Terahertz spectroscopy
Encyclopedia
Terahertz frequency radiation for spectroscopy is typically generated in one of three ways:
- time domain terahertz spectroscopy (TDTS), using ultrashort laser pulses
- photomixingPhotomixingPhotomixing is the generation of continuous wave terahertz radiation from two lasers. The beams are mixed together and focussed onto a photomixer device which generates the terahertz radiation....
, mixing two radiation sources to generate their difference frequency - Fourier transform spectroscopyFourier transform spectroscopyFourier transform spectroscopy is a measurement technique whereby spectra are collected based on measurements of the coherence of a radiative source, using time-domain or space-domain measurements of the electromagnetic radiation or other type of radiation....
