Figure 2
Intensity response of Bragg crystals (diamond 111) of different thickness versus time. The units of the abscissa are femtoseconds, whereas the ordinate is in arbitrary units. The crystal thickness for the first curve is T = 0.1 µm and the thickness increases by 0.75 µm from curve to curve. Note that the curves are shifted by 0.1 arbitrary units in the vertical direction with respect to their neighbours for clarity (see text). |
