Abstract

In contrast to laser cutting and welding, laser drilling is rather unknown for industrial applications today. A main reason for this is the poor processing quantity. In this paper a special Nd:YAG-laser system will be introduced, which is well suited for drilling applications, due to high beam quality as well as high output power. In combination with an acoustooptical Q-switch, high quality drillholes in the micrometers -range have been achieved. Different parameters of the laser process cause variable hole diameter in steel and ceramics. This paper gives some examples, and the advantages and disadvantages of drilling micro holes using a laser are discussed.
