Abstract

The invention relates to a laser machining device (100) for drilling holes into a workpiece, particularly into an electronic circuit substrate (150), which comprises: a laser source (110) provided for emitting a laser beam (111); a diverting unit (130) for directing the laser beam (121) to a defined drilling position (154) on the circuit substrate (150), and; a projection lens (140) for focussing the laser beam (141) on the circuit substrate (150). The laser machining device also comprises an optical deflecting device (120), which is situated between the laser source and the diverting unit, serves to carry out the periodic two-dimensional diversion of a laser beam, and which has an optical element and a rotary actuator. The optical element is mounted in a manner that enables it to rotate about a rotation axis and has a planar boundary surface whose normal to the surface is oriented at an angle to the rotation axis and which is such that, when a laser beam impinges thereupon, it deflects this laser beam from its original direction. The rotary actuator is designed for continuously rotating the optical element about the rotation axis.
