Figure 5
Numerically calculated rocking curves Rh(yr) [formula (43)] on deviation parameter yr for various values of the intensity of the incidence wave I (i) = 0.1–0.7 with step 0.1 (curves 3–9, respectively) according to nonlinear theory (the width of the beam is 5 linear extinction lengths). The rocking curve of linear theory (numerical calculation) for a beam of the same width (curve 2) and the rocking curve according to standard plane wave linear dynamical diffraction theory (curve 1) are shown as well. Absorbing crystal. |
