    Abstract: A device for engraving a diffraction grating on a workpiece, comprises an optical set-up comprising alaser, a beam forming device, a beam splitting device, and a focusing head. The laser is configured tooutput a laser beam. The beam forming device is configured to control a diameter of and a lightintensity distribution in the laser beam, and output a primary laser beam. The beam splitting deviceis configured for a splitting of the primary laser beam into a plurality of split beams for theengraving. The focusing head comprises a microscope objective lens (109) configured to focus therespective split beams in respective foci on the workpiece, an auto-focusing system configured toproduce a positioning signal for adjusting and maintaining a distance between the microscopeobjective lens and the workpiece in order to maintain the respective foci of the split beams on theworkpiece and output the positioning signal; and a micro-actuator configured to receive thepositioning signal and adjust the distance between the microscope objective lens and the workpiece,whereby the auto-focusing system and the micro-actuator are operationally connected in a closed-loop. The device for engraving further comprises a positioning device configured to perform arelative positioning between the workpiece in the respective foci of the split beams, and the opticalset-up; and a controller configured to control the positioning device and the laser according toengraving instructions for the diffraction grating.
