Figure 11
The double-diffracted beam intensity distribution on the focusing plane in a RDL with a silicon lens. Shown are the cases corresponding to = 0 (a), = 1.5 × 10-4 (b), = −1.9 × 10-4 (c). The beam falls at the Bragg-corrected angle corresponding to the wave with = 0. Absorption in the lens is taken into account. Numerical integration by formula (79). Point source. |
