Propagation of an Ultrashort Laser Pulse in a Waveguide of Rectangular Cross Section

摘要

The propagation of a spikelike ultrashort laser pulse in a mirror waveguide of rectangular cross section with perfectly conducting walls is considered. An algorithm for the calculation of the propagation of a field pulse in such a waveguide is designed. The general approach is illustrated by calculation of the propagation of a p-polarized field pulse shorter than the dimensions of the waveguide cross section.
