mirror. The actuators or adjusting elements is pressed against the rear side of a mirror plate, and is connected therewith along jacket or sheathing surfaces. Thereby, it is possible to achieve an almost point-like introduction of force for the regional deformation of the mirror; inasmuch as the pressure forces can act with a practically randomly small cross-section directly against the rear side of the mirror, while the tensile forces are taken up by the jacket or sheathing surfaces.
