Notes:
This work is focused on laser modification of polymers with different angles ofincidence. Periodic surface structures generated by linearly polarized F2 laser light (157 nm) onpolyethyleneterephthalate (PET) were studied. Atomic force microscopy was used to study thetopological changes induced by the laser irradiation. The laser irradiation induces the formation ofperiodic ripple structures, the width of and the height being angle dependent. The periodic structureswere formed with the laser fluence 4.70 mJ/cm2. The laser modified PET foils were coated with a50 nm thick gold layer by sputtering. After Au deposition on the laser PET foils with ripplestructure, the roughness of surface decreases in comparison to PET with ripples without Au coating
