In the Rapid-KI project a new process is developed to control laser ablation for repairing or recycling electronic components that are protected by a coating. Therefore experimental data obtained from nanosecond single pulse experiemnts was used to calibrate a simulation model of laser ablation. The expansion of the shock wave was determined using a schlieren imaging system and the Sedov-Taylor theory.
