ABSTRACT:
A device for shaping objects by removal of material from the surface thereof with a pulsed laser beam and a deflecting device through which the laser bean is guided over the surface of the object. An optical device is provided for changing the distribution of the radiation intensity inside the laser beam cross section. After the passage of the laser beam through this optical device, the radiation intensity has a bell-shaped or Gaussian distribution, or a distribution similar to a bell-shaped or Gaussian distribution, in at least one cross-sectional direction through the laser beam.
