An adaptive mirror that includes a substrate layer, on the first surface of which a reflecting layer and on the second surface of which at least one actuator is disposed. The substrate layer has a thickness of less than or equal to 1,000 &#x3bc;m and the mirror having at least one further metallization for thermal compensation, as a result of which a thermal deformation of the mirror is avoided or preadjusted such that the desired curvature is set as a function of the reflected power.

Adaptive deformable mirror for compensation of defects of a wavefront

The invention relates to an adaptive mirror based on a ceramic substrate having a corresponding reflector and piezoelectric actuators, a cooling device being integrated in the substrate. The invention likewise relates to a method for the production of such mirrors. The mirrors according to the invention are used for the modulation or deformation of a laser wavefront of high power.
