Abstract
Devices and methods for processing a workpiece along a predetermined processing line are provided. The device includes: a pulsed, polychromatic laser beam generator; an optical arrangement; and a moving device. The laser beam generator generates a laser beam along a beam direction. The optical arrangement generates a focal line along the beam direction. The optical arrangement has a chromatic aberration for wavelength-dependent focusing of the laser beam and a filter for wavelength-dependent filtering of the laser beam. The moving device generates relative movement between the laser beam and the workpiece along the predetermined processing line.
