Abstract

We investigate experimentally and numerically the properties of single-cycle terahertz pulses propagating through a focus. The experimental data clearly show changes in pulse shape resulting from the Gouy phase shift and apparent superluminal pulse propagation. The pulses are also considerably distorted by diffraction effects. A solution of the time-domain diffraction integral is necessary to explain the details of the data and leads to an excellent agreement between experiment and theory.

  13. The ripples after the main pulse at z=0 in the time-domain data and the dips in the spectra at z=0 may arise from interference with scattered light. This possibility is included in the simulations by addition of a small contribution of background light treated as a plane wave. Without this additional contribution, the simulated data show no ripples or dips.
