In ablation processes, a depth control system utilizing optical coherence tomography can be implemented to improve geometrical accuracy and reduce surface roughness. The actuating variable for the control loop is pulse energy, which in the simplest case involves switching laser pulses on and off along the initial scan path as required. However, every suppressed pulse contributes to a decrease in productivity, which is a critical criterion for industrial applications. For this reason, an approach was taken to deploy the scan path as an additional actuating variable. The developed algorithm is designed for improving the scan path during the process by omitting already finished areas. Theoretical verification with sample geometries shows a significant improvement in productivity compared to bare pulse toggling.
