Spatiotemporal Goos–Hänchen effect at a laser pulse reflection from boundary of supercritical plasma

The spatiotemporal Goos–Hänchen effect is considered when s- and p-polarized laser pulses are incident from a vacuum onto the boundary of the supercritical plasma. It is shown that, in addition to the lateral shift, the reflection of a laser pulse from the plasma boundary is also accompanied by its...

Description
Summary:The spatiotemporal Goos–Hänchen effect is considered when s- and p-polarized laser pulses are incident from a vacuum onto the boundary of the supercritical plasma. It is shown that, in addition to the lateral shift, the reflection of a laser pulse from the plasma boundary is also accompanied by its time delay, which can significantly exceed the period of laser oscillations. The dependence of the time delay of the reflected signal on the angle of incidence and polarization of the incident pulse as well as on the density of plasma electrons is studied.
