Fig. 4.. Low frequency and high frequency periodic surface structures formed on CdZnTe sample at an energy of E = 55 μJ (peak fluence F_p≈7.0 J/cm²) for high pulse number N, namely (a) N = 500 and (b) N = 1000. The corresponding FFT spectra are shown in panels (c, d), while panel (e) displays the profiles taken over the white dotted lines shown in panels (c, d). In panels (c-e) the term LF and HF indicate low and high spatial frequency, respectively.
