T-ray imaging and spectroscopy both exploit the terahertz (THz) region of the spectrum. This gives rise to very promising industrial and biomedical appliions, where non-invasive and sensitive identifiion of a substance is achievable, through a material''s distinct absorption features in the THz band. Present T-ray systems are limited by low output power, and the race is now on to find
