Australian scientists and engineers require immediate access to frontier T-ray (terahertz radiation) technology to solve pressing current problems in semiconductor nanostructures and emerging problems in fields as diverse as biophysics and national security. Recent innovations now make practical the production of bursts of terahertz radiation by applying ultrafast optical pulses to photoconductive or electro-optic media, facilitating unparalleled time-resolved spectroscopy and imaging. The state-of-the-art equipment to be purchased and installed at Wollongong will enhance the existing excellent terahertz infrastructure (unique spectrometers, optically-pumped molecular laser) and efficiently service researchers in the dynamic Sydney (UTS, UNSW) - Wollongong (UoW) - Canberra (ANU) corridor.Read moreRead less
