The influence of Goos–Hänchen shift on total reflection of ultrashort light pulses

The influence of Goos–Hänchen shift on the total reflection of ultrashort light pulses is analyzed. If the incident pulse has an infinite beam width, the reflected pulse keeps the same shape as the incident pulse, but experiences a time delay. If the incident pulse has a spatially limited beam width (the pulsed beam), the reflected pulsed beam undergoes a carrier frequency shift and other distortions that depend on the Goos–Hänchen shift, the magnitude of the beam width, and the duration of the pulse.
