Key Points

  • This research aims to explore free-space electro-optic sampling for characterizing terahertz beams with high temporal resolution.
  • Utilized the linear electro-optic effect for terahertz beam characterization
  • Achieved subpicosecond temporal resolution
  • Implemented cross-correlation with optical pulses for signal processing.
  • Demonstrated a flat frequency response over an ultrawide bandwidth
  • Achieved significant improvement in temporal resolution compared to traditional methods.
  • Enabled simple and effective characterization of freely propagating terahertz beams.

Abstract

Free-space electro-optic sampling is an alternative method for the characterization of freely propagating terahertz beams with subpicosecond temporal resolution. In contrast to resonant photoconductive dipole antennas, free-space electro-optic sampling via the linear electro-optic effect (Pockels effect) offers a flat frequency response over an ultrawide bandwidth and the potential for a simple cross-correlation signal of the terahertz and optical pulses.
