Copper is very difficult mark, but by setting the waveforms it can be marked by even a few shades with very high contrast. There is a very high demand for this type of processing from customers who are looking for new methods of processing and identification of products.
There is a challenging type of processing – materials with high reflectivity, hence it is necessary to achieve high peak power to ensure that there will be a sufficient amount of radiation absorbed by the material. When using a process with more waveforms, the first pass uses high peak performance and the energy in the pulse to create a base for the second pass. The second pass then uses a different length of the pulse, scanning speed and frequency, creating characters on the surface of the piece.
