Figure 4
Linearly polarized incident radiation (single short pulse). Shown is the reflected amplitude in the σπ plane and its mirror image, to visualize the polarization plane. With time (shown as a third axis perpendicular to the σπ plane) the polarization plane begins to rotate. At 21 fs the polarization is perpendicular to the plane of incidence, whereas at 32 fs it is parallel to the plane of incidence, and so on. |
