Abstract

An analytical study of THz-waves' intensity measurement generated by Terahertz Parametric Oscillator (TPO) and detection of the THz pulses occurs via free-space electro optic detection by ZnTe crystal has been studied. The pump-probe technique has been used to observe the dynamics of an optically excited ZnTe electro-optic crystal. THz wave will be used as modulation source for electro-optical phenomena in ZnTe crystal. The THz pulses generated by TPO are 10-25 ns pulses at a repetition rate of 1Hz. ZnTe crystal is being used for intensity measurement of THz-waves. In this theoretical proposed experiment, a short pump pulse (THz-wave) and probe pulse (near IR laser) with duration of typically 10 to 25 ns interacts in the ZnTe. In electro-optic sampling the two effects namely Pockels effect and Kerr effect have been discussed and interaction of two beams from or transmission through the ZnTe, the probe pulse Intensity contains information about the THz-waves' intensity and so on.
