Figure 8
The focal spot (a) and its cross section (b) when using a coherent Gaussian source with an opening angle of 12.4 µrad for ideal mirrors and for mirrors with figure errors (c, d). The intensity plots were normalized so as to contain the same energy as the coherent source for the ideal mirrors case. By comparison the aberrated mirrors results in a maximum amplitude of 0.992 if for the ideal mirrors amplitude is normalized to reach unity.
