a. Sketch of the THz time ___domain spectrometer. In the inset, the photograph of the tunable cryogenic cavity composed of two cryo-cooled moving mirrors within which the sample is embedded. b. Free-space nearly single-cycle THz field employed in the experiments detected trough Electro-Optical Sampling (EOS) in a 0.5âmm ZnTe crystal. c. Fourier transform of the nearly single-cycle THz field in free space. In the inset, the Fourier spectrum is plotted in logarithmic scale to highlight the spectral content of the THz field up to ⌠6âTHz. The black dashed line in the logarithmic plot indicates the noise level.
