Fractal parameters vs. AFM scanning area of the layer for “lakes”: (a) a number of “lakes” vs. fractal area size; (b) fractal dimension vs. different fractal area size for two AFM scan areas 1 μm × 1 μm and 2 μm × 2 μm for 200 laser pulses. While the fractal parameters diverging with the scanning area, as expected, the trend of the variation of fractal parameters for different scanning areas remain the same.
