Abstract: The invention relates to a drilling device comprising a light source configured to provide a light beam and a diffractive beam propagation device having a substantially planar surface, wherein the light source is configured such that the light beam is incident on the planar surface of the diffractive beam propagation device, and wherein the diffractive beam propagation device is configured to propagate the light beam as one or more propagated beams such that the one or more propagated beams, at least when being integrated over time, surround an area with a substantially circular shape. A use of the drilling device for drilling a hole in a work piece and a method suitable for drilling a hole in a work piece are also provided.
