Abstract
The invention relates to a device for influencing a laser beam by means of an adaptive mirror ( ) in the beam path, having a piezoelectric adjusting member ( ) arranged on the back of the mirror ( ), it being the case that, in order to achieve low-aberration deformation of the mirror ( ) for the purpose of influencing the divergence of the beam, there is provided between the adjusting member ( ) and the back ( ) of the mirror ( ) a pressure-transmitting device ( ) which acts on a large area of the deformable surface of the mirror ( ).
