Figure 4
(a) Horizontal (left) and vertical (right) cuts of intensity distributions at the geometrical focal point of the KB system with ∼546 (∼233) horizontal (vertical) demagnification, obtained by the three different calculation methods, as described in the caption to Fig. 2[link], for a coherent Gaussian beam with 10 µm RMS waist size (at the source) and ∼0.822 µrad divergence. (b) Same for the Gaussian beam with 60 µm RMS waist size and ∼0.137 µrad divergence. (c) Image plots of the two-dimensional intensity distributions obtained in (b) using the extended grazing-incidence mirror methods: the wavefront propagation (left) and the geometrical ray-tracing (right).
