Figure 4
Two-dimensional distribution of amplitude of the reflected pulse |Ah(xp, zp)| in the symmetric Laue case (b = 1). Distance from the crystal to the pulse R = 2 cm (a), and R = 10 cm (b). Duration of incident pulse τ0 = 1 fs, crystal thickness d = 23.19 µm, critical distance RD = 8.2 cm, angle of pulse inclination φh = −41.2°. For the incident pulse of longitudinal size l0 = 0.3 µm there appears to be a δ-function on the background of the spatial distribution of the reflected pulse and consequently it is not shown in these figures. Other parameters: size of source rs = 75 µm, phase parameter αs = 2, distance from source to crystal zs = 800 m, transversal size of incident pulse r0 = 1240 µm, phase parameter α0 = 36.9. |
