Luminescence of Femtosecond Laser-Processed ZnSe Crystal

Figure 1

SEM images of ZnSe laser-treated surface N2 with different magnification (a, b), 2D Fourier transform of a SEM image (a) of ZnSe surface N2 (c), Fourier transform profile along the line at 2D Fourier transform (d), and two kinds of the inverse transform of 2D Fourier transform presented at (c) (e, f). Red circles at 2D Fourier transform images indicate the areas that have been taken for the inverse transform. The inset at (a) presents the process of fs-laser treatment of ZnSe single crystal.
