Abstract: This work investigates the possibility of ablatingpaint from aerospace material with a XeCl- laser. Themain advantage of this type of laser is the low heatgeneration during the ablation process. This isimportant when stripping thermally sensitive materialssuch as polymer composites. The dependence of theablation process on energy density, pulse frequency aswell as other laser parameters are presented. Theresults show the influence of chemical and UVartificial aging processes on ablation depth. Further,the behavior of the time-averaged transmission of thelaser beam through the plasma is described as afunction of the energy density. The time-varyingtemperature in the substrate at the point of ablationwas measured during the process. An abrupt change inthe temperature variation indicates the end of pointablation. This measured temperature variation iscompared with the calculated temperatures, which arederived from the 1D heat equations. Finally, firstresults of repaintability and ablation rates will bepresented.!3
