WebbThe system is based on coherent generation and detection of ultra-short THz transients [20]. The detection scheme is based on electro-optic sampling of the electric field of the transients within a 1-mm-thick, (110)-oriented ZnTe crystal as a sensor. This allowed us to measure time profiles of the THz transients transmitted through studied samples.
