A device for projecting a laser beam onto a workpiece includes at least one first optical element, at least one second optical element, and at least one third optical element. The at least one first optical element is configured to project the laser beam onto the at least one second, in particular diffractive, optical element. The at least one second optical element is configured to convert an intensity profile of the laser beam. The at least one third optical element is configured to project the laser beam onto the workpiece. The device is configured such that a diameter of the laser beam on the workpiece can be varied while maintaining the intensity profile with a stationary workpiece.
