Comparison of terahertz waveforms measured by electro-optic and photoconductive sampling

This is the authors' abstract. We don't add key points for this paper.

Terahertz waveforms measured by free-space electro-optic sampling and a photoconductive dipole antenna were carefully compared. We show that the difference between the waveforms could be explained quantitatively in terms of carrier lifetime and frequency dependent response of the photoconductive receiver antenna.
