ABSTRACT:
A piezoceramic servo-drive for producing translational and angular moveme especially for application to ring laser mirrors, and including piezo discs arranged in a column. The discs are polarised in such a way that the direction of extension of the column and the direction of the electrical field lie in parallel. The discs are provided on one side with a complete contact surface and on the other side are divided into electrically separate contact segments which are provided with separate electrical connections.
