The surface roughness and the optical properties of dense polytetrafluoroethylene (PTFE) can be modified by 157 -laser irradiation in atmosphere. With PTFE foils, laser-treatment results in an improved transparency which is attributed to a smoothening of the surface. The treated foils exhibit a similar mechanical stability as the untreated ones.
