Webb14 mars 2024 · In our approach, THz radiation arises from the strong plasma current generated when two laser pulses collide with each other on a plasma sheet. During the … WebbWhen a THz pulse technique is used, this type of spectroscopy receives the name of terahertz time domain spectroscopy (THz-TDS). Samples for terahertz spectroscopy need to be compressed prior to spectra acquisition. Samples could be mixed with a diluent (typically polyethylene and polytetrafluoroethylene) and further compressed.
WebbAbstract: We have applied the terahertz (THz) time-domain spectroscopy (TDS) to revealing the mechanism of the relativistic Doppler reflection of the THz light from a photo-induced plasma layer in a silicon wafer. The velocity of moving plasma layer is estimated by the reflected THz waveforms as a function of pump and probe delay time. We found … Webb1 apr. 2024 · Recent advances in technology have allowed the production and the coherent detection of sub-ps pulses of terahertz (THz) radiation. Therefore, the potentialities of …
