Temporal dependence of the diffracted pulse reflectivity Rh t inside the crystal at a fixed point. Si(220) reflection; = 0.71 Å; = 0.2 fs; a = 1; coordinate of the fixed point (0,1.5). Dashed curve: linear diffraction; solid curve: nonlinear diffraction. Intensity of incident pulse Ii = 0.5. Numerical calculation. |
