Temporal dependence of the diffracted pulse reflectivity Rh t at a fixed observation point inside the crystal. Si(220) reflection; = 0.71 Å; = 0.2 fs; a = 10. The coordinates of the fixed observation points are (a) (-a,1.5), (b) (0,1.5) and (c) (a,1.5). Dashed curve: linear diffraction; solid curve: nonlinear diffraction. Intensity of the incident pulse Ii = 0.5. Numerical calculation. |
