Beschreibung
Zusammenfassung:	The invention relates to a device for removing material from a workpiece by means of a laser beam, especially a laser drilling device. The inventive device comprises a laser arrangement for producing a laser beam which consists of at least one laser pulse that is characterised by parameter values such as pulse duration and laser wavelength for instance. The aim of the invention is to improve such a device with regard to progress and accuracy of removal. The laser arrangement is configured in such a way that it produces at least two types of laser pulses which differ in at least one parameter value.
