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.
