Abstract

Necessity of miniaturize and to create reliable components for wavefront correctors leads to reduction of the cross-section of the control elements in deformable mirrors. Moreover, such elements should provide reasonable stroke to compensate for wavefront aberrations of the laser radiation propagated through turbulent atmosphere. In this work we simulated the possibility of reducing the cross-sectional area of piezoactuators from 16 mm2 to 5 mm2 in order to hold up the local stroke as 5 microns in the cartridge-type deformable mirror for correction of large- and small-scale phase fluctuations of laser radiation. To increase the reliability of deformable mirror design, the gap structure was used for wiring of electrodes instead of interdigitated commutation.
