A versatile laser trepanning system has been designed and implemented, enabling the adjustment of beam displacement and inclination during the fast rotation of the optics. The presented trepanning systems drill differently tapered through-holes with a diameter in a range of 50 to 1500 µm. The novel trepanning systems have been customized for different applications, ranging from basic research quest to industrial production. This paper outlines the development steps and advanced performance, accenting laser micro machining of up to 1 mm thick metal and ceramic samples and laser parameters, realizing differently tapered through holes with an entrance diameter in the range of 65 to 1000 µm.
