Method for Controlling a Laser Source, in Particular a Pulsed Laser Source, for Cutting, Engraving, Marking and/or Labeling a Workpiece, and Laser Plotter therefor

Abstract

A laser plotter and a method for controlling a laser source for cutting, engraving, marking, and/or labeling a workpiece is disclosed. In a housing of a laser device, at least one laser source is used to process a workpiece, which is preferably placed on a processing table. The workpiece is processed line by line by moving a focusing unit or laser head. Based on the set parameters and/or a loaded job, a control unit generates a frequency signal to control the laser source. At the beginning of the processing operation, the control unit calculates a number of laser pulses for a pixel/path unit. From this, a modulation signal is generated that enables the laser source to emit laser pulses at the constant pulse repetition rate. This signal is applied to the laser source, and the number of laser pulses is kept constant across further pixels/path units.
