Title: Method for cutting materials using a laser beam

Abstract: This invention relates to a method for cutting materials using a laser beam, which emerges from a cutting head comprising a cutting nozzle with an inner edge, and is absorbed by the cutting front. The axis of the laser beam is displaced in relation to a workpiece along a cutting line with a fixed orientation in the cutting direction of said workpiece. In this method the position (p) of the cutting head is modulated with regard to its time averaged value, or the laser power and gas pressure in the cutting head are modulated.
