SPECTRAL-TEMPORAL EVOLUTION OF THE ELECTRICAL FIELD OF TERAHERTZ PULSE BY FRAUNHOFER SLIT DIFFRACTION
Read the full article ';
Time dependencies of the electric field amplitude for terahertz electromagnetic pulse of a few oscillations for various angles of slit diffraction in the far field are theoretically and experimentally obtained. Significant changes in a temporary form of the electric field of pulse with the increasing of diffraction angle have been revealed, as well as corresponding changes in the spectrum. Comparison of the findings shows a good agreement of calculations and experimental results. Obtained outcomes can be used in pulse terahertz optics and spectroscopy.
