Abstract

The device for deflecting a laser beam comprises a mirror (1) and means for orientating the mirror according to a predetermined equation for the controlled deflection of the laser beam (F). The mirror (1) is supported so that it can oscillate about two axes and the means for orientating the mirror comprise a plurality of electromagnets (11A, 11B, 15; 13A, 13B, 17) supplied with currents which are controlled and variable in time (I15, I17) to exert magnetic forces on said mirror (3).
