Abstract :
Summary form only given. We directly compared the measured terahertz radiation taken from free space electro optic sampling (FSEOS) and photoconductive (PC)-sampling. We observed significant difference between the two types of waveforms. We find that the waveforms measured by the PC-antenna can be derived from the FS-EOS waveforms in conjunction with the carrier lifetime of the PC-antenna material and the frequency dependent antenna response.
