On the Method of Multi-Layer Laser Micro Machining

WITKOWSKI Grzegorz

Abstract. The presented method was developed for laser micromachining of material surfaces. The method allows to the creation of a spatial structure (2.5D) with the usage of a laser beam. The method presented in the article should be classified as removal techniques using the phenomenon of cold ablation. The method can be successfully used for pico- and femtosecond lasers equipped with a galvo scanning head. The advantage of the method is that it generates trajectories and modulates beam power based on the spatial geometry of the structure contained in the 3D data exchange file. The method uses proprietary solutions allowing for proper modulation of the laser beam power depending on the required geometry. The control application for the laser device and galvo head was developed based on the National Instruments LabView environment.
