Abstract

The formation of the thermally induced plasma is regulated by the use of cold gas or a cold gas mixture, for example argon and/or helium, and mixtures of these gases with carbon dioxide, oxygen and/or nitrogen, and by choosing the temperature of this gas or gas mixture between room temperature and the boiling point of the gas or gas mixture, preferably from a temperature range from about 0 DEG C to about 120 DEG C, during laser machining of the metal with high power densities. The quality in the laser machining of metal is thus substantially improved in a simple manner.
