THz pulse generated by an ion-irradiated photoconductive antenna and detected by a 0.42 mm thick DAST crystal using optical phase detection. Inset: schematic of the experimental setup with the detection block.
Fourier transform of the temporal waveform in Fig. 1.
Magnitude of the time-domain peak and of the total optical intensity incident onto the photodiode as a function of the path difference between the two optical beams of the interferometer.
The ratio between calculated in a DAST using optical phase detection technique and in a GaAs crystal using traditional electro-optic sampling as a function of the THz frequency.
