This paper focuses on the precision assembly of laser resonators, which is one of the last and at the same time the most crucial assembly steps in terms of beam quality and laser power. The paper presents an alternative approach for laser resonator alignment consisting of a piezo-based active alignment tool developed for miniaturized laser systems for marking and engraving applications.
