Abstract

The correction of the laser beam aberrations and the formation of the laser beam intensity is very important scientific task. This problem widely is being decided at this moment. The employment of the bimorph deformable mirrors for this kind of applications is very promising. But this type of the wavefront correctors has one reasonable shortcoming – low spatial resolution of the control electrodes, it doesn’t allow to compensate for the high-order wavefront aberrations. This kind of aberrations is valuable for imaging applications, mainly if needs to reconstruct specific details. Therefore, we have to use the wavefront correctors with high spatial resolution of the electrodes. In this work we present two types of the bimorph deformable mirrors for solving this problem – multilayer bimorph (multimorph) mirrors and bimorph mirrors with high density of the control electrodes. To place high number electrodes on the piezodisk the laser engraving technology was used, and ultrasonic welding technology used to make the wire connection to these electrodes. We developed the powerful numerical model to simulate bimorph mirrors.
