Property of a reflected Gaussian pulse beam

摘要

It is theoretically discussed the reflective property of a Gaussian pulse on the planar dielectric interface. When the decoupling and full-interference approximations are considered, the axes of reflected pulse beam undergoes a lateral shift from the position predicted by geometrical optics. At the same time, the reflected pulse beam still emerge the time delay comparing to the incident pulse beam. The reflected profile is different from the incident pulse beam. Both spatial distribution and temporal distribution of the reflected pulse beam come out the aberrance.
