Abstract

The overview of all laser marking processes for a wide range of materials shows the versatile aspect of laser technology. The statement that all materials can be written by laser is temping but not correct. The writing of liquids and gasses is possible but not practical. The overview of processes for laser marking is therefore a practical guide for the use of laser marking. Flexibility and a readable contrast are the key items for the application of laser marking. The low thermal conductivity and high transparency of polymers makes the laser the best tool to get energy into a volume of a polymer. By using different wavelengths this absorption is selective. This enables selective bleaching of pigments for full colour laser marking.
