AFM, FFT and 3D images of sample 1 with d=493 nm. a By placing a lens with f=12.5 mm with the surface of sample in focal point, interference pattern caused by the lens is visible on the surface. This confirms the dependency on light intensity for structuring. This sample was irradiated for 30 min with linear polarization. b Here, the situation is the same as in a) with the lens, but with CPL
