Abstract

For many years the C02-Iaser is the most common laser in materials processing. However, in recent years new technologies require lasers which are most suitable for a specific task. In a feasibility study the authors investigated metal processing with Copper vapor lasers. The lasers used had a repetition rate of 7kHz and an output power of 4W and 23W, respectively. It was found that the surface could be modified in a similar manner as it is known from the Excimer laser processing. In the paper the authors present preliminary results of the beam/ substrate interaction and the observed drilling velocity for different substrates. Narrow holes with a diameter to width ratio of about 1:30 could be drilled.
